Featured Reviews for House Extension Professionals in Sunderland, Tyne & Wear

RAR Architectural Services
House Extension Professionals in Sunderland, Tyne & Wear
Average rating: 5 out of 5 stars29 July 2026
“We were put in touch with RAR by our builders, having had no previous experience of engaging and working with an architect. As it turned out, we could not have chosen a better firm to work with. Alastair communicated clearly through the process and was responsive to answer any queries we had. We were impressed by the attention to detail which Alastair demonstrated, and his his assistance in specifying materials. We would also commend Alastair's flexibility when a change of direction in our house renovation prompted a substantial re-working of the design drawings which had already been completed. Finally, Alastair successfully managed our Planning Application for us. We would have no hesitation in recommending RAR Architectural Services.”

“My husband and I have been really impressed with ROK Architecture and with Adam’s attention to detail. His proposals for our kitchen and dining room extension were more than what we’d hoped for. We liked his approachable nature and his ability to explain the process to us in simple terms. We’d be more than happy to use ROK again in the future and recommend to others.”

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 Sunderland.

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.
