Add a Second Floor to Your Des Moines Home with a Trusted Local Home Contractor

Convert your house from single to double story with a functional second-floor addition. Our design and build team at Zenith Design + Build will increase the space and value of your home.

We’re An Award Winning Remodeling Company

Types of Second Floor
Additions

Second story additions vary in scope and size, depending on your home size, budget, and the amount of additional space you require

Partial-Story Addition

Partial second-story additions are ideal for those who need a smaller amount of space in the form of one or two extra rooms and a bathroom.
Full Second Story Addition

A full second-story addition matches the size of the first floor and doubles the house’s size, offering space for multiple rooms, bathrooms, and living areas.
Second Story Addition to Your Garage

A second-story addition to your garage adds valuable space that may be used as an office, bedroom, or additional dwelling unit for family or rental income.

Benefits of a Second Story Addition

Second story additions are a great way to add value to your life and home. They have many benefits:

01
Double your living area’s square footage with more bedrooms, bathrooms, offices, recreational areas and balconies
02
Because you’re expanding vertically, you won’t have to sacrifice valuable yard space
03
Immediately increase your home’s resale value
04
Gain the extra living space you need without having to sell your home and relocate elsewhere
05
Enhance your home’s curb appeal with a facade facelift
06
Add customized living areas your home currently lacks, like a rec room, extra bathroom, hobby room, or bedroom/s
07
Avoid a depreciating house market and costly fees when selling and transferring homeownership

We decided to remodel the first floor of our townhouse last spring and decided to go with Zenith. They put together a plan for us and then got to work. Jarrett and his team did an excellent job executing the plan. Ty built us beautiful cabinets. Their communication was great and they were there when they said they would be. Any of our concerns were always immediately addressed and taken care of. We are very grateful for all the hard work each of the people did for us. We would definitely recommend!

We recently completed a basement renovation with Zenith Design + Build, and we could not be happier with the entire experience. From start to finish, the project was handled with incredible organization, communication, and professionalism — qualities that truly set Zenith apart. A huge shoutout to Jarrett, our onsite project manager, who was exceptional in every way — responsive, proactive, and always a step ahead in keeping things on track. Mark and Simone were also wonderful to work with, bringing thoughtful design input and keeping every detail organized. The team’s timeliness was remarkable; we’ve never had a renovation project stay so perfectly on schedule! We also want to recognize Matt for framing, as well as Chris, Bryant, and David from Zenith Electric for their excellent electrical work. Their quality of craftsmanship and professionalism matched the high standards set by Zenith’s entire team. Even the subcontractors Zenith selected — like Aspen Aire for HVAC — were outstanding. It’s clear that Zenith partners with top-notch professionals who share their values of excellence and communication. Overall, this was hands-down the best experience we’ve ever had with a home renovation contractor. We highly recommend Zenith Design + Build to anyone seeking a smooth, well-managed, and beautifully executed project!

The answer is yes, if we had to do it all over again -- we would use Zenith Design + Build again. Our project has been wrapped up for a little over 45 days -- I delayed my review because I wanted to rationally internalize the entire scope of our project along with my level of satisfaction. I was expecting a high level of quality and craftsmanship, and the team did not let me down. Mark and Simmone kicked off the design and scope of the remodel and built the foundation for our transformation. Simmone happily worked through all of our design tweaks and steered us to a plan that met our requirements. Jarrett was superb as our on-site superintendent was responsive in working though challenges as they surfaced. The attention to detail and craftsmanship of Tyler and Vic brought everything together with the finish carpentry and exceeded my expectations. If you are considering a remodel project and looking for exceptional team to partner for your project, you owe it to yourself to give the Zenith team serious consideration -- you wont be disappointed.

Kelly, we can’t thank you enough for your kind words. Your feedback means so much to us—not only as encouragement for our team, but also in helping future homeowners feel confident in choosing us.

My wife and I met with Ben to discuss potentially working with Zenith on our kitchen remodel. While we ultimately decided to go a different direction, we were incredibly impressed with Zenith. Ben was absolutely great to meet with, providing us with tons of useful information and really listening closely to our ideas. You could tell he is passionate about his work and wants to help people create the best spaces they can. If it works out in the future we would love to be able to work with Zenith on different home projects.

