Average rating: 5 out of 5 stars3 April 2021
“We used Urban Living for our full renovation. We met with Rafal and immediately connected and as this was our first building project we found this really helpful. We were provided a competitive quote and then followed up several references so we could see his team’s work. Once the build got underway we dealt with Rafal on a daily basis. The whole team were hard working and professional, and this was also recognised by our neighbours who gave positive comments about them. We are happy to recommend them and would use them again in the future.”

Aspen Design & Build
House Extension Professionals in Lewisham, Greater London
Average rating: 5 out of 5 stars6 January 2021
“I used Aspen for our project, it was our second move from a flat to a house. We bought a house which required a complete refurbishment, in addition we decided to extend the property to the rear along with a loft conversion. The works took 8 months to complete as the entire house was gutted along with front and rear garden landscaping. Aspen were exceptional to work with from start to finish, very accommodating with some additional alterations which we decided to carry out during the build. We would highly recommend Aspen especially as no compromise was taken with our previous home.”

“Inscope Management carried out the refurbishment/building work for a recent interior design project for a large apartment in Chelsea. This included a new bathrooms and kitchen (their speciality). Their work was of a high standard and their professionalism, pleasant & considerate behaviour worked well, in this potentially difficult and dense site with many occupied apartments around. They worked within designated times, and cleared and cleaned the communal access areas each day. Very pleased with their performance.”

Average rating: 5 out of 5 stars12 January 2021
“Crown Point Builders did an excellent job for us in replacing a odd shaped shower cubicle that was very old and leaking to the flat below. Ben was quick to respond to our initial enquiry, promptly visited the property to view the work and gave as a quote. He gave us a time frame for starting and completing the work which he stuck to. All our questions were dealt with quickly. The work was done to a high standard and we are delighted with the new shower. We would highly recommend Crown Point Builders.”

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 Lewisham.

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.
