Shinz Design Consultancy

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!”

“Callender Howorth provided us with a full design and project management service for an extension and full refurb of our maisonette. They liaised with planners, architects, building contractors, kitchen companies and advised on sourcing of materials and interior furnishings. The project took 1 year from conception to completion. The people at CH were creative, professional and importantly a pleasure to work with. I would and have recommended them successfully to friends.”

“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.”

“I worked with JF Projects on a couple of projects and Jonathan is great at getting things done on time and within budget. He provides solutions which has brought us a lot of savings. He gets the liaising done between the Client and the Design Team so that we can just get on with the work. He also looks out for issues with the project before they arrise so that they do not slow the job down. I would recommend working with him and his team.”

RHJB Architects

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.”

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 City of Westminster.

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.
