18′ x 8′ Traditional Heavy Duty Shiplap Apex Wooden Garden Shed (5.5m x 2.44m)
Overview
This 18′ x 8′ heavy duty apex wooden garden shed suits anyone who needs a long, workable space for storage, a workshop or a hobby room. Heavy duty shiplap cladding on a robust cross braced frame gives it real structural strength, while the traditional apex roof keeps everything inside dry and adds useful headroom.
Key Features
- 12mm tongue and groove shiplap cladding for weathertightness
- Heavy duty 50mm x 50mm smooth planed frame with diagonal cross bracing
- Lockable door with zinc hinges, door knob and rim lock
- Georgian style windows with toughened glass
- Generous interior headroom for comfortable standing access
- Diamond shaped finials for a traditional finish
- Flexible door positioning to suit your garden layout
Roof Types
The apex roof is built from 12mm tongue and groove timber and topped with premium mineral felt, giving effective water runoff and good headroom throughout the shed. If you need even more length, the 20′ x 8′ Traditional Heavy Duty Shiplap Apex Wooden Garden Shed uses the same construction in a slightly bigger footprint.
Dimensions
- Width: 5.5m
- Depth: 2.44m
- Footprint: approximately 18′ x 8′
Construction
The 12mm tongue and groove shiplap cladding is fitted to a robust 50mm x 50mm frame with diagonal cross bracing for extra rigidity, and the matching 12mm tongue and groove floor provides a solid, durable base. Every component is smooth planed for a neater finish and better long term weather resistance.
Treatment & Guarantee
The shed is supplied dip treated with a 1 year parts guarantee, excluding roof felt, and needs re-treating within six weeks of assembly and annually thereafter. Upgrading to pressure treated timber extends the anti-rot guarantee to 15 years and includes a free upgrade to extra thick 15mm cladding, though annual waterproofing is still required.
Doors & Windows
Access is via a sturdy ledged and braced door fitted with zinc hinges, a door knob and rim lock to keep equipment secure. Georgian style toughened glass windows bring in natural light, and both the door and windows can be repositioned, converted to opening, or removed entirely to suit your needs.
Assembly Information
Specification measurements for cladding, floorboards and framing are nominal before machining, with a variance of plus or minus 1mm on cladding and floorboards and plus or minus 5mm on framing, as is standard across the timber industry.
