“Very happy with my extension! Brits are a professional company and very accommodating. The team are polite, reliable, tidy and more than happy to make changes along the way. A great standard of work -- I've even had them to landscape the garden and now they're doing the main bedroom! Would have no problem recommending them.”

“Extention work completed on time and agreed budget. The quality of work has been very good. Ali was always available to disucss any issues and the guys were flexible to accomodate any last minute small changes (which are inevitable for any build project). I will recommend and also use them again in the future.”
Vikram, HA1 · Harrow
House Extension · Jun 2014
“I have just had a garage conversion and rear extension to garden via a bifold door, with a steel framework completed by Brits. As part of the work they also had to extend the central heating system and fully wire the area. The quality of work has been very good, the tiling work is excellent and the general finish is great. The workers have been reliable, clean and efficient and the project has been completed to the price agreed. Overall an excellent service and I will use them again in the future.”

FAQ
Building in Harrow: your questions
Yes. We work across Harrow, including Harrow on the Hill, Pinner, Stanmore, Wealdstone, Kenton and Rayners Lane, covering the HA1, HA2, HA3, HA5 and HA7 postcodes. It is about 2 miles from our Harrow office, so surveys and site visits are easy to arrange.
Harrow has 30 conservation areas, grouped around Harrow on the Hill, Pinner, Stanmore and Edgware, and Harrow Weald. Many of them also have Article 4 directions, which remove some permitted development rights, so more work needs planning permission there. Applications here are decided by London Borough of Harrow.
Yes. Our portfolio includes patio & landscaping in Harrow. 9 homeowners with HA1, HA2, HA3 and HA5 postcodes have left verified reviews of our work, between 2013 and 2022.
Possibly: Harrow has 30. The ones most likely to affect an extension are the Article 4 areas, such as Harrow on the Hill Village, Pinner High Street, Stanmore Hill and Canons Park Estate, where even small alterations can need planning permission. Rayners Lane, Eastcote Village and Sudbury Hill are conservation areas without an Article 4 direction. We check your address against the council's maps before any design work starts.
