Ale&G - Design Solutions
House Extension Professionals in London
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).”
MODEL Projects Ltd
House Extension Professionals in 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 London.

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.
