“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!”

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
Luxury House Extension Professionals in London Rated 5 Stars Only
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.”

“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.”
Superfusionlab Architects
Luxury House Extension Professionals in London Rated 5 Stars Only
Average rating: 5 out of 5 stars10 November 2017
“Superfusion were excellent! Their professionalism and work ethic is incredible, but the most impressive aspect of their work is their creativity and how this translates into a design solutions focused towards the benefit of their clients. In our case, they came up with the most brilliant ideas to make the most out of our very limited budget, the selection of materials in tandem with the design details gave a final result that was beyond what we imagined and looked as if we have spent 3 times more than we actually did. We are really looking forward to work with Superfusion for our next project, as we cannot wait to see what they can do with a much bigger budget.”

“Alessandra supported us with our kitchen renovation. She spent with us half day at Magnet to design our kitchen, select the materials and the colours. She was very careful and detailed oriented to make sure the kitchen we were getting was exactly what we needed/wished for. Important to note that Alessandra is open find solution for what you need/wish for (different from other architects who wants to put their mark and leave their “stamp” in their designs). She did delivered not a kitchen, but what we called a master piece of art - her careful selection of colour and materials + solutions to corners and panels at the top/at the bottom to hide electrics paid off having her in that work. Everyone who comes to our house or lastly who sees our kitchen from Zoom/Skype or Team spots how beautiful it is (not only beautiful, but for us who uses the kitchen it is entirely functional, easy to clean and all sorted). Thank you Alessandra - you made us very happy and ensured lockdown could be easily managed with our new lovely and super functional (easy to clean) kitchen! Before Alessandra - red kitchen. After Alessandra - the modern, atemporal grey/blue kitchen (please see pictures).”

RHJB Architects
Luxury House Extension Professionals in London Rated 5 Stars Only
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.”

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.
