Featured Reviews for House Extension Professionals in Milton Keynes, Buckinghamshire

Prime Renovation & Construction Ltd
House Extension Professionals in Milton Keynes, Buckinghamshire
Average rating: 5 out of 5 stars23 February 2026
“We used Prime Renovation in 2024 for a major renovation, including a full rework of our main living space (a large living room with the dining area behind it) and other parts of the house. It wasn’t an easy job — lots of detail, panelling and finishes — but they handled it properly and the standard of workmanship was excellent. If I’m honest, out of everything we did, this living/dining room is my favourite part of the house now. The proportions feel right, the wall panelling and detailing are beautifully done, and the colours and overall look just work. It feels calm, elegant and finished in a way that you don’t get with a typical refurbishment. They were organised, respectful in the house, and communication was good throughout. We’re genuinely very happy with the result and I would absolutely recommend Prime Renovation.”

“Chris and Adam were very professional and helpful throughout the process of designing our porch extension and bedroom bay window seat extension. We live local to their offices and they came and visited, measuring carefully, and were extremely knowledgeable. Adapting the plans along the way was also super easy with the design software they were using. We had no issues at all and they were able to help suggest some local building companies to approach, as we decided to self-manage (it was a relatively small project). We would have no hesitation in recommending their services.”

Design and Build Company 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 Milton Keynes.

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.
