House Extension Professionals in Healdsburg, CA
Average rating: 5 out of 5 stars25 August 2012
“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.”

“The thought of remodeling our kitchen was very overwhelming. I had some basic ideas of things I wanted changed, but had no idea of where to begin. Jessica listened to my wish list and used her professional, creative style and came up with a classic plan that we are enjoying more that we could imagine. Jessica was such a delightful person to work with !!!”

“My husband and I have worked with Harris & Kasten since the late 1990s. They have done many projects for us, including our lovely home in Atherton. Our home is a combination of Italian and French design. Everything was done to a tee! We could not be more pleased with their knowledge of art, art history, history, architecture, etc. You cannot go wrong with them.”

The Design & Building Works
House Extension Professionals in Healdsburg, CA
Average rating: 5 out of 5 stars28 July 2020
“The Design and Building Works was key in obtaining my building permit from the City of Santa Rosa. I was in need of having drawings, plans, and specifications done for the conversion of my garage into a 1 bedroom unit, an Accessory Dwelling Unit (ADU). The Design & Building Works put together drawings and specifications that required only one review by the Santa Rosa Building Department in order to issue me the required building permits. The drawings were complete in regards to referencing all of the required building codes, specifications and on calling out all of the correct details. Ellen Picard, owner is really easy to work with, detailed oriented, and has a very good reputation with the City of Santa Rosa Building Department. I highly recommend her and I would hire again for any project without a second thought.”

Orion Watkins Architecture

Average rating: 5 out of 5 stars4 December 2022
“Orion Watkins is incredibly talented, professional, and has been a pleasure to work with. We engaged him to design our pool house after he was highly recommended by a friend of ours in the building industry. We had a clear idea of what we wanted. Orion listened to our ideas, then made great recommendations, including relocating the building to another location on our property resulting in a much better design and more functional building. He is responsive and consistently followed through on his commitments. We would happily work with him again on a future 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 Healdsburg.

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.
