Featured Reviews for House Extension Professionals in Valhalla, NY

Stephen Barlow Architect pllc
House Extension Professionals in Valhalla, NY
Average rating: 5 out of 5 stars5 June 2020
“Creating a dream home is both dreamy and stressful. My family and I have had the honor and privilege of getting to work with one of the most talented architects on the planet - not once but twice. Stephen made both dreamy! Our first creation? A from the ground up Africa-inspired retreat in Kennebunkport, Maine on our family compound called Asante Sana ( Sensitive Information Hidden ). Just this morning, I was singing Steve’s praises for his architectural prowess. Our second project: a complete renovation of our home in Sea Cliff, San Francisco ( Sensitive Information Hidden ). Originally architect, Joseph Esherick would be proud. We even named one of our walls at Casa al Mare, the Barlow Wall - in Steve’s honor. I wish everyone would have the privilege of hiring Steve Barlow! When you hire the right architect you get 1 + 1 = 12.”
Michael Lewis Architects PC
House Extension Professionals in Valhalla, NY
Average rating: 5 out of 5 stars1 November 2014
“Michael Lewis is a consummate designer with years of experience, talent, and organizational ability. We felt supported by Michael and his able firm throughout our project. There was a culture of sensitivity to our needs throughout the firm and skillful handling of issues as they inevitably cropped up. The firm worked with our century old house to bring it into the modern age, by retrofitting an amazing kitchen into limited space and converting an unusable attic space into a dream master bedroom suite with dormers, increasing our living space significantly. We highly recommend this firm!”

Average rating: 5 out of 5 stars27 February 2016
“My husband and I were interested in a house, but saw some things that needed to be changed that were a deal breaker for us. I reached out to Stephanie and she fit it in her busy schedule to meet with us. Stephanie came to the house we were interested in and took a great amount of time walking through taking measurements and discussing all our options. She was very helpful , knowledgeable and full of insight.”

Average rating: 5 out of 5 stars16 September 2013
“Hudson Design designed and provided construction management for our 3,500 sq. ft. house in Cold Spring, NY. The design process was an iterative one with many revisions resulting in a modern, loft-like weekend getaway that we use almost every week. We have become friends with the principal of Hudson Design.”
Essential Design & Build
House Extension Professionals in Valhalla, NY
Average rating: 5 out of 5 stars25 June 2021
“I thought that finding an honest contractor who follows through with what they promise would be impossible but decided to take the chance with Essential and finally do my first renovation. I was very nervous at first but the contractor Peter was extremely patient and was with me every step of the way. His team which included a talented designer put together a picture perfect kitchen, powder bathroom and master bedroom bathroom. I was blown away by the attention to detail and if you’re looking for a wonderful experience limiting your stress level for such a major project then Peter and his team are a great fit.”

“I had a great experience working with Emilia. Her ideas were always very practical and smart but with a bit of the unexpected thrown in. The originality and expertise she showed in relation to design was a wonderful asset to have, and she incorporated them all so seamlessly into the overall project. And her attention to detail ensured all areas of the project were covered and taken into account so nothing was left out. I look forward to our next project together.”

ROAM Architecture
House Extension Professionals in Valhalla, NY
Average rating: 5 out of 5 stars16 November 2013
“I hired ROAM Design to design an addition of a family room to my home. In doing so, I wanted to maximize the current space I had, add the room and update my kitchen to make the space family friendly, open and comfortable. In planning the addition, Amy met frequently with my husband and I to get an understanding of what we wanted. She offered suggestions and options, always mindful of our budget and preferences. Her drawings were detailed and thorough, which enabled us to visualize the addition and helped our contractor price the work for us. Amy was always available and responsive to our questions and needs. Her fee was fair and she was upfront and honest regarding all costs. My husband and I were extremely pleased with all aspects of the work ROAM Design did for us and would highly recommend them. Amy went beyond her responsibility as our architecture in communicating with our contractor and providing suggestions to us. She is very detail-oriented and the details she incorporated into our addition are what makes it so special.In addition to adding value to our home, we love our addition and the opportunities it has afforded my family as a place to comfortably relax, spend time together and entertain.”
LPG Architect
House Extension Professionals in Valhalla, NY
Average rating: 5 out of 5 stars8 October 2015
“Lisa Gilbert, LPG Architect, performed two jobs for us. In 2008, she designed a porch and mudroom. In 2013, she designed a two-story addition that included a new master bedroom suite and kitchen, and a reconfiguration of existing space. In connection with the latter project, Lisa also represented us before the zoning board for a small variance. We found Lisa very professional and accommodating of our schedules. She initially presented us with multiple ideas and was detail oriented in the design process. The result is fantastic. She considered important drainage/water issues that were important for the design and we could not be more pleased with the space. We highly recommend Lisa.”

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 Valhalla.

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.
