Heavy-Duty Timber Protection: The Sloten Carport
Protect your car, van, or motorbikes from harsh British weather, falling leaves, frost, and UV paint damage with the Sloten Larch Douglas DIY Flat Roof Carport (3.5 x 5.0 m). One of our most popular timber shelters, the Sloten provides 17.5 square metres of dependable, heavy-duty overhead cover while adding natural, rustic charm to your driveway or garden.
Beyond vehicle protection, its generous proportions make it equally effective as a covered outdoor dining canopy, sheltered hot tub gazebo, garden workshop, or bicycle and trailer bay.
Flexible Installation: Freestanding or Lean-To
The Sloten offers complete installation versatility to match your driveway layout:
- Freestanding: Erect using all six 15 x 15 cm timber posts anywhere across your drive, lawn, or patio.
- Lean-To / Wall-Mounted: Anchor one side directly to a suitable house or garage wall using wall-plate fixings, using the remaining uprights along the open driveway side.
Chunky 15 x 15 cm Douglas Fir Uprights
Stability and wind resistance begin with substantial timber mass. The Sloten stands on six solid 150 x 150 mm (15 x 15 cm) square posts (2.50 m length), reinforced with diagonal storm braces. Sourced from slow-grown European Larch / Douglas fir, the timber is heartwood-rich, fine-sawn, and naturally resilient against damp, fungal growth, and decay.
Solid 18 mm Boarded Flat Roof
Unlike budget carports that rely on noisy plastic sheets or thin OSB boards, the Sloten features solid 18 mm double-lip tongue-and-groove timber roof boarding supported by structural purlins and finished with smart perimeter fascia boards. This substantial roof deck dampens rain noise and provides a rock-solid platform for high-performance waterproofing.
Modular DIY Timber Kit
Supplied as an adaptable Do-It-Yourself (DHZ) timber kit, the Sloten is intended for confident DIYers, carpenters, and landscape contractors. Structural timbers are supplied slightly over-length to be trimmed to final size during assembly, giving you the flexibility to adapt to existing ground slopes, driveway paving, or wall heights. The package includes:
- 6 x 15 x 15 cm fine-sawn Douglas posts (2.5 m length)
- Roof purlins, perimeter fascia boards, and diagonal braces
- Solid 18 mm double-lip tongue-and-groove roof boards
- Complete metal fixing hardware pack (screws, bolts, and fasteners)
- Clear, comprehensive assembly drawings
Recommended Accessories & Upgrades
- Roof Covering (Required): The carport is supplied without roof covering as standard. We strongly recommend selecting our premium EPDM rubber membrane kit with contact adhesive for a seamless, 50-year UV- and tear-resistant waterproof seal, or self-adhesive Easy-Roofing foil.
- Drainage: Pair your roof with a round EPDM roof drainage outlet and downpipe kit to channel rainwater away cleanly.
- Ground Anchors: For maximum longevity and to keep timber ends above ground water, mount the six uprights onto adjustable concrete post anchors (betonpoeren) bedded in fast-setting post-mix cement.
- Enclosure Walls: Convert your carport into a sheltered car port or private garden room by cladding one or more bays with our matching black or natural Douglas tongue-and-groove boards or Swedish feather-edge profile cladding.
