Featured Reviews for House Extension Professionals in San Ramon, CA

Impluvium Architecture
House Extension Professionals in San Ramon, CA
Average rating: 4 out of 5 stars20 August 2015
“Impluvium listened to my spiritual desires to create a contemporary space that made guests feel instantly welcome while providing function for everyday life. I described a desire that my home subliminally feel like a space where East meets West. Many visitors comment on how "happy", comfortable, and Zen like my home is. Mission accomplished thanks to Tim Haley! The project involved an extensive remodel of my 3 bedroom/2 bath townhouse inclusive of footprint expansions (addition of ~75 sq. ft.), relocation of all plumbing and electrical, removal of demising wall, new windows, doors and skylights, and creative solutions designed to maximize space. In particular, Impluvium not only designed an aesthetically beautiful ceiling in the great room, but it also provides layers of light for multiple uses at all times of the day and night, functionally it is a chase which delivers the in-home sound system and HVAC system, and it masks the new structural beam required when the demising wall was removed. The accuracy and completeness of Impluvium's design and architectural drawings were instrumental in expediting HOA approvals and permits.”

Average rating: 5 out of 5 stars17 June 2014
“Gwen Bertolami was respectful, knowledgeable and available. She was a total professional who attempted to work through all conditions to get our project completed in a timely and effective, accurate manner at all angles. At one point where she was slightly delayed and fully apologetic - we later discover she had a sick child in the hospital while trying to complete our work! Gwen was also very adaptive to working with the designer and contractor that we already had on the project. She was readily available for any changes later needed and her prices seemed extremely reasonable. I would recommend her and her abilities to anyone.”

“Tiffany is an exception architect. Her impeccable design sense, phenomenal attention to detail, and her ability to work magic with contractors and craftsmen is impressive. If you want a strong creative visionary with unmatched executional ability, Tiffany is the right architect. Very strong modern sensibility and has the capacity to lead projects across the architectural spectrum — she can do massive renovations and ground up work, to lighting and interior design, to landscape design. Highly recommended.”

“This team was contracted to do the architectural work on an addition to my home. I sketched out the overall design. Nong listened and offered his suggestions. At the conclusion, his overall design and improvements when far beyond what I had envisioned. He walk through all the paperwork and time needed to get all the permits which allowed me time to take care of the family and talk about the new look. The project is still under construction, but I know my family and I will be happy with what we both (myself and Nong) envisioned.”

Mikiten Architecture
House Extension Professionals in San Ramon, CA
Average rating: 5 out of 5 stars30 August 2014
“We hired Erick Mikiten as the project architect for a major kitchen remodel and some ancillary work on the entrance porches to the house in 1994/95. We wanted to expand the kitchen, remodel the interior to include new cabinets and an island, provide a new seating area in an addition at the rear of the house, and improve what was then an awkward connection between the kitchen and a rear bedroom. Erick came up with a very creative solution to the space constraints in the existing kitchen that resulted in a much more spacious kitchen with a larger island than we had anticipated. The addition on the rear of the house not only provided a seating area with views into the rear garden that we use on a daily basis, but included a very attractive raised ceiling and exterior architecture that continue to receive admiring comments from friends and visitors almost 20 years later. Erick's firm also recommended a new color scheme for the exterior of the house, which we adopted. Even now, from time to time complete strangers stop by to ask about the specifications of the paint colors because they find it so attractive and are considering doing something similar. Throughout the project Erick made great efforts to understand what we were looking for and present alternative options to achieve this, going through multiple iterations of the design as we refined the concept together, then producing a final design that satisfied our budget constraints. During construction, Erick visited the site on a regular basis and worked closely with the contractor to make sure that the work was being done in conformance with the design.”

“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.”

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 Ramon.

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.
