“We worked with Alexandra for a rebuild of our home, upgrading it from a 3bd/1.5 bath to a 4bd/3.5bath while adding a second floor and changing the layout of the house dramatically. We chose Alexandra based on two critical expectations: that she would be good to work with (after all, you spend countless hours with your architect on a very expensive project), and that she would share our philosophy regarding the importance of combining form and function in house design. We were very lucky to have chosen her. Alexandra indeed spent countless hours with us. She paid careful attention to our wishes and needs. She worked patiently through every detail of the house, helping us maximize not only our living space but also important functional aspects of the house. From beautifully located and proportioned stairs to storage for kids backpacks under an entryway bench and built-in cabinets to roof segments and their slopes, everything was thoughtful, detailed, and practical. Alexandra also showed great professional and personal skill in navigating the permitting process, developing a good relationship with the city’s planning department that allowed us to enjoy all the benefits of the zoning code. She was always ready to help and mediate successfully when issues inevitably came up with our contractor. She followed through with everything she said she would in an even, friendly, and professional manner. We are delighted with our home and, truth be told, also take joy in the many compliments we get from anybody who visits our home or even passes by it. Alexandra was wonderful and we can’t recommend her highly enough.”

“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!”

“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.”

He and the project architects in his office truly care about their work and know the latest codes and how to make space where there is no space. A designers and homeowners dream.

“The staff at Ohashi Design Studio helped me design my kitchen/living space. I wanted to open up our galley kitchen to be able to see our incredible view from the kitchen. They came up with a design I never imagined could work so well. Rather than just remove a wall, they moved the kitchen, changed it to a more functional shape and not only opened up the view, but made the living space feel like we were outside. I have been especially impressed with their level of service. They listened to my dreams and goals and turned it into a reality beyond what I'd hoped for. They were available anytime I needed guidance during construction and made sure the project was built down to the finest details. They helped me find a contractor and oversaw the bidding process. They helped pick out all the materials and finishes, even the paint color. I can't say enough about their level of expertise and professionalism. I worked with Dave and Alan.”

“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.”

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 Carlos.

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.
