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!”

“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.”

“The most efficient and friendly staff, highly professional team that can execute your kitchen dreams and desires to an exact specification! The expertise that the team had from the inception with the detailed drawings with great design ideas and 3D visuals created by Sonya, and the level of detail from the installation manager Avtar who was on site during the process and the complete knowledge of every aspect of a kitchen from appliances, accessories, colour schemes and materials and the utilization of space from the directors Ajit and Sukh gave us clear confidence in their work and passion for the job and service provided. They were extremely personable, warm, friendly and charming and a complete joy to have been serviced by. The finished product has been complimented by every guest and is now clearly the highlight of our home. Would highly recommend to anyone looking for a great quality kitchen with fantastic service to go with it! Our family thank you Design Abode for realising our dream kitchen. One happy customer!”

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.”

Ale&G - Design Solutions

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).”
The Market Design & Build
House Extension Professionals in Harrow, 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.”

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 Harrow.

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.
