She is easy to work with and has great ideas but does not push anything I am not interested in (a problem I have had with past designer/architects). Patti has gone above and beyond what I expected by helping me find materials as well as subcontractors when by builder fell short. She is always a phone call or email away when I need her help and checks in with me to make sure things are proceeding. I don't have pictures yet but will add them when the project is completed. **★★★★★ — shellyb98, Feb. 2016** > We worked closely with Patti to create an addition to our house. She took the time to find out our individual tastes and hopes for the space, then included those details in the design in a way that fit our budget. It was a pleasure to work with her and we LOVE the addition! **★★★★★ — jojodenver, Oct. 2015** > Patricia is wonderful to work with! She helped develop the plans for our master bedroom addition and did a incredible job working with the us on the construction documents for the city of Lakewood. **★★★★★ — Van Matre Construction, LLC, Feb. 2015** > I have worked with a lot of architects, Patti is one of the ones that I consistently recommend. There are a lot of architects that can design good looking buildings and homes, but Patti is one of the few that can accomplish this and stay on track with the owner's budget. > I have worked with Patti on dozens of jobs with budgets from $50,000 to $2.5m, her attention to detail and aesthetic is consistent no matter the size of the job. Also, my clients like being around her; she is a nice person to be around and you will enjoy working with her. **★★★★★ — cabrewer1, Oct. 2014** > We worked with Patti Wilder Dallarosa, at Wilder Architecture & Planning, P.C., to design an accessory building to our home that incorporated a greenhouse, two car garage, and a studio. Because we live in a 100 year old home in a historic neighborhood, it was especially important to us that the new building look as if it had been built at the same time as our house, and that it match as many of the historic architectural details as possible. Patti was simply fabulous to work with on this project. She spent the time we needed to get to know us and to understand our expectations for both character and the functionality of the building. Once she had her first concept drawings, we met to fine tune, and then finalize, the design. Patti delivered on time, and on our budget \[Note that the project cost category selected below represents the estimate for both the architectural plans from Patti and the cost of building the project\]. What we also appreciated about working with Patti was that she is well connected with excellent builders and engineers – and we ended up working with people she recommended to build the project she designed. She also was available throughout the construction to consult with the builders when they had questions about the design. We ended up with a truly beautiful building that complements our house, and fits in perfectly in the neighborhood. Our neighbors also have told us how much they appreciate that it looks like the building has always been here. Plus the spaces – the green house and studio and, of course, the garage – function perfectly for the job they were designed to do. We have already recommended Patti to friends and colleagues, and we will definitely use her services in the future. **★★★★★ — dcfinneyrod, July 2014** > We used Wilder Architecture & Planning, P.C. to design our house in Santa Fe, New Mexico. The home is designed in the adobe home fashion complete with flat roof, vigas, niches, high ceilings and plaster walls, which is a bit different from house types in Colorado. Despite the long distance challenge Wilder did an excellent job working with Las Campanas HOA Design Board representatives and designing the house to meet the strict requirements of the area. Wilder was in constant contact with the contractor both before and during construction. This was extremely beneficial in completing construction on schedule and without issues from the Design Board. Wilder was also very helpful with both exterior design palette and interior design choices such as flooring, countertops, cabinets and fixtures. > > We highly recommend Wilder Architecture & Planning, P.C. for their quality, professionalism and willingness to go the extra step in making your house your home. **★★★★★ — henryjacobs, June 2014** > Patti Wilder Dallarosa patiently took our vision, produced tangible plans, and made the master suite addition to our home an innovative reality while considering our budget. She is detail oriented, precise, and timely. She became a part of the family as she worked hand in hand with us, journeying through all of the fine touches from start to finish. We would highly recommend Wilder Architecture & Planning, P.C. to anyone who desires a top notch, user-friendly architect. Patti excels in the three areas of most importance: Ability, Integrity, and Attention to Detail. ## Selected projects - [Erie Remodel & Addition](https://www.houzz.com/hznb/projects/erie-remodel-and-addition-pj-vj~2617486) - Location: Erie, CO - Photos: 40 - Description: This project was a remodel of the main portion of an existing home, with an addition of a new entry space and covered porches. - [Northern Colorado Greenhouse, Studio, & Garage](https://www.houzz.com/hznb/projects/northern-colorado-greenhouse-studio-and-garage-pj-vj~691745) - Location: Not specified - Photos: 12 - Description: This project in Northern Colorado, has a combination of functions, as well as, the concern of keeping within the context of the historic neighborhood.

These wonderful cabinets were actually matching antique dressers with mirrors that my client purchased and then converted into vanity cabinets with the vessel sinks, faucets, plumbing, and marble countertops. The drawers were modified to accommodate the plumbing. Sorry, I don't have a source to give you for ready-made cabinets like these. If you find one, please let me know. Thanks! Patti Patricia Wilder Dallarosa, AIA Wilder Architecture & Planning, P.C. patti@wilder-architecture.com www.wilder-architecture.com **Q: Where did you get the Farm sink?** *(in Photo Questions)* Do you know the brand of the sink or where it came from? A: Where did you get the faucet and control? **Q: Wall colour** *(in Photo Questions)* I'd love to know the wall paint colour. TIA A: Hi Stephanie - The color is Benjamin Moore \#2162-60, "Mystic Beige". This is from the Benjamin Moore Color Preview collection. Please let me know if you have any other questions. Thank you for your interest, Patricia Wilder Dallarosa, AIA Wilder Architecture & Planning, P.C. **Q: What color is the paint on the walls?** *(in Photo Questions)* A: Hi Michelle - Thanks for your inquiry. The wall paint color is Behr Ultra (Home Depot), "Fresh Day", UL220-11 Please let me know if you have any other questions. Thanks, Patricia Wilder Dallarosa, AIA Wilder Architecture & Planning, P.C. **Q: Column placement on each side of tub** *(in Photo Questions)* This might be a dumb question, but do the columns support the load without using a header for the windows? Thanks A: Not a dumb question, at all. The columns are strictly for aesthetic value in this instance. There are trusses above the ceiling which sit on the walls, and there are headers above the windows. --- *Source: Houzz professional profile. Reflects the profile as of 2026-09-09.*
