AR Home Construction
House Extension Professionals in Nassau County, NY
Average rating: 5 out of 5 stars8 June 2022
“A R Home Construction was awesome. I was so nervous hiring someone I really didn’t know for such a big job. My first meeting with Tommy put me at ease I was sent a full estimate within 24 hours of meeting him. It was also a pleasure to deal with everybody in the A&R team they were all professional and courteous. The start date and the completion date for the project were right on target not many contractors can say that. I was also very impressed by Tommy‘s attention to detail and style he was instrumental in many of the decisions made on this project when it came to tiles and fixtures not only did he make suggestions but he actually accompanied me to retail stores to help make choices. I can honestly say that my house looks like something out of a showroom I feel A&R has exceeded my expectations in this project.”
DiCosimo General Contracting
House Extension Professionals in Nassau County, NY
Average rating: 5 out of 5 stars29 October 2016
“We have had two of our homes expanded and renovated by DiCosimo. They did outstanding work and very reasonable prices. In addition his people have been with him for a long time i.e. no short termers or newbies on his team. Also after the work is done, incidentally on-time and budget, he will always come back to deal with questions or problems of any kind - even years later. Bottom line is that we consider him to be "our contractor" and will always use him.”
Modern Citi Group: Renovations & Remodeling
House Extension Professionals in Nassau County, NY
Average rating: 5 out of 5 stars3 September 2019
“Hired this company for my kitchen renovation. Daniel was very easy to work with. What I liked the most is the communication that he and his team had with me. Literally every day I’d get a text from them, explaining what was completed today and what they will be doing tomorrow. I’ve had 4 renovations done before in my other apartments, but hands down, this was the smoothest one so far. Good luck to you guys!”

Sound Harbor Development, LLC

Average rating: 5 out of 5 stars5 March 2015
“I really can't say enough good things about Sound Harbor Development . They had built my house and the last thing to do was the basement which has just been finished . The millwork is so beautiful and the custom media room , laundry room , office, bathroom and rec room plus lots of great storage space which maximises every inch of space with great innovative idea's and this is just the basement which is just a continuation of the amazing design and millwork throughout the house . The contractor is a well renowned builder but such a personable person who's vision far exceeded my wildest expectations .I would highly recommend this to anyone ! if your lucky enough to get them .”
Development Design Services
House Extension Professionals in Nassau County, NY
Average rating: 5 out of 5 stars12 September 2019
“We are currently working with DDS on a significant exterior project that includes; roof, siding, masonry, and landscape design and we could not be happier with the services that are being provided! The attention to detail and professionalism is unparalleled. We have had several contractors provide us estimates and simply hand us a catalog to select materials with no guidance whatsoever. Edwin approached the project from an artistic point of view and was able to provide us with an image of what the house would look like upon completion which literally took all of the guess work out of the equation. Their team of contractors are very mild mannered and approachable and take the extra time each day to clean up and leave the work area spotless. We are beyond thrilled that we chose DDS for this project and look forward to our house being the envy of the block upon completion!”
Double D Contractors Inc.
House Extension Professionals in Nassau County, NY
Average rating: 5 out of 5 stars3 February 2014
“I'd give 10 stars if I could. They took on a fairly large job for me, with many moving pieces. It was such a pleasure working with this company. The workers were efficient, polite and cleaned up after themselves daily. I was given regular status updates. They even helped me sort through some of the insurance paperwork (headaches). I have recommended them, and will continue to recommend them to anyone who needs a reliable, honest contractor.”

Builder 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 Nassau County.

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.
