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.”

“I used this company for a bathroom remodel 2 years ago and now, for a living rm/dining rm hardwood floor installation and remodel. The work is outstanding, the workers show up on time and are trustworthy. During the bathroom remodel, the contractor was able to help design the area to maximize both the space as well as the finished look. My floor refinishing project is on time and looks great.”

“Carlos Arboleda is a contractor who is professional, patient and thoughtful. He wide knowledge of materials sources helped me create the look I was seeking. he often went above and beyond to solve problems and questions that came up and to reach the desired goal. I had hired Carlos and his team at a point months into my then floundering apartment renovation, not an easy way for them to begin. He listened carefully, offered suggestions and completed the work just as I would have imagined. Carlos and his team are a pleasure to work with and I am happy to recommend them.”

“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!”

“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.”

“I have worked with many contractors in my design career, and HOMEREDI is top notch. Gerard Zohouri and his team of workers are extremely knowledgeable, pleasant to work with, and efficient. They are able to finish projects on time and to completion, which is rare in this industry. I look forward to working with them again in the future.”

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 West Islip.

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.
