Addition – A projecting structure, or wing, which is part of the original building rather than a subsequent extension.

Apex – Two wooden sections meet at the highest point to create an upturned ‘V’ shape.

Bearers – Bearers are pressure treated posts which run in opposite directions to the floor joists making a criss-cross formation providing sturdy support and allowing good air circulation.

Cedar Shingles – Cedar shingles are used as a roof covering. Made from Western Red Cedar they come in random widths, each shingle is nailed in the middle of the shingle, into treated tile battens.

Eaves – The lower edge of a roof.

External Cladding – On garden rooms the external cladding is commonly made from wood, the wood used is shaped into different profiles such as tongue & groove, shiplap, tapered weatherboard and board & batten.

Finial – Covers the join of the apex where the barge boards meet and adds a decorative feature to the shed.

Gutter – A channel along the eaves of a roof or the edge of a path for the removal of rainwater.

Hipped Roof – A hipped roof is a roof with a pitched slope on all four sides of the building. The pitch of the slope is the same on each side. The point where the slopes intersect is called the hip.

Lean-to – A structure, the sloping roof of which abuts a higher wall.

Louvre – Slats laid at an angle incorporated into a door or window. Can be hinged to allow ventilation/light.

Pavilion – a part of a building that projects outward from the rest, or the detached or semidetached units into which a building is sometimes divided.

Pent – A single sheet of wood that slopes from the front of the building to the back at an angle. Ideal for buildings that are situated against a fence or wall, or is going to be tucked under overhanging branches.

Pressure Treatment – preservative forced deep into the heart of the wood and the grain structure under vacuum pressure. In effect, the preservative becomes an integral part of the timber giving it a long life and effective protection against rot.

Shiplap – Shiplap is a type of external cladding; it gets its name as its profile is used on wooden boats. Shiplap has a scooped top which slots into a groove at the bottom of the piece of wood above.

Skylight – A window set into a roof slope.

Tongue & Groove – The interlocking of the thicker boards leaves no gaps and means that the shed is better protected from draughts and rain – essential if you spend many hours in there.

Toughened Glass – The glass is manufactured to BS6206 and will shatter as opposed to splinter therefore reducing potential injury.

Overhang – The dimension of which the roof overhangs the main structure of the building, this can be in any direction and should be especially noted when space is limited, for instance if you plan to site the building next to a wall sometimes the overhang can mean it is prohibitive.
