Featured Reviews for House Extension Professionals in Santa Rosa, CA

Dotter & Solfjeld Architecture + Design
House Extension Professionals in Santa Rosa, CA
Average rating: 5 out of 5 stars1 November 2012
“We worked with Dotter & Solfjeld most recently to design an Italian villa on a hillside in Saratoga, CA. This was actually our third project together as they worked on an expansion and remodel of our previous house in Palo Alto as well. As soon as we bought the lot in Saratoga Russ and Wencke, of D&S, began studying the landscape, spending significant time at different points in the day to intimately understand the light, the views and the flow of the hillside. Russ and Wencke are experts at both exterior and interior architecture and design, and they are an amazing team! Once they felt they knew the property, they spent time with us to understand what we liked and disliked and then began designing our house based largely on Italian building principles of thick walls and simple, yet elegant, construction. D&S involved us in every step of the process and ensured we were completely comfortable with each phase of the design before moving forward. They totally went above and beyond the call of duty by diligently working with our planning department and even one neighbor. They were our advocates with the City and were clearly extremely well respected by everybody they interfaced with. During the building process, D&S worked closely with our contractor and foreman to ensure that the project ran smoothly and stayed on budget. Often times, there is tension between architects and contractors, but our contractor loved working with D&S. Some of our friends have also used D&S to design ultra modern homes...D&S is super versatile and we unequivocally and enthusiastically recommend them.”
Lincoln Lighthill Architect
House Extension Professionals in Santa Rosa, CA
Average rating: 5 out of 5 stars28 April 2023
“We were in a unique situation - an opportunity to do some remodeling after a house fire. With the insurance budget parameters, we were still hopeful we could make some beautiful improvements to our home. Lincoln was the perfect person to partner with. He helped us envision simple, creative and impactful changes to our home that included opening our dining room up so that the best view in the house (from a kitchen window) was visible from the living and dining rooms. He listened to our wish to host larger dinner parties and created a movable ceiling light, so it can always be centrally positioned regardless of how long our dining room table might be. He worked with our more conservative contractor and helped advocate for our ideas, finding modern, sleek textiles and cabinetry that immediately increased the value of our home. A back hallway became a pantry; a small closet in the bedroom was expanded to become a little walk-in closet. We built in a post-modern ladder to the attic, an interior wall window to bring more light into the bedroom and many other details we wouldn't have thought about. Lincoln's vision and experience elevated our home and it turned a disaster (fire) into a huge opportunity! I highly recommend collaborating with Lincoln on your next project, big or small.”

“The thought of remodeling our kitchen was very overwhelming. I had some basic ideas of things I wanted changed, but had no idea of where to begin. Jessica listened to my wish list and used her professional, creative style and came up with a classic plan that we are enjoying more that we could imagine. Jessica was such a delightful person to work with !!!”

Architect or Architectural Designer FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Santa Rosa.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
