Norwell Design Build
House Extension Professionals in Palo Alto, CA
Average rating: 5 out of 5 stars15 August 2016
“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!”

“Kendra is a pleasure to work with. She is professional and knowledgeable and gave us lots of options about how to approach our remodel. She never tried to upsell us but rather offered clear advice geared toward exactly what we said we wanted. She also had ideas for the space we haven't even thought of. We can't recommend her enough!”

Average rating: 5 out of 5 stars28 November 2017
“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!”

Tali Hardonag Architect
House Extension Professionals in Palo Alto, CA
Average rating: 5 out of 5 stars26 February 2012
“Tali, with her professional skills and her unusuall ability to LISTEN and take in all the details and requests that we had for our complete renovation of our 60 year old ranch style home, created for us (and for anyone that comes in) a welcoming, comfortable, interesting and rejuvenating home. Throughout the whole project, from the conception stage until the completion we felt that Tali is not only a hired professional but also a parter and a friend. Another aspect of Tali's professionalism and good nature was evident when she had to communicate her vision and her plans with all the other professionals that took part in this project. ”

Average rating: 5 out of 5 stars29 March 2016
“Veronique figured out a great way to split one big bedroom our kids currently share into two bedrooms. She showed us a few different layouts, and using the 3D feature helped us get a better idea of what it would really look like. I usually don't see much on plans, but in 3D, you can really tell what it will look like. I love her design!”

Average rating: 5 out of 5 stars9 August 2023
“Sarit was awesome. We did a renovation of the house, and from start to finish Sarit set the tone. She listened to thoughts, and created a vision based on this. She is highly responsive, creative, thoughtful and supportive. Renovation can be trying and Sarit facilitated the process. Between creating renderings of the vision, working with the county for the permits, arranging and interfacing with the contractor, and designing the house, Sarit directed the project and was great. The outcome is fantastic, and I cannot tell you how much I appreciated Sarit's work here. I recommend her highly.”

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 Palo Alto.

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.
