Featured Reviews for House Extension Professionals in Mayfair, Greater London

The Market Design & Build
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars19 October 2016
“The Market Design and Build has just finished a big project for us and we couldn’t be happier. The property is an old converted barn so the challenge was huge. Obviously there were some set backs but the communication in between us (property owners) and The Market was excellent so problems were solved quickly. These guys are not here to screw you over. Before signing the contract they guaranteed us that they wouldn’t leave the project until we were 100% happy.. And they didn’t! We are sure to use The Market again if we need more work done on a property in the future.”
Go Plans
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars31 December 2022
“Our experience with Go plans has been excellent. They arranged a home visit at very short notice, listened to our suggestions and compiled the initial drawings relatively quickly. They also successfully handled the whole planning permission process for us and provided a very fast and professional response to the requests and changes requested by the planning officer. We would definitely use them again for future work.”
RHJB Architects
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars20 May 2016
“Designed a Garden Room extension to the back of a 1960s house in a 20th Century Conservation Area to create an 'integrated living' feel to the ground floor including taking the kitchen into this space. The Architects worked collaboratively with us, taking the design through the Planning process, producing detailed tender documents to enable us to select an appropriate builder. Remaining in the background but available to support us during the construction period.”
Callender Howorth Interior & Architectural Design
House Extension Professionals in Mayfair, Greater London
Average rating: 4 out of 5 stars15 December 2014
“Callender Howorth provided us with a full design and project management service for an extension and full refurb of our maisonette. They liaised with planners, architects, building contractors, kitchen companies and advised on sourcing of materials and interior furnishings. The project took 1 year from conception to completion. The people at CH were creative, professional and importantly a pleasure to work with. I would and have recommended them successfully to friends.”
MODEL Projects Ltd
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars17 January 2014
“Model Projects were a delight, from the initial brief with James who immediately took my requirements and turned them into a fantastic design - spot on first time with no amendments necessary. Kathryn then took over on a day to day basis as project manager and I cannot praise her highly enough. Dealing with the local authority, building control, structural engineers and the many contractors was done with calm and determination and I now have my dream space.”
Inter Urban Studios Ltd
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars6 October 2015
“We hired Inter Urban Studios to help us convert our loft into living space. The team was very professional, and added a healthy dise of out of the box thinking to an otherwise cookie cutter type project. Micah was always available to discuss things and provide advice and how to solve for particular results. We have recommended the services to our friends and would use them again if the opportunity arose.”
Francesco Pierazzi Architects
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars4 June 2014
“Innovative design ideas with precise attention to detail. FP provided a thorough service from design to project management (including liaising with builder throughout project; obtaining planning permission; managing payment schedules). Good source of knowledge and advice for furnishings and fittings. Some expensive tastes...! Very nice to deal with and would reccomend without any hesitation.”
Macro Micro Architecture
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars2 January 2024
“I have known Sebastian for many years, collaborating with him on projects across various sectors and scales. He is professional, polite and passionate about the built environment and quality customer service. I would recommend Macro Micro Architecture to anyone looking for a highly experienced architect that will endeavour to come up with something bespoke and unique for all of their clients.”
Trevor Brown Architects
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars14 October 2015
“Trevor Brown was a pleasure to work with. We started with a humble idea of replacing a structurally unsound kitchen with something a bit nicer, and he transformed the project into a fabulous piece of architecture. Trevor is knowledgeable, and has an ambitious attitude to even simple projects. By paying attention to both the structure and the details of the kitchen, Trevor created a space which is a beautiful space and also very functional. Trevor is a busy man, but he replied to emails, and answered the phone when we had queries. He worked well with the construction team and they were able to take a pragmatic approach to solving problems along the way. We exceeded the original budget, but that was at least in part because we chose more expensive options when Trevor offered us choices.”
Terrence
House Extension Professionals in Mayfair, Greater London
Average rating: 5 out of 5 stars17 May 2023
“I was very happy with the service that Terrence provided. They offer a very affordable service and drawings were turned around very quickly. Our house is in a densely built area and there were a lot of neighbours to consider. Terrence successfully navigated a complicated planning process that had lots of objections and were friendly and professional throughout the process.”

Architect or Architectural Designer 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 Mayfair.

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.
