Featured Reviews for House Extension Professionals in Herndon, VA

Horizon Building Corporation
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars19 June 2023
“Between 2002 and 2003, Michael Ipsan/Horizon took a small 1,800 square foot circa 1942 farmhouse and integrated an addition that more than tripled the size of the house and resulted in a beautiful contemporary farmhouse, with upgrades to plumbing, electrical, windows and siding in the original part of the house. The integration was seamless and the project came in on-time and on-budget, with wonderful workmanship. While we had retained an architect for the overall design, Michael made many useful suggestions on tweaks to the design that significantly improved the outcome. The kitchen and pantry were recognized by HGTV in their American Home 2005 show, and in 2008 the house was recognized with a spot on the Historic Garden Week in Virginia tour, both testaments to the quality of the construction. We've had other friends who've had nightmare construction projects with other builders; our experience was exactly the opposite. Warranty issues were minor, and Horizon has stood behind the construction even to this day. In the years since it was completed we've been happy to have Michael walk other prospective clients through the house to see what was done, which speaks to our respect for his work and honesty. We can highly recommend Horizon to anyone considering a custom home builder.”
SB Builders & Construction Inc.
House Extension Professionals in Herndon, VA
Average rating: 4 out of 5 stars7 May 2018
“Construction & remodeling is a big business. There are many small & large companies competing in the field. What stand out about SB was 1- their estimates were very close to the actual cost, 2- they did the job on time & 3- they made no excuses like lots of others I have seen because they didn’t need to. Professional staff with great service. I do recommend them for anybody looking to do work on their homes.”
Bowers Design Build
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars20 May 2013
“I have worked for several years with the owners and designers at Bowers Design Build. In the course of my work as an architectural photographer, I have met hundreds of homeowners who have worked with dozens of builders. As I work in their homes (photographing them for Bruce and Wilma) I constantly hear how easy they are to work with, how responsive they are to their clients' needs, and how completely satisfied they are with the whole experience of having the Bowers' firm do their project. I am always happy to photograph another award-winning Bowers project because quality work makes for quality photography, and that works for me.”
Hammer Design Build Remodel
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars19 July 2013
“Greg from Hammer Contractors was one of the best I've worked with. We have not actually started the work yet, but he gave great information and outlined the steps involved in getting it done. He was punctual, and always followed up with an email to check the status of my talks with the bank. He was always respectful and actually listened to us. We will definitely be working with him again.”
Thomas Custom Builders
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars28 June 2012
“After receiving several estimates to turn our attic into a master bedroom suite with a bathroom, we went with Thomas Custom Builders (TCB). They did not provide the cheapest estimate we received, but they were extremely professional, provided the most thorough information, seemed focused on doing things right, and we were really comfortable working with them and communicating with them. We are extremely happy we went with TCB. The renovation process hasn't been perfect - which is really not possible - but TCB has been excellent at finding solutions to the unforeseen things we could not anticipate. More importantly, they do things the right way and are honest about what is going on and what needs to be done. This was our first renovation, so we asked a ton of questions, but the entire TCB team always took the time to talk us through stuff and answer any questions we had. Lastly, the quality of their work is superb. We've had some neighbors over throughout the process who have gone through several renovations and they commented that they could tell TCB were true craftsmen based on the quality of their work. I would highly recommend their services and will hire them for any renovation work we do in the future.”
Erika Jayne Design Build
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars25 February 2019
“Erika is truly talented. We hired her to update and remodel the kitchen, living room, bathrooms and foyer in our recently purchased home. We immediately knew that we were in good hands. She took the time to ask the right questions and really listen to my husband and I as we described what what most important to us. Her designs maximized space, minimized unnecessary expense and transformed our house (built in the 1980's) into a fresh and modern home. When it came time to decorate, she selected furniture and accents that fit our design aesthetic and more importantly our lifestyle. I certainly have a taste for the finer things, but with a dog and a baby, we wanted to make sure that we were smart and economical with our purchases. Erika took all of this into consideration while sourcing items for our home, finding us items that we not only loved, but could feel good about buying for our family. My husband and I joke that Erika knows what we really want before we do, but it's not really a joke. She puts great care into her work and it's incredibly important to her that her clients love the finished product - and we most certainly do!”
WINN Design+Build
House Extension Professionals in Herndon, VA
Average rating: 5 out of 5 stars27 August 2012
“We have used Winn Design on two different occasions. The first, in 2007, was a project to replace the exterior doors, windows, and siding of our 1969 ranch house. As part of the project, we added a natural wood portico to the front entrance. More than 5 years later we still have people stop to take pictures and ask us who has done the construction. In 2010 we contracted again with Winn to extend and completely remodel our kitchen. As this was our first experience with a project of this size, the design process was very daunting. However, Winn patiently worked with us over a few months through many revisions until we had a design that fit our needs and budget. During construction we went on vacation and the project manager sent us pictures and summaries on almost a daily basis so that we could keep up with the progress of the project. As the different trades came to the project we were impressed by the quality of the subcontractors Winn used. Several trades mentioned that Winn was one of their favorite companies to work with. Happy and skilled subcontractors are also key to a successful project! Renovations can be very intimidating and stressful on a marriage. We are very grateful that Winn, through their professionalism and quality of work, made the process as pleasant and successful as we might have hoped for. Now, with more than 2 years behind us, we know that we made the right choice to use them. There are many contractor horror stories out there, but you won’t have one with Winn.”

“I had the pleasure of hiring Finecraft for a project recently that called for the addition of an outdoor living area to my home. The level of detail and commitment to quality was unsurpassed. These are Craftsmen, not contractors. It shows in every project they create. JF Homeowner”

Average rating: 5 out of 5 stars27 December 2023
“Very professional team starting from the sales representative to the installers. We went from an almost non-usable space because of the heat from the sun to a large outdoor space. This pergola is built to last with hardly any maintenance. Would definitely recommend Dream Design Construction.”

“Nick is a true professional! His attention to detail and eye for style is unmatched. His renovation of our home was done exactly the way he said. He supervised the construction as well as assisted in the design process. His comments and thoughts were always towards maximizing space and style while keeping costs as expected. A true professional and a very kind man as well.”

Design and Build Company 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 Herndon.

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.
