Featured Reviews for House Extension Professionals in Elstree, Hertfordshire

Shinz Design Consultancy
House Extension Professionals in Elstree, Hertfordshire
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!”

Ale&G - Design Solutions
House Extension Professionals in Elstree, Hertfordshire
Average rating: 5 out of 5 stars12 May 2021
“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).”
Design Spec Ltd

Average rating: 5 out of 5 stars15 April 2016
“Extremely pleased with the service we received from James at New World Designers Ltd. He couldn't have been more helpful, visiting us on numerous occasions to discuss what we wanted, offering ideas and suggestions and saying what was or wasn't possible. He also kept in regular contact throughout the whole process to keep us informed of what was happening. We will definitely be using them again and can't recommend them highly enough.”
Sheldon Peever Studio Ltd
House Extension Professionals in Elstree, Hertfordshire
Average rating: 5 out of 5 stars7 May 2015
“We employed Christine Peever to provide us with architectural services to renovate a 4 storey property dating back to 1912. The property was in a very poor state and we had no experience of such a project. Christine was an excellent listener to our needs and I felt she understood our strengths and weaknesses as her clients and adapted herself to us both as individuals to create our vision. Her note taking was faultless and she carried out all changes with exactness and efficiency, of which there were many! We also have to thank her for her endless patience during the decision making processes. She pushed us hard to make as many decisions as possible before going out to tender and this has inevitably assisted us with keeping our budget under control. We look forward to welcoming her back to the property shortly so that she can see what she helped us to create.”
Randa Kort Interior Architecture & Design
House Extension Professionals in Elstree, Hertfordshire
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.”
Go Plans
House Extension Professionals in Elstree, Hertfordshire
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.”

“We have worked with ACAA on refurbishment projects and garden designs in London for several clients. Andreas, Fabio and the team are very knowledgeable and always professional throughout. We would not hesitate to recommend them.”
Trevor Brown Architects
House Extension Professionals in Elstree, Hertfordshire
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.”

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 Elstree.

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.
