Eight disciplines, one team, one point of contact.

  • Extensions

    Single and double-storey, side-return and wrap-around, matched to the existing house so it reads as always-there.

  • Loft Conversions

    Dormer, hip-to-gable and Velux: a proper room, not an afterthought in the roof.

  • Kitchens & Living

    Open-plan rear extensions and full kitchen renovations, from strip-out to the last bit of trim.

  • Bathrooms

    Bathrooms and en-suites, tiled and finished to last, including loft and awkward-space installs.

  • Garage Conversions

    Turning dead garage space into a warm, usable room that matches the rest of the house.

  • Full Renovations

    Whole-home refurbishments, managed end to end by one team on one programme.

  • Roofing

    Re-roofs, repairs, flat roofing and leadwork, our Signature Roofing division.

  • Driveways & Landscaping

    Driveways, patios, walls and garden works, our Bespoke Landscaping division.

    Couldnt recommend this building company enough. 10 stars! I was horrendously lied to by previous contractors who did a cowboy job and charged me for shoddy work. If you’re looking for good, honest and hard working builders you can genuinely trust, look no further.

    I had an emergency with my roof and Scott and his team got straight out to sort it, which I really appreciated. From the start everything was well organised and handled quickly. Every question I had Scott was straight back to me, which made the whole situation a lot less stressful for me.

    I first saw Gray’s Signature Builds recommended on Facebook and decided to book a free consultation. From start to finish, the whole experience was smooth and professional. The loft conversion was completed within the timeframes they gave me, with minimal disruption throughout.

    From start to finish, my experience with Scott and his team has been outstanding. They handled my extension and new kitchen with incredible efficiency and care. Every member of the team was friendly, respectful of my home, and always left everything tidy.