This spring we had Zenith add a 14x18 four season sunroom along with a maintenance-free deck and we could not be happier with the final product. Olivia did a wonderful job working with us to design all the elements we wanted. It was amazing to see the 3D images she produced so we knew exactly what the final build would look. Mark who was the project manager was the one involved in ordering all the necessary product, scheduling deliveries, and making sure everything ran smoothly from start to finish. The speed at which this project was done with shocking. Only about 6 and 1/2 weeks.Jarrett, who was the on-site supervisor was amazing. He was on the job site every day and was continually looking at the quality of work to make sure it met our expectations and Zeniths. His continuous communication always kept us in the loop regarding the construction timetable and the products that would be drop shipped at the home. He was also involved in continually looking for areas that didnt look quite right so corrective action could be taken. Buddy was in charge of quality control to make sure everything was done to Zenith standards. He made frequent visits and was always looking to make sure everything was as we wanted. We were really surprised how much attention Zenith paid to quality control. Ive never seen a company so dedicated to this. Brian and Briar did a majority of the framing and window installation. I was shocked how meticulous they were. Everything lined up perfectly to our existing home and screws, rather than nails were used in many areas to lock everything together. Zenith has done an excellent job vetting their contractors. All had great people skills and were masters of their trade. You could tell they knew what they were doing and did so with complete confidence. The final result of our project proved that! There was not one aspect of our project that we had reservations about or questioned the quality of their work. I would absolutely recommend this contractor without any hesitation. Thanks again Zenith for a wonderful experience. Our home is beautiful thanks to everything you did Mike and Olya (Bri and Mia too

Wow Mike! Thank you for your kind words! We are so grateful to have the opportunity to work with you and your family. Its amazing clients like yourself that make what we do so worthwhile.

We interviewed several design companies to lift the back dormer of our home to add an office and en suite bathroom. We immediately knew Zenith was the company we trusted to bring our vision to life while respecting the bones of our 100 year old Craftsman. From the very beginning when Olivia showed us the initial plans and Matt presented us the budget, to Jarrett being almost daily onsite visits, we were in the best hands. We have done major projects ourselves and know how hard it is to balance contractors, costs and timelines, but there wasn’t a day we didn’t have someone here moving the timeline forward. Our project was finished on time and within the budget presented to us. Olivia was able to blend our styles and truly listened to us. She created and curated spaces that are traditional enough to honor our home’s style, but making it beautiful and modern - plus repurposed a space to give us a walk in closet. She was so patient when going through the choices and never forced us to settle, she instead found other options. Jarrett was the best supervisor. He was able to keep the contractors on time and verified the work was perfect. He treated us like we were family and treated our project like it was his own - relieving us of a great deal of stress. We would choose Zenith again in a heart beat and could not recommend them more.

Response from the owner

Thank you so much for your kind words. Hearing that you felt cared for and supported through every step of the process means everything to our team. When I (Nicholas) walked into the office this morning, Jarrett immediately asked if I’d seen your review—then Matt and Olivia followed. They’re all thrilled to know their hard work made such a difference. I’m so happy for your family and proud of our team for creating such a great experience. Thank you for trusting us with your home—we are so excited for your family to enjoy this for years to come :)

We’ve done two projects with Zenith. A partial basement finish/office in 2020 and now a kitchen remodel/addition in 2025. Our supervisor Jon was great to work with and always in constant contact during the project and issues were addressed timely. The team of Jon, Mark, Vic, Buddy and owner Nicholas were great to work with from start to finish! If we do another project will use Zenith again!

Hi Jenny! We cant thank you enough for coming back to us for a second project—it truly means so much to our whole team. It was an absolute pleasure working with you again, and we’re so glad to hear Jon, Mark, Vic, Buddy, and Nicholas made the experience a positive one from start to finish. We works hard to keep everything on track and everyone informed, and we’re proud to have the team that we do.

When my wife and I decided to remodel our first floor, encompassing our kitchen, dining room, and living room, we were inundated with choices. It was a daunting task, to say the least. Thats when we stumbled upon Zenith, and from the very first interaction, we knew we were in good hands. Zeniths professionalism was evident from the get-go. Our project manager, Amy, took the time to sit down with us, listen to our ideas, and understand our vision for the space. What truly set them apart was their commitment to transparency and communication. Every step of the process, from design conception to final delivery, was meticulously laid out and thoroughly explained. We never felt in the dark or pressured to compromise on our vision. They set a construction timeline, and not only did they finish on time, the project was completed two weeks ahead of schedule. The team at Zenith not only met our expectations but exceeded them in every way possible. Our project’s superintendent, Jay, attention to detail was impeccable, ensuring that every aspect of the remodel was executed flawlessly. And when we ran into two small issues during the final walkthrough- a ding in a cabinet drawer and a loud garbage disposal - they fixed the issues immediately at no extra cost. Moreover, the dedication of the Zenith team members Vic, Chuck, Briar, and Elmo, was truly commendable. Their hard work and commitment to the project were evident every step of the way, contributing to the overall success of the remodel. But beyond their technical expertise, it was the personal touch that made working with Zenith truly exceptional. They treated our home as if it were their own, respecting our space and keeping the disruption to a minimum. Their dedication to customer satisfaction was evident in every interaction, making the entire process stress-free and enjoyable. Thanks to Zenith, our first-floor remodel surpassed all our expectations. Its not just a space; its a reflection of our style and personality, brought to life with the help of a truly exceptional team. If youre looking for a general contractor who will turn your vision into reality without compromise, look no further than Zenith.

