Featured Reviews for House Extension Professionals in Mountain View, CA

Rolm Design Studio
House Extension Professionals in Mountain View, CA
Average rating: 5 out of 5 stars22 May 2017
“Mehran is extremely knowledgeable from a design, cost, and feasibility perspective. I worked with Mehran on a complete teardown/rebuild of an existing single family home to a 90% new home. The main factors I needed addressed were cost concerns while keeping the best design and functionality for resale. Mehran gave insightful opinion and pointed out issues I had not and was not able to spot due to my relative unfamiliarity. His years of experience allows him insight on issues from both a building and cost perspective that would otherwise go unnoticed. Highly recommended.”

“I was introduced to Bess through a previous Designer I worked with who was retiring her business. She felt Bess would be a good fit for me and my job, and I knew from our first meeting she was right. Bess and her Studio 3 team came on the job when we completed the basic house conceptual plan. Her input and ideas only further enhanced the function of the floor plan. As well, her knowledge, expertise and practical approach has been so valuable especially as this is my first major house remodel. I have quickly found how easy it is to keep expanding the plan as well as the budget! She does a great job keeping me on track and realistic, which my husband appreciates! Bess has guided us through our Phase 1 of the crazy permit process for an in law quarters and is now assisting with our phase 2, the rest of the house., all the while setting expectations of how to work with the city. She is also great when working with your personal choice of contractors, although she provides her own top notch referrals. Her team is friendly and responsive. We still have a ways to go, but she is willing to work with you on what services you need in regards to your budget, which I appreciate. I've been in Real Estate for 13 years, and one thing I've learned is when you find great vendors, partner with them, keep using them and refer them! I've referred Studio 3 to two people / clients with different styles and both have been thrilled to work with her. I would highly recommend you give Studio 3 and Bess a call for your next large or smaller project!”

“Anat helped me renovate and expand my 60 years-old start-up house. Anat modernized the layout and successfully extended the flow of natural light. Anat followed the project from inception to fruition, working out permits and coordinating contractors while at the same time helping me keep sane and within budget. It's great to have a good professional at your service, and Anat proved to be a great architect and partner for my project.”

“Dan was a great help to us in remodeling our kitchen. He was extremely professional and came up with some ideas we hadn't even thought of. He was thorough, timely and quick to answer any questions. We would work with Dan and his staff again.”

“2017-07-02 My husband and I had been thinking about remodeling our master bathroom for a few years, but we took our time to start it because we couldn’t find any designers we liked. However, after we had a consultation with Yuki, we had a good feeling that she would create our dream bathroom. She listened to our desires carefully and she created the design exactly how I wanted it to be. She communicated quite positively with our contractor and directed all the details of her design. Her advice was very professional and precise. Because of Yuki’s aesthetic design style, our dream bathroom turned out to be far better than we expected. We couldn’t go through the remodeling process without her. My husband and I are also planning an addition for our house in the future, and Yuki is the only person we will trust to work on our project again!”

“We had a great experience working with Mike and Ian at Norwell Design Build. They have a unique talent for setting an overall vision and following through with exquisite detail. As first-time renovators, we asked tons of questions and they listened, developed creative solutions and incorporated our ideas as well. In partnership, we were able to marry form and function in all the best ways. We *love* our home and would highly recommend working with them (and their incredible team) to create your own dream home!”

“Eugene Sakai stood out far above the pack of the 5 Architectural firms that we investigated to do our total house construction. He was simply the best to deal with, very professional, on time, and took a personal interest in the project, and within budget. We moved in 2 years ago and still love him and the contractor, C.W. Wright in San Carlos. We are pleased to show the house through Eugene Sakai at any time.”

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 Mountain View.

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.
