Featured Reviews for House Extension Professionals in San Marcos, CA

Allenbach Architecture
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars25 February 2017
“Mr. Allenbach has been very instrumental in my success as a builder in Southern California. I have had the pleasure of working with him over the past 10 years and is always surprising me on his vast knowledge of architecture and the building industry. He keeps his commitments and is always reasonable with his fees. I couldn't think of using anyone else for my drawings.”
Brewster's Drafting House
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars4 August 2022
“Brewster Drafting House is a GO-TO Choice for David Michael Designs, we have worked together for years now and he is one of the most responsive and clearly talented designers around. We have since worked on countless projects and I would highly recommend him time and time again. His work is fast, clean, sharp, and on budget. He is well versed in Lumion, and SketchUp as well as Chief Architect. I can not say enough good things here, it's a no-brainer choice. Our last client told me that he was so impressed with Brewsters 3D, that his wife was not sure how we had "Built" the house before we even completed the blueprints. She had thought the 3D designs were real..! - Davis Micahel”

Buffett Design
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars5 April 2015
“After meeting with a few different architects, we hired Buffett Design for our whole house remodel. Tyler is friendly, real, and was very understanding in regards to our constantly changing ideas. When it was difficult for us to visualize the space based on the 2D sketches, he created a 3D walkthrough experience on the computer for us. This was so helpful for us to "walk through" the new space before construction even started!”

BY Building Design
House Extension Professionals in San Marcos, CA
Average rating: 4 out of 5 stars24 May 2013
“We have used to Bob Yabarra on 3 projects that required as built drawings, and a two story house renovation. The products were professional, per our agreement, on time, and for a fare price. He is fare and though we made changes there was never an extra charge to us.”
Jeanne Liem Architecture + Design
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars25 August 2013
“I strongly recommend Jeanne Liem. My company worked with her on designing and building-out residential projects. Jeanne has a terrific aesthetic and is really hard working. She took the time to truly understand what we wanted and made our vision a reality. From beginning until the end, she has been very professional, responsive, proactive, and being able to come up with multiple solutions to simple and complex problems we encountered during construction. Their design elements are so elegant and well matched with our concept that exceeded my expectations in many ways. Also, they did all those within the budget requirements. They were flexible in all the areas we worked. She made everything so easy and smooth. I do not even want to imagine what would happen if we have taken another route instead of working with her.”
Kristin von Zweck, Architect
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars19 November 2014
“Kristin designed the remodel for my home in Encinitas. In a matter of a few hours she overcame design problems we had been struggling with for months, then went on to polish the design into a stand-out plan that has been a joy to live in. This was a complete home remodel. We expanded the master bath, added a new bath, moved and expanded the kitchen, expanded the living room, and added a studio. The end result took advantage of our 180-degree view (which the original design didn't) and cost far less than selling and moving into a comparable property with a similar view, if we had been able to find one.”

Average rating: 5 out of 5 stars21 December 2016
“Todd and Chuck were wonderful to work with from the onset of the project to its completion. It was a difficult time for us as we were recovering from the loss of our house during the firestorm of 2007. Todd's design was right on the money and the end result was a magnificent home. We would highly recommend Brazzon Danek for your architectural needs - Todd and Chuck won't let you down.”
Kim Grant Design Inc
House Extension Professionals in San Marcos, CA
Average rating: 5 out of 5 stars11 December 2015
“We worked with Kim to restore our 1920s Craftsman home in North Park. After interviewing several other architects, we knew with 100% certainty that Kim would be the perfect fit for our project. Not only did she come up with design and layout insights that we never would have thought of, she provided thoughtful, respectful and determined guidance throughout the project. She helped in every way possible... including the eventual Mills Act designation we received for the house. My husband and I are both very demanding, and high maintenance, clients, and Kim was able to keep us happy and content at all times. She's got an incredible relationships with contractors, builders and city officials. She's just the best... PERIOD. If I could give her 10 stars, I would!”

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 San Marcos.

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.
