“Jon and Beth were invaluable in helping us get the most out of the space we have in our home. They spent time listening to our ideas before making suggestions of their own. Their plans and ideas have been so helpful when speaking to builders and their experience in the field means that their ideas are achievable within a set budget. We would have no hesitation in recommending their services to anyone looking to extend or remodel their home.”
Studio Schubert

Average rating: 4 out of 5 stars18 July 2016
“We worked with Marek on 3 flat modernisations on the Hyde Park Estate and always found him to be both responsive and professional. The modern styling was along the lines we have used previously with our interior designers and completed to a very good standard. Susan worked with us to supervise a couple of ongoing projects which were experiencing delays and with her assistance we were able to get these completed to a good standard thanks to her professional approach.”
Randa Kort Interior Architecture & Design
House Extension Professionals
Average rating: 5 out of 5 stars2 January 2022
“We were a little wary about signing up an interior designer for our extension project because most of the other professionals we used seemed to over-charge and tended to cease involvement as soon as they were paid. But Randa was different and undoubtedly the best value of any of the the professionals we used. To begin with she solved a problem with the interior walls that immediately saved us hundreds of pounds and overall she took the extra time and effort to see the project and her ideas through to completion. She was generous with her time, included a design for our kitchen even though that was not part of her remit and answered our questions promptly when we needed her advice. She also kept an eye open to make sure the builders weren't taking short-cuts and generally seemed to care. Some of her choices were good money-savers, sometimes her suggestions were too expensive for us but she was happy to recommend something different if it was not within budget.”
Absolute Project Management
House Extension Professionals
Average rating: 5 out of 5 stars6 March 2017
“We worked with Absolute Project Management on a rear garden design following an extension they had recently completed. They met us on site with the clients for an initial meeting and discussed the arrangements & schedule of the project. Liz was our point of contact throughout the project, which allowed us to discuss any issues and questions with her. She answered our queries swiftly and easily and was in constant contact with the clients, which made us feel confident in the work. APM made regular visits throughout the project to check that everything was running smoothly and we are very pleased with the result. We would definitely recommend working with Absolute Project Management for all projects, as they are able to streamline and simplify the process for both the clients and the contractors.”

“An excellent finish to my bathroom. A few structural problems occurred due to bad workmanship in the past, but all the problems were sorted out at little extra cost to me. All work was completed on time and all the workers were very punctual, tidy and trustworthy. Would recommend the company to anyone who wants a good job done for a reasonable price.”
Nine Lives
House Extension Professionals
Average rating: 5 out of 5 stars2 February 2024
“Nine Lives and Philippa were wonderful at making my house feel more like a home. We did not live in all of our rooms downstairs as we were not sure how to use them. Philippa came and quickly worked out the best use of space to allow flow in our home. She is great at picking out colours and textures and finds material and wallpaper that I would never have been able to contemplate. Everyone that comes into our home always asks questions about the wallpapers and the fabrics we used. I am really thankful to Philippa for her hard work and attention to detail. We will go back for more advice in the future.”
Salvatore Fabio

Average rating: 5 out of 5 stars9 November 2023
“I had the pleasure of working with Salvatore during the renovation of my apt in Amsterdam. He has been an invaluable source of help and creativity, working his magic remotely during the pandemic, no less. Even though I have used his consultancy services from a distance, Salvatore was present and attentive, helping with design decisions that addressed my work from home needs as well as my pet's comfort and habits. I warmly recommend Salvatore for projects of all sizes!”

Interior 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.

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.
