Chunky Modern Luxury: The Renesse 4 × 3.13 m Gazebo
The Renesse 4 × 3.13 m (400 × 313 cm) delivers 12.5 square metres of dependable, heavy-duty sheltered living space. Designed with an overhang-free perimeter and a clean flat roofline, this compact pavilion fits effortlessly against patio edges, corner garden borders, or contemporary boundary fences.
Four Monumental 20 × 20 cm Glued-Laminated Posts
The defining feature of the Renesse is its immense framework. Supported by four chunky 200 × 200 mm (20 × 20 cm) laminated posts, the open four-post layout leaves all four sides completely accessible. With no middle posts to navigate, you have complete freedom to arrange a four-to-six-seater outdoor dining table, a corner lounge sofa, or a private 2-metre hot tub retreat.
The Red Class Wood Advantage
Crafted from kiln-dried Red Class Wood, this gazebo gives you the warm, organic aesthetic of Douglas fir with far superior dimensional stability. The timber is kiln-dried to eliminate warping and twisting, resin channels are stabilised to stop sticky sap bleeding, and the factory impregnation provides long-lasting defence against moisture, mould, and rot in British weather.
Boarded Timber Roof Construction
The roof deck features solid 1.8 × 19.5 cm tongue-and-groove roof boards carried by heavy 6.5 × 19 cm ring beams and 4.5 × 12 cm purlins. This thick timber roof dampens rainfall noise and provides a rock-solid, flat deck for EPDM waterproofing.
Customise with Modular Infill Walls
Enclose the back or sides to block prevailing winds and create a private garden sanctuary. Compatible DIY wall modules clad in matching Red Class Wood or factory-sprayed black feather-edge planks are available separately in the product options.
