Design & build contractors across Warrington and the WA postcode area. Rear extensions, bespoke kitchens, loft conversions and full refurbishments — delivered to the same standard in Stockton Heath, Lymm, Grappenhall, Appleton and Walton.
Warrington is one of the most varied areas we work in. Victorian terraces in Latchford and Howley, 1930s semis in Appleton and Stockton Heath, 1960s timber-framed estates in Penketh and Great Sankey, post-war prefabs in Woolston, plus the large new-build estates ringing the town. Whatever the vintage, the build detail is usually the same story — decent bones, tired interiors, a kitchen stuck in the wrong decade, and space that could be opened up.
We\'ve worked across every Warrington postcode, know which streets have which structural quirks, and know how to budget for the "surprises" that come with older houses in a way that doesn\'t blow up when we open a wall.

The questions we're asked most often by Warrington homeowners.
We cover the whole WA postcode area — Stockton Heath, Appleton, Grappenhall, Lymm, Walton, Thelwall, Latchford, Fearnhead, Woolston and Birchwood. Same standard, same team, wherever the property is.
Yes — both dominate the Warrington housing stock, and both have distinct quirks. 1930s semis typically need joist-end repairs and rear DPC investigation before any extension work. 1960s estate houses often have timber-frame construction that needs checking before knock-throughs. We survey all of this at the free site visit.
A typical single-storey rear extension with a new kitchen in Warrington runs £70,000–£140,000. Higher-spec installations with bespoke kitchens, large bi-fold glazing and stone flooring push £140k–£220k+.
