AK BUILDING FOR YOU LTD
House Extension Professionals in London, UK
Average rating: 5 out of 5 stars15 September 2023
“It was such a relief to find builders we could trust. Before and during the build we found them to be reliable, trustworthy, hard working, to listen and take our desires on board, but to also offer suggestions and ideas to make things work better. They were also considerate, friendly people. They left the site tidy each day. They even covered the skip to minimise unwelcome contributions! The job is now complete and we are very happy with the result and with our choice of builders. Things went pretty smoothly and it was always a pleasure to deal with them.”

“The most efficient and friendly staff, highly professional team that can execute your kitchen dreams and desires to an exact specification! The expertise that the team had from the inception with the detailed drawings with great design ideas and 3D visuals created by Sonya, and the level of detail from the installation manager Avtar who was on site during the process and the complete knowledge of every aspect of a kitchen from appliances, accessories, colour schemes and materials and the utilization of space from the directors Ajit and Sukh gave us clear confidence in their work and passion for the job and service provided. They were extremely personable, warm, friendly and charming and a complete joy to have been serviced by. The finished product has been complimented by every guest and is now clearly the highlight of our home. Would highly recommend to anyone looking for a great quality kitchen with fantastic service to go with it! Our family thank you Design Abode for realising our dream kitchen. One happy customer!”

“I have used Chris and his team at R.A.S Construction for several 'full service' projects (covering refurbishment, extending, plumbing, re-wiring etc) - each time the work and service has been exceptional. We received a detailed, competitive quote and the work was completed on-time to a very high standard. I would have no hesitation recommending them or using again. He provided references and gave the opportunity to view past projects (we were so impressed by the work and dedication that we were happy to have potential customers contact us and even view our finished projects).”

MoreSpace
House Extension Professionals in London, UK
Average rating: 5 out of 5 stars29 January 2021
“We decided to choose MoreSpace to build our loft extension and were so glad we did. We were firstly consulted by Stuart Ellerby who gave us a thorough overview of what was involved in a loft extension and who is responsible for what during the project. His knowledge was first class and he spoke in layman’s terms and not jargon which we found very engaging and brought it to life. Once we agreed on the project, Stuart also kept in touch throughout with regular site visits and was also super responsive when we raised any questions. His aftercare has also been great. The team who built our loft was insane. The team was led by Jake and everyone in his team were super friendly and accommodating, whether it was popping up for a sneak peek on progress, asking any questions or looking to make slight adjustments. The finish of the job is perfect and exactly what we’d hoped for. They left the place clean and was complete within a much shorter time period than I expected. For such a large project, this felt like the easiest one I’ve had to undertake so far thanks to Stuart, Jake and his team. We did shop around with 4 other competitors and these by far have the best reputation and I’m glad I trusted the reviews. 5* Thanks Team!!!”

Average rating: 5 out of 5 stars16 March 2022
“It is with huge pleasure that we provide a high recommendation for Paragon. They added a master bedroom, en-suite, walk in cupboard, loft conversation and rear extension to our existing home. From the beginning we felt very comfortable with Paragon's approach. They really listened to our brief and provided excellent advice. The final design was outstanding. The management of the design, consent, contract and construction process was seamless and stress-free with clear instructions from the team at Paragon and very little effort required from us. Their professionalism shows in management, quality of work and customer service. Our experience has been an extremely very positive one. Working with a team that is accommodating and sensitive to our needs. What a concept!”

“I have undertaken many projects, and Homeconcepts is the one company that I can honestly say was a joy to work with. They have the winning combination of highly professional management and a superb building team. No need for ‘snag lists; there are none. I am hoping to do a complete renovation next year and would not dream of looking anywhere else. Alan Bowie, East Molesey.”

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 London.

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.
