Glass Pavilion | 3.71m x 3.71m | Pool Room & Garden Pavilion | Aluminium Sliding Doors | Fully Installed Across Mainland UK
This glass pavilion is a compact, light-filled outdoor room that punches well above its footprint. At 3.71m x 3.71m with a 13.16m² indoor floor area, 44mm Nordic spruce massive log construction, a clean flat roof, and full-width aluminium sliding doors on two elevations, this is a building defined by glass, light, and connection to the outdoors. As a pool room, a garden bar, a garden office, or a year-round relaxation space, it delivers a premium feel that belies its size.
The door configuration is what sets this pavilion apart. Two sets of aluminium sliding doors — a 360cm x 206.7cm pair and a 200cm x 206.7cm pair — open the building on multiple sides, dissolving the boundary between inside and outside. On a warm day, slide them all back and the pavilion becomes an open-sided garden room. On a cooler day, close them and the double-glazed glass holds the warmth in while keeping the view completely unobstructed. This is a building that works with the seasons rather than against them.
The price shown includes the full supply and professional installation of your Glass Pavilion anywhere on Mainland UK, including the base preparation and installation and the complete construction of the structure. There are no hidden costs and no separate groundworks quotes. What you see is what you pay.
For locations outside of Mainland UK — including islands and certain remote areas — please contact us for a tailored delivery and installation price before ordering.
Precision Built, Beautifully Finished
44mm Nordic spruce massive log construction gives this pavilion a solid, well-crafted feel that distinguishes it immediately from lightweight garden structures. The flat roof profile keeps the building low and unobtrusive — a clean, contemporary silhouette that complements modern garden design without competing with it. The roof spans 431.6cm x 431.6cm with a ridge height of 256.5cm, providing a comfortable internal height throughout.
The natural untreated Nordic spruce finish is supplied ready for your preferred exterior treatment — stain, oil, or paint — or leave it to weather to a natural silver-grey patina over time. The floor is included as standard. The building arrives as a precision-engineered kit and is installed by our own team from foundation to handover.

How does the door configuration work?
The pavilion features two sets of aluminium sliding doors — a 360cm wide set and a 200cm wide set — positioned on different elevations. Both sets are 206.7cm tall and double-glazed. When fully open, they create a near-seamless connection between the interior and the garden on multiple sides.
Do I need planning permission?
In many cases a building of this size will fall within Permitted Development rights for residential properties in England and Wales, provided it is used as an ancillary garden building, is sited within the curtilage of a dwelling house, and does not cover more than 50% of the garden area. We always recommend confirming with your local planning authority before ordering.
What does the natural untreated finish mean?
The building is supplied in its natural Nordic spruce finish — untreated and ready for you to apply your preferred exterior stain, oil, or treatment. We can also supply and apply an exterior treatment as an optional upgrade.
How long does installation take?
Typically one to two days, depending on site conditions and foundation type. We will confirm the installation schedule with you in advance.
How long does delivery take after ordering?
Typically 4 to 8 weeks from order confirmation. Please contact us if you have a specific deadline.
