“Great service from Mark, i would highly recommend anyone considering getting professional drawings for your house extensions to use Marlin Designs, not only did they delivered on time but on budget, Mark was always on the other end of the telephone to answer any queries you may have.

Go Plans
House Extension Professionals in 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.”

“HA have been a great help with our extension/ renovation and have helped guide us through planning, structure and building regs.

Working with Phil and the team has been great along with their honesty and advise it has made the project an enjoyable process. I would highly recommend HA !”
MODEL Projects Ltd
House Extension Professionals in 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.”
Jones Associates Architects
House Extension Professionals in London
Average rating: 5 out of 5 stars28 April 2015
“Chris completely redesigned the downstairs of our house and aspects of upstairs. He was very imaginative, which we really valued, coming up with ideas that we hadn't thought of. He clearly explained the pros and cons of each possibility, conscious of our needs and taking them into account. He had very good attention to detail eg re door handles and sometimes asked the builders to redo something if it wasn't right. He was reliable and kept to deadlines, meaning the project didn't overrun by too much. He was pleasant to work with and had a good relationship with the builders, which is extremely important. Obviously there are aspects that with the benefit of hindsight we might have done differently but overall, we were pleased with how the project went and we love our house.”

Average rating: 5 out of 5 stars26 July 2017
“Yihyi has helped our family on a couple of occasions, and both have gone so well that we intend to get her involved in a third project. We can't recommend her highly enough. She helped my brother turn a two bed one bath flat into a three bed two bath flat, creating a great family home from a small space, with flair and care - but without a huge budget. A couple of years later, she has helped me update my loft space and create a living and sleeping space that we absolutely love, and also reworked my bathroom, shower room and small toilet - all of which I love. If you get the chance to hire her - do it!”
Francesco Pierazzi Architects

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.”
VC Design Architectural Services
House Extension Professionals in London
Average rating: 5 out of 5 stars5 August 2014
“VC Design was recommended to me and I would do the same without hesitation. We contacted Veronica about drawing up plans for our ground floor extension and although conceptually we had a clear idea of what we wanted to she was invaluable in advising us how to best use the space and our options within the parameters of planning. She also contacted previous clients and arranged for us to see the work they had done, this allowed us to see first hand some of the ideas we had discussed. Veronica submitted the planning application and we have now received our approval - a job very well done.”
Trevor Brown Architects
House Extension Professionals in 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.”
Macro Micro Architecture
House Extension Professionals in 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.”

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 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.
