“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!”

“To set the scene : we are mid-way through construction, to renovate & extend of our Victorian terrace in East London. We've had Seán and Stephen Ltd as our architects for 18 months so far. My wife and I are complete novices to design & construction, and Seán and Stephen have expertly and supportively guided us through each stage, enabling us to really enjoy every part of creating our new home. I would happily recommend this professional practice to family and friends. They were great at helping to bring some of our own design preferences to life using plans, 3D models, and interactive virtual room design tools. But they also have challenged our thinking too, leading us to add in a number of amazing and creative features that we would never otherwise have considered. Seán and Stephen created an extremely thorough and professional Design & Access Statement to help explain our project to the local planners. As a direct result of the quality of S&S’s planning pack our application (which proposed various potentially contentious items such as a basement, lightwell, and dormer) was approved without a single significant amendment. Since the contractor began the works Seán and Stephen have project managed every aspect of the construction programme, providing us with detailed weekly updates and explaining everything to us in layman’s terms. They consistently fight our corner with the contractor on a number of technical and cost-related issues which gives us real confidence that the project is in safe hands. So far we have enjoyed a stress-free project thanks to their project management skills”
Go Plans
House Extension Professionals in City of Westminster, 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.”
Wellstudio Architecture
House Extension Professionals in City of Westminster, Greater London
Average rating: 5 out of 5 stars28 January 2022
“Whilst project co-ordinating a refurbishment, I recommended Tom's practice Wellstudio architecture to my interior design studio's clients, a young creative family who were interested in undertaking an extension on their four story East London townhouse during the full scale renovation of their property. As the clients are lovers of art, we were keen to create a unique art led structure that was a little different, even unorthodox. The result was an origami inspired copper clad extension and garden canopy that's visual simplicity belies its technical complexity. This is where Tom really displayed his excellence as an architect, as he has both the artistic vision and collaborative character to flesh out conceptual forms that are genuinely original, but crucially, he also has the communication skills and technical rigour to bring it all to fruition with professionalism and diligence. I have no hesitation in recommending Tom for clients looking for an architect who can create something highly personalised to their needs and aesthetic.”
Studio SB

Average rating: 5 out of 5 stars22 May 2023
“Our family is totally new in London. We bought an interesting 3 bed flat, above 20/F, besides River Thames on one side and overlooking a dock on the other side. The flat is quite new and ready for living in. We however want to have better use of the space while maintaining or even highlighting the character of the flat, we decide to look for an experienced designer from various internet referral platforms. I notice that there are a lot of highly qualified interior designers and architects available out there. After over one month of selection process, we finally decided with confidence to go with SB Studio. We choose See Beng not only because of his impressive portfolio in architectural work and interior design but more importantly is his eagerness and patience to learn our expectation. We have gone thru one month of work together. It is very fulfilled experience. See Beng listens to us patiently to learn the details of our need. In the meantime, he would always provide ideas that we never think of. I can say it is a very harmonious cooperation experience. We contract SB Studio for design and project management. We have expectations of work quality, time control and budget control. See Beng’s resourceful connection in the field provide us more alternatives in terms of style and price. In order to meet time lines, See Beng would work for us during weekends or holidays, when really required. My wife and I are so happy that we have chosen See Beng as our interior designer and project manager.”
The Market Design & Build
House Extension Professionals in City of Westminster, 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.”

MODEL Projects Ltd
House Extension Professionals in City of Westminster, 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.”

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 City of Westminster.

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.

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.
