Go Plans
House Extension Professionals in Chelsea, Greater London, UK
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 Chelsea, Greater London, UK
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.”
Trevor Brown Architects
House Extension Professionals in Chelsea, Greater London, UK
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.”
CATO creative
House Extension Professionals in Chelsea, Greater London, UK
Average rating: 5 out of 5 stars19 February 2015
“CATO creative have designed and project management our house refurbishment. They've literally done everything for us and have designed a fantastic family home that considers everybody including the cats. Right from the start the level of creativity and imagination has they have shown has been fantastic. I never imagined that we've have fairground lights in the loo, a metal staircase to the loft and a gloss red staircase in the hallway - We have! Throughout the process they involved us fully in the fun bits and left us out of all the hard work. They took care of all the planning and permissions required to start the works. To find a builder the team completed a tender for us helping us appoint the right contractor. During the build they managed everybody making sure it all happened at the right time. Hopefully the photographs will be shared soon.”
MODEL Projects Ltd

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.”

Average rating: 5 out of 5 stars24 May 2017
“I photographed Bernard's remodelling and interior design of a flat in North London. The work on show and Bernard's approach to the shoot demonstrated his eye for design, his attention to detail, and his very pleasant and professional attitude. He has a background working on big-budget international projects, which is evident in his meticulous approach, but as someone to work with he remains down to earth, approachable and collaborative.”

“I worked with JF Projects on a couple of projects and Jonathan is great at getting things done on time and within budget. He provides solutions which has brought us a lot of savings. He gets the liaising done between the Client and the Design Team so that we can just get on with the work. He also looks out for issues with the project before they arrise so that they do not slow the job down. I would recommend working with him and his team.”

“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.”

“I commissioned Ben to work on my ambitious extension project based on a very positive referral from a friend who had previously commissioned him. Ben immediately added value by identifying opportunities and enhancing the ambition and design of what I had in mind, whilst being responsible with the budget. Ben is a consummate professional, highly creative with a very thorough approach to the project that inspires confidence. Would highly recommend for any project size and complexity.”

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 Chelsea.

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.
