Alchemy Build
House Extension Professionals in Islington, Greater London
Average rating: 5 out of 5 stars14 March 2023
“Alchemy build have completed several projects for us over the years. Aaron and his team have always been communicative, professional and easy to work with. Our extensive home refurbishment was completed within the agreed timescale. Aaron offered us honest advice and suggestions throughout the project based on their experience and expertise. Sometimes this meant adjusting plans to avoid pitfalls down the line, which in hindsight saved us a fortune. Aaron also made us aware of some aspects of the project we were spending unnecessarily on, allowing us to re-evaluate our budget allocation. Ultimately, the team went over and above and exceeded our expectations. We received compliments about the house from friends and family, many who have now gone into contract with Alchemy to carry out their home renovations following the work they completed for us. I’d recommend to anyone looking for reliable, efficient and quality work.”

Aspen Design & Build
House Extension Professionals in Islington, 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.”

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 Islington.

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.