Everyone was so great. I was impressed from the start with Zenith. With Jess, when she first sat with us and helped us with the beginning features/reality. Julietta provided beautiful designs and listened to our tastes. Jon kept in touch and stopped by every so now and again checking in on the progress and answered any oddball question we had. We now have such a lovely porch where I can listen to the cicadas/other bugs and not get attacked by them! Thank you all so much.

We recently completed a four month long, whole house renovation with Zenith D+B and we are beyond happy with how things turned out! Our designer, Lauren Hasselbusch, was thoughtful and did such an amazing job helping us research and select the right finishes. Five stars go out to Mike Johnston, our superintendent, who always had a smile and a solution to keeping things moving forward. Our project craftspeople and all the trades that helped were professional and provided the attention to detail we were hoping for. The true Dream Team of the project were the carpenters who did such an amazing job: Brian VanDenTop, Briar Knapp and Tyler Fritz (thanks for our awesome pet door!!!:) All construction projects have their challenges, but Zenith did an incredible job of keeping ours on schedule andwithin budget. I highly recommend Zenith for any size project-if they cost a little more-trust me...theyre worth it. They care and it shows in everything they do.

Response from the owner

Thank you so much for the kind words Kelly! Our entire team really loved working with you, Tom and the animal kiddos.

We are glad they could take part in the journey through the project and make some great relationships as well :) We are passionate about transforming communities, families, and lives through the work that we do and we couldnt be happier for you and your family and we feel truly blessed to get to do what we do and who we do it with! Thank you again Kelly and Tom for being such great partners through our project together.

We used Zenith to design and renovate our kitchen, laundry/powder room, and staircase. Jess initially made us feel so comfortable and like Zenith would be the best fit for our project. We couldn’t have been happier with our designer Lauren who helped bring our vision to life with her expertise. Our project stayed on track and within our budget thanks to our project manager, Jon! Zenith has a great team, does great work, and was always extremely professional and kind. We would recommend them over and over for any of your project needs, and would use them again in the future!

Zenith was fantastic to work with and stayed ahead of their timeline. Jess, Amy and Vic were always available for any questions or concerns that we had. Amy paid attention to every detail and helped us create and bring to life a home we will enjoy for decades!

A big shout-out to Zenith for standing behind their work with their warranty program. When an issue developed with the new tile floor in our main bathroom several months after installation, and relatively simple fixes didnt solve the problem, they replaced the entire floor at no cost to us. It was a lot of work for them—taking everything out of the bath, tearing up the old floor, laying new tile, and putting everything back together—but they coordinated it so we were without our bath for only a few days. Special thanks to Vic, Chuck, and Avian from Zenith (I know Im missing a name or two), and Simon the tile guy for all their great work. Weve done two big projects with Zenith so far (interior and exterior) and are so glad we chose them.

Amy created a layout that exceeded our goals for our basement project and her materials expertise helped the new space blend into the original house seamlessly, including tracking down the flooring which had been long discontinued so we could use it in the bathroom. Vic and Jon were instrumental in ensuring people knew where they were supposed to be, when, and managing the overall project. Additionally, Jon was our liaison throughout the construction process, and we appreciated that we could trust him to proactively keep us abreast of timeline and progress updates and help us navigate any questions we had. We were extremely pleased with Zeniths design process, the teamwork and partnership we had with them, and are loving our newly finished basement!

We are very happy with the job Zenith did recently for our home remodel. Our interactions with every staff member were always pleasant from the very first meeting to our last, and we were especially impressed with their commitment to customer service and satisfaction. Nicholas and Jessica worked with us initially to find a design that fit within our budget, and we were thankful for Laurens helpful design suggestions and ideas. Once the project began, there were a couple of hiccups (specifically, in regards to the painting), but Matt Garcia went above and beyond to remedy this issue for us. Aside from that, the project went by smoothly and we want to thank our project manager Mike for that. We also enjoyed getting to know many of the other team members throughout the duration of the project, who always seemed genuinely happy to be there and cared about the job they did. Chuck, in particular, took great pride in his work and was always happy and willing to address any questions or requests we had. We love our new home and certainly wont hesitate to contact Zenith again for any projects we may have in the future.

