Gentoo have delivered some striking new build social and affordable housing in Sunderland. The new development on Chaffinch Rd has used a combination of Old English Dark Red & Smooth Grey Edgemere Concrete Interlocking Slates for roofing which achieved a modern and contrasting look. Gentoo chose to use Edgemere Concrete Slate as it blended with the natural slate in the surrounding area and was an affordable alternative to standard interlocking tiles.
