Built on Attention to Detail & Over Two Decades of Craftsmanship
From constructing luxury coastal homes in Australia to delivering high specification domestic extensions, dormer loft conversions, and bespoke kitchens across Liverpool, Maghull, Formby, and Merseyside.
Our Story & Heritage
Led Personally by Founder & Project Manager Stephen Flinn
Incorporated in March 2019 in Liverpool and registered in Maghull (Company No. 11904005), ATD Joinery & Construction Ltd was founded by Stephen Flinn with a clear purpose: to give Merseyside homeowners a construction and joinery firm where personal accountability, honest communication, and master finishing come first.
Stephen brings over 23 years of hands on industry experience, including years spent on the coasts of Australia constructing high end architectural homes designed around open plan living, natural daylight, and seamless indoor to outdoor flow.
Today, alongside Matt and our trusted team of time served tradesmen, we channel all of that experience exclusively into private residential projects across Liverpool, Sefton, and Merseyside.
The ATD Standard
Our Six Point Homeowner Charter
Inviting builders into your family home for an extension, loft conversion, or renovation requires complete trust. Here is what every ATD client can count on.
100% Domestic Homeowner Specialist
We exclusively build for private homeowners. We never pull our bricklayers, roofers, or joiners off your house to service commercial contracts.
Joinery Led Construction
Because our core trade is master joinery, our vaulted roof framing, dormer structures, shaker kitchens, herringbone floors, and media walls are finished to millimetre precision.
Direct Oversight by Stephen Flinn
Founder Stephen Flinn and Matt coordinate every stage of your build personally, keeping you informed daily on which trades are arriving and what milestone is next.
Itemised Stage Payment Milestones
Every quotation sets out a transparent written scope of works and a milestone payment schedule so you only ever pay as verified stages of work are completed on site.
Full Building Control Sign Off
We coordinate every stage inspection directly with Liverpool, Sefton, Knowsley, West Lancashire, or Wirral Building Control right through to your completion certificate.
Clean, Liveable Family Sites
Most of our clients live at home throughout the build. We build the weatherproof outer shell first, use zip sealed dust screens during knock throughs, and tidy the site daily.
