Architectural Presence: The Renesse Red Class Wood Gazebo
The Renesse DIY Red Class Wood Flat Roof Gazebo brings clean, contemporary lines and immense structural character to British gardens. Built around massive 20 × 20 cm glued-laminated posts and designed with a flush, overhang-free roofline, the Renesse creates an immediate architectural statement on garden patios, modern porcelain terraces, or poolside decking.
Whether you want a sheltered garden lounge, an outdoor kitchen and bar canopy, or an all-weather hot tub cover, the Renesse provides superior structural mass, dimensional stability, and clean Scandinavian styling.
What Makes Red Class Wood Superior?
Red Class Wood is a modern engineered timber specially developed to offer the warm, reddish-golden beauty of traditional Douglas fir / Larch, but with significantly enhanced performance benefits:
- Kiln-Dried for Dimensional Stability: Unlike standard fresh-sawn or unseasoned timber that shrinks, splits, twists, and leaks sticky resin, Red Class Wood is kiln-dried before processing, ensuring straight, stable timbers that stay true.
- Specialist Eco-Friendly Impregnation: Treated with a high-performance preservative that penetrates deep into the wood fibres, delivering up to four times the lifespan of untreated Douglas fir in damp ground contact.
- Retained Warm Colour: Fades far more slowly and evenly than standard softwood, maintaining its attractive warm hue longer before silvering gracefully.
Substantial 20 × 20 cm Glued-Laminated Posts
Most timber pergolas use 12 × 12 cm or 15 × 15 cm posts. The Renesse steps up to colossal 200 × 200 mm (20 × 20 cm) laminated posts. Lamination prevents the large surface splits and twisting typical of solid green heartwood logs, delivering unmatched structural strength, rigidity, and architectural presence.
Solid 1.8 × 19.5 cm Boarded Ceiling
Overhead, the roof is boarded with wide 18 mm thick, 19.5 cm wide tongue-and-groove timber roof decking supported by heavy 6.5 × 19 cm ring beams and 4.5 × 12 cm purlins. This thick timber ceiling creates a clean, premium timber finish from below while deadening the sound of rainfall.
Customisable Infill Wall Packs
Tailor your Renesse shelter to your garden layout by adding optional side or rear wall modules (available separately in the extra options):
- Matching Red Class Swedish Feather-Edge: Complete horizontal overlapping timber walls in Red Class Wood for a uniform, warm timber look.
- Sprayed-Black Swedish Feather-Edge: Factory-sprayed black feather-edge boards for a striking, modern two-tone contrast against the golden timber frame.
Modular DIY Construction Kit
Supplied as an adaptable Do-It-Yourself (DHZ) timber construction kit, the Renesse is intended for confident DIYers, carpenters, and landscaping professionals. Timbers are supplied un-notched and slightly over-length to allow exact on-site trimming, ensuring the structure adapts seamlessly to your ground levels and paving. The package includes:
- 20 × 20 cm glued-laminated Red Class upright posts
- Heavy structural ring beams (6.5 × 19 cm) and roof purlins (4.5 × 12 cm)
- Solid 1.8 × 19.5 cm tongue-and-groove roof decking
- Complete metal fixing hardware pack (screws, bolts, and fasteners)
- Comprehensive assembly drawings and construction guide
Recommended Installation Notes & Accessories
- Foundation Anchoring: Mount each post onto straight concrete post anchors (betonpoeren) bedded in rapid-setting cement. Straight piers allow concrete gravel boards to sit flush without gaps when fitting optional walls.
- Roof Waterproofing (Required): Supplied without roof covering as standard. We strongly recommend selecting our heavy-duty EPDM rubber membrane kit with contact adhesive (add one can of spray adhesive per 5 m²) and aluminium or anthracite roof edge trims.
