From site clearance and foundations to hand cut roofs and luxury interior joinery, Stephen Flinn manages your bespoke residential new build under one accountable contract.
Turnkey Domestic Craftsmanship
Commissioning a one off family home or self build plot requires a principal contractor who combines structural authority with an obsessive eye for finishing detail. Before establishing ATD Joinery & Construction in Merseyside, Stephen Flinn spent years constructing high specification coastal homes in Australia designed around natural daylight, structural precision, and indoor to outdoor living.
Whether you have full planning approval on an infill plot in Formby, Aughton, Maghull, or South Liverpool, we deliver the complete build programme: groundworks, masonry and steel superstructure, slate and zinc roofing, aluminium glazing, underfloor heating, and our signature interior joinery package.
Technical Build Specification
Site security, setting out, foundation excavations, poured concrete or piled foundations, foul and surface water drainage, and insulated beam and block ground floors.
Facing brick and insulated cavity blockwork, structural steel frames, crane installed floor joists, hand cut timber roofs, natural slate tiling, and green oak porches.
Anthracite aluminium windows, bi fold doors, sky lanterns, underfloor heating manifolds, plumbing and electrical first fix, insulation, and plastering throughout.
