I highly recommend MSK Design Build for home design, construction, and remodeling.

Congratulations to MSK Design Build on their multiple award-winning designs! We recently completed a whole-house remodel with MSK Design Build, and I’m happy to say our experience was absolutely fantastic. Their work was of the highest standard.
From our very first meeting with Kat and Scott, we knew MSK Design Build was the right fit for our project. They were professional, transparent, and easy to work with, giving us complete confidence that they would deliver a result we would love—and they did! When we met Kelly, our lead designer, we felt an instant connection. She immediately understood our vision and brought it to life with creativity and expertise. Kelly was communicative, easy to work with, and always brimming with fresh, innovative ideas. Not only did she make the design process exciting, but she also took a practical approach, ensuring that every decision aligned with our lifestyle. Her knowledge of the latest design trends was invaluable.
We were also fortunate to have Luz Mendoza join the design team, and at that moment, we knew we had hit the jackpot! Kelly and Luz worked seamlessly together, making the entire design phase smooth and enjoyable. With numerous meetings, discussions, and decisions to make, they guided us effortlessly through the process. Selecting materials—tiles, flooring, lighting, paint colors, and more—could have been overwhelming, but Kelly and Luz made it easy. We trusted their taste and expertise, and they worked tirelessly behind the scenes to ensure every order was accurate. Their dedication and research brought some truly outstanding features to our home.
Once the design phase was complete, the construction team, led by Curt (our project manager) and Joe Durron (our site lead), took over. They were incredible—professional, communicative, and detail-oriented. Curt kept us informed every step of the way, addressing any issues promptly. Joe, as our site lead, was an absolute rock throughout the construction process. He was always on top of every detail, ensuring that everything was executed flawlessly. His knowledge, problem-solving skills, and hands-on approach made a huge difference. No matter what challenges arose, Joe was always calm, efficient, and dedicated to making sure the work was done to the highest standard. He treated our home with the utmost care and always made sure the site was clean, organized, and secure at the end of each workday. His expertise and commitment gave us total peace of mind.
The entire MSK construction team maintained a clean and secure worksite, and we felt completely at ease with everyone coming in and out of our home. The subcontractors MSK Design Build works with are top-notch, which is crucial when undertaking a remodel that involves structural changes, electrical work, plumbing, and more. Throughout the construction phase, we remained in constant communication with Kat, Scott, Kelly, and Luz. They stayed involved, ensuring everything progressed smoothly and providing input when needed. Scott, with his engineering background, was especially helpful in refining the exterior details of the house.
I cannot say enough good things about this award-winning company. They turned our vision into reality, creating a home that is not only modern and luxurious but also functional and cozy. I highly recommend MSK Design Build for home design, construction, and remodeling. They are truly a gem in this industry. They are a 10/10 and we have referred them to many of our friends. Thank you, MSK Design Build!

MSK is exceptional.
MSK is exceptional.
We’d heard all of the remodel scares about projects taking 2x the time and the cost you plan on. No one we knew was willing to recommend their firms. But we are. It was on time and on budget, and that’s just the start.
From our reassuring early talks, to the fun we had doing design, to being wowed by the level of craftsmanship and detail, this team was everything we hoped for and now our house is too.
Special shoutouts to Kelly, Luz, Joe, Chris, Gary, Sean, Shawn, Pedro, and Carlos for being the best team around. What an incredible company Kat and Scott have built.
