Elevate your property's kerb appeal and outdoor living space with a mortise and tenon green oak porch, pitched front extension, or year round insulated cedar garden room.
Turnkey Domestic Craftsmanship
Exterior architectural carpentry is where traditional master joinery truly shines. From heavy section green oak entrance canopies pegged with traditional timber dowels over brick dwarf walls, to enclosed front porch extensions and insulated western red cedar garden rooms, we craft exterior structures built to weather beautifully for decades.
We also combine front porch builds with integral garage conversions and driveway upgrades, turning cold storage space into a warm home office, playroom, or welcoming entrance hallway.
Technical Build Specification
Heavy section structural oak timbers cut and jointed by our master joiners, mounted on masonry plinths or staddle stones to prevent moisture wicking.
Damp proof membranes, insulated floating timber or screeded floors, toothed in front masonry or K render infills, and upgraded consumer unit circuits.
Concrete base or ground screw foundations, insulated timber frame walls and roof, breathable membranes, cedar cladding, plaster skimmed interiors, and armored mains power.
Complete external finishing including porcelain paving, composite decking frames, recessed deck lighting, and front driveway improvements.
Tailored To Your Property
Every structure is custom built on site to complement the brickwork, render, and roof pitch of your home.

“Came in bang on budget and the house looks amazing inside and out.”
“Chose ATD Joinery to project manage my 3 part complex extension project as Stephen Flinn made me feel confident in his experience and previous work. Do not regret that decision for one minute. Stephen and team were able to overcome challenges with a smile and came in bang on budget. The work has been excellent, house looks amazing inside and out.”
