Garden Party Room With Bar by Timber Rooms

When we ask homeowners what they are planning to build, a home bar and entertainment space comes up more often than you might expect. This project by Timber Rooms in Esher, Surrey, is one of the better examples we have seen of that idea completed to a high standard: a fully insulated garden room with bi-fold doors, a slatted timber feature wall, and a navy bar with marble top that gives the space the feel of a private members club.
It is also a repeat-client project, which says something in itself. The owners previously had a Timber Rooms garden office at their old property. Having lived with what a well-built garden room can offer, they came back when they moved house — this time with a different brief and the confidence to go further.
A Building Shaped Around the Site
The footprint is 6.5m x 5.3m, but the building is not a standard rectangle. The boundary line at the back of the garden runs at an angle, and rather than defaulting to a conventional shape and accepting the awkward wedge of land that would be left behind, Timber Rooms designed the building to follow the contour of the boundary instead.
It is a straightforward idea but one that requires a bespoke approach to deliver. A garden room chosen from a fixed range of sizes cannot adapt to a plot like this; a bespoke building can. The result here is that the owners use every metre of available space, with nothing wasted. Looking at the finished room from inside or out, you would not know the plan was anything other than a simple rectangle.
Four-Leaf Bi-Folds and the Indoor-Outdoor Connection
The front elevation is taken up almost entirely by a set of four-leaf bi-fold doors, which open the room out onto a terrace where there is a seating area with a fire pit. When those doors are open, the boundary between the interior and the garden dissolves almost entirely. When they are closed, the insulation in the walls, roof, and floor means the room remains comfortable for year-round use — helped further by an air conditioning unit that handles temperature control in terms of both heating and cooling.
The roofline extends beyond the front wall to form a canopy, which provides a degree of shelter to the entrance and creates a strong shadow line on the elevation. Exterior-grade LED lighting has been fitted to the underside of the canopy, so the building works as well after dark as it does during the day.
Thermo Ayous Cladding
Timber Rooms finished the exterior in Thermo Ayous, a thermally modified timber that is often seen as an alternative to Western Red Cedar. The modification process stabilises the timber and improves its durability, and the resulting colour — a warm, pale tone that weathers gradually — sits well against the anthracite grey door frames, windows, and trims. It is a material that reads as natural and considered rather than flashy, which is a good balance for a building intended to enhance a garden rather than compete with it.
The Bar and Interior Finish
Inside, the client's brief was clearly ambitious and Timber Rooms have delivered it in full. Timber Rooms plastered and decorated the walls and ceiling throughout, and the floor is laid in a laminate with a herringbone pattern, which adds more character than a straight-laid board would.
On the right-hand wall, slatted timber panelling creates a tactile feature wall. The bar itself runs along the rear wall in a dark navy finish with integrated fridges, and a large island unit with a marble top creates a natural social focal point in the centre of the room. The overall effect is closer to a smart hotel than the traditional vision of a garden outbuilding.
Lighting has been treated with the same care as everything else. Timber Rooms' in-house electrical team — operating under the TR Energy brand, which is NAPIT accredited — works with homeowners to plan socket positions, lighting placement, and controls around how the room will actually be used and where furniture will sit. In an entertainment space, that level of planning matters: the difference between lighting that makes a room feel right and lighting that does not is often a matter of positioning rather than specification.
