Featured Reviews for House Extension Professionals in Bellevue, WA

Gelotte Hommas Drivdahl Architecture
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars9 November 2011
“My wife and I used Gelotte Hommas for our remodel. We have a 1937 Brick Tudor that when added onto we wanted it to look as if the new part of the house had always been there from an architectural standpoint. They did an incredible job using original designs and pulling them through on the exterior. They also gave us tons of ideas we would never have come up with on the interior had we done it ourselves. We are very a happy with the project. Our neighbors even comment on how well the new addition ties into the original house. That is the main judge of quality in my opinion!”
Lane Williams Architects
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars26 January 2013
“Lane Williams took our dated and very tired looking 1960’s one story, pitched roof home with a daylight basement and transformed it into a beautiful modern home with strong horizontal and vertical planes and cantilevered masses. Lane's vision for the house really came together when we decided to spend the money to expand the carport to two cars. We were thinking it might not work, but when he showed us the renderings we both just thought wow – it balanced everything out and got us a look that was spectacular. The finished house got great reactions from the neighbors, and it still thrills us when we overhear the bicyclists as they zip by saying ‘Cool House!’ http://coop15.com/images/house_shows/Enatai/Enatai2before.jpg http://coop15.com/images/house_shows/Enatai/Enatai3.jpg http://coop15.com/images/house_shows/Enatai/Enatai1.jpg”

“Nils Finne has a deep knowledge of design, a modern appreciation for craft and detail, and an uncanny ability to design homes with a fresh spirit and vitality. We've worked with Finne Architects on an extenstion renovation and a new build in a remote location, and in both projects we were impressed with Nils' ability to carefully listen to and translate our needs and values into the homes we love today. He's a consumate professional: on budget, on time, incredibly responsive, and always a pleasure to work with. ”
Coates Design Architecture + Interiors
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars25 May 2012
“We've toured the residential and commercial projects created on Bainbridge Island by Coates Design, and have followed their work for years. Our office was in the same building, and we often stopped in to learn more about their projects. We've always been impressed by their great architectural sense of aesthetics, and their ability to create innovative work that blends well into the surroundings of the project location. Very professional, very pleasant and very accomplished.”

“We LOVE working with Heidi at H2D A+D. Down to earth, super creative, and exceptionally organized. Having completed projects of all types and sizes we know first hand how important it is to have an effective leader guiding things from the beginning. Each time we work with Heidi the plans are thorough, clear, & easy to interpret… so that by the time we show up to perform our tasks, we are set up to do nothing but succeed. Each job has that enjoyable, team approach and energy. And who wins? Everybody! Thanks Heidi!”
SHKS Architects
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars24 August 2012
“I hired Theresa Freeman to design my kitchen, bath, laundry and entry and to relocate my basement stairs. Theresa drew preliminary drawings for me and after I chose the general layout continued to work with me on the details. Even when I changed my mind she patiently adjusted the drawings. She met with me and three contractors she had recommended. (I could not be happier with the contractor I chose.) She seemed to share my vision for my project. She was responsive and sympathetic. She was also my advocate. I depended on her expertise quite a bit from general design to little details. She is sweet but knowledgeable and appropriately resolute. How many people can say that their remodel was a happy experience?! I can.”
Prentiss Balance Wickline Architects
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars20 March 2013
“Professional, friendly, skilled, clever -- that's how I would describe the experience of working with Prentiss Architects. In any design project, problems come up, but it is how the problems are solved that is telling. We walked away happy. We are proud of and are still in love with our house in the San Juan Islands, 10 years later.”

“Tuvia was easy to work with, came in on budget and on time and had some great ideas. I would recommend him to any of my friends and we will hire him again for our next project.”
Scott Becker | Architect
House Extension Professionals in Bellevue, WA
Average rating: 5 out of 5 stars13 April 2014
“I have collaborated with Scott on several projects and can assuredly recommend him as a fantastic architect to work with. As a client you want your architect to listen and understand your goals, to put his/her ego aside and design what is practical and esthetically relevant to you and your family, and most importantly support you through the entire experience with utmost professionalism, knowledge of the process and understanding of your budget. Scott delivers all that and more; he is experienced in a variety of styles, has creativity and skills coupled with the analytical sense to construct a solution that is not only visually stunning but delivers good cost/benefit balance over the future years maintaining the space. If you happen to review his work be it modern, traditional, or Nantucket beach-home style you will find a correlation among all of them - spaces he designs are elegant and classy without loud statements that transients through time and connects each home with their owners.”
Rhodes Architecture + Light
House Extension Professionals in Bellevue, WA
Average rating: 4 out of 5 stars10 October 2013
“My wife and I have a difficult lot to build a house on due to its irregular slope, steep in some areas. In order to have a view of Puget Sound the main floor had to be as high as possible. Before hiring Rhodes Architecture + Light we met with a few builders who do their own design work. They were unable to come up with an acceptable way to achieve the floor height we need. This drove us to look for an architect. We selected Tim Rhodes because we liked his portfolio of completed projects and after meeting him felt we could trust him to do the job. Tim came up with a very clever design that incorporated all our requirements. We've been living in the house 14 months and are quite pleased. Tim's design gets many compliments from first time visitors. The only reason I didn't give Rhodes Architecture + Light five stars is cost estimation and control. Our construction cost ended up 40% above my desired target. To be fair this is common when building a house.”

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 Bellevue.

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.