Thanks so much for the kind words Jeff! We had so much fun working with you and MacKenzie. We hope you and the family enjoy the space for so many years to come! Also, I hope you are all settling into the US now :)

We engaged Zenith Design+Build to restore two fire-damaged townhomes in downtown Des Moines, with one of the townhomes having been gutted to the studs. We really appreciated the friendly and professional staff from Zenith that helped crystallize the plan for repairs, and then methodically worked to execute the plan. We worked primarily with Michael, Josh and Lauren during the early planning for the renovation. The detailed floor plans and 3-D renderings that they prepared for the project helped us efficiently discuss fine details of the reconstruction. I was pleasantly surprised at the outset of the project when Zenith made a design proposal, involving the thoughtful positioning of doors, that enabled us to have a full size closet in the guest bedroom we had envisioned for the ground level of our townhome. I had been concerned that we would potentially have to work with a designer who would present design choices that didnt match with our vision for the space, or would be unwilling to accomodate our requests. It was almost spooky how Lauren time and again would present us with options that inevitably included an item that was the right match for our design tastes. The only notable design modification I requested after work started was on the framing of the wall over the living room fireplace to better accomodate a large TV in a fairly limited space. Zenith was able to work with me to get this modification made in elegant fashion. I cant say enough about how great it was to have Jay as our project foreman. He clearly cared alot about the quality of work that was being done on the site, and whenever there was a setback (such as a water leak that necessitated additional drywall work, or a subcontractor failing to complete a task on time), I always had the sense that Jay cared at least as much as I did that the work be completed efficiently so we could get back home. He was always approachable, friendly, and calm on the job. I wouldnt hesitate to ask for Jay to be foreman on any future jobs I may engage Zenith to perform for us, and would wholeheartedly recommend him to friends.

Thank you so so much for your kind words Peter! We really appreciate your feedback. I speak for our whole team when I say you were so great to work with.

We worked with Zenith on a bathroom remodel in our 1950s mid-century home – looking to add some character and improvement upon an outdated (not original) full bathroom. The consideration of how we use our home – as well as our cats! – alongside provided inspiration photos was reflected almost immediately in the design process (did YOUR designer put your cat in your renderings?!). Lauren, our designer, truly helped turn our wants (and the didn’t-know-we-could-do-that’s) into reality! Jon was incredibly helpful with the day-to-day stressors and schedules, and attentive to things that needed to be handled or amended along the way. We sincerely appreciate the team for their attention to what we were trying to accomplish. While home remodels rarely feel fun” in the process, the result more than exemplifies the FUN we were looking to incorporate into our home. We could tell that our home and this project was important to them, too – and that really made this an overwhelmingly positive experience. Also, shout out to Keith for his awesome custom cabinetry (and cat hideaway).

We did a whole house remodel that was originally designed and built by my parents. The changes were in our heads. We shared with Jessica Bailey, and she started the process off, getting the Matterport photos of my Childhood home and walking us through the process. Our Designer, Julieta Linhart, went to work creating a beautiful design and assisting us in selecting all our finishes and materials. The construction process was managed by Jay Street, which his constant pursuit of detail was so comforting. Ian Brandt, production manager, told us at the beginning there will be highs and lows, and there were. But the lows were always managed, then corrected with great detail, passion, and care. The whole process has left us overwhelmed with joy. My childhood home has been turned into my wife and my dream home. It was all because of the care and passion of the entire Zenith Design + Build team!!!!

Zenith has been wonderful to work with. We started our whole house remodel and addition journey with Jessica our design consultant who has been awesome to help us along each step of the way. Julieta our designer has gone above and beyond in helping us with design. Lauren helped measure the entire house which was no easy task. Mark J. was strategic with helping us narrow down options and estimates for pricing. Working with Ian our project manager and Jon our SUPERintendent has been such a wonderful experience. We are mid project at this point but giving a shot out to Nicholas and his team for all their hard work in getting us a home we look forward to moving into. This house was my childhood home and we are grateful for Zenith helping us bring it into the next generation.

How Long Does it Take to Build a Second Story Addition?

Building a second-floor addition takes a few months, depending on the size of the addition, design features, and how much of the first-floor walls need fortifying.

03.
Why does a 2nd-floor addition cost more per square foot than the 1st floor?

A second-floor addition costs more because, typically, the existing roof has to be removed entirely and replaced. The first floor may also require the installation of additional structures to ensure the second-floor addition is securely supported and connected to the first floor.
