Pitched roof granny annexe

Most annexes take a shallow mono-pitch. This one has a 3.5m ridge and a vaulted ceiling over 31.2 sqm — a rendered garden cottage for a gentleman living independently beside his family.

Annexe Spaces  31.2 sqm under a 3.5m ridge

If you explore our archive of self-contained granny annexes, you’ll notice that most of them feature shallow mono-pitched roofs. However, specialist companies like Annexe Spaces also offer the option of a dual-pitched roof, which adds character to the exterior while providing a stunning interior with vaulted ceilings that create a light, airy atmosphere.

This recent project by Annexe Spaces is a perfect example. At 31.2 sqm, it may be compact, but the high ceilings make the space feel much larger. Designed to provide independent living for a gentleman while allowing him to stay close to his family, this annexe combines functionality and style.

Annexe Spaces offers a bespoke design service, working closely with clients to tailor the layout and room sizes to suit their specific needs. They also provide a full turnkey service, managing the entire project from initial design to final decoration. Unlike some companies, Annexe Spaces’ service includes all necessary groundwork for plumbing and electrics, as well as final connections to the mains supply.

Their project management service also handles the planning approval process and ensures that every stage of the build is signed off by Building Control.

At a glance

  • Size: 8.37m x 4.39m, 31.2 sqm, with a ridge height of 3.5m — the vaulted ceiling is what makes a compact plan feel bigger.
  • The roof: pitched and tiled in Metrotile rather than the shallow mono-pitch most granny annexes use.
  • Layout: a living room with a well-equipped kitchen along the rear wall and doors onto the garden, with the bedroom off the main space, also facing the garden.
  • Outside: cream render chosen to match an existing garden building, with dark grey doors, windows and trims against it.
  • The service: bespoke design and a full turnkey build, with the planning approval and every Building Control stage handled by the company.

Outside

Contemporary garden cottage

Externally, this annexe evokes the charm of a country cottage. The building’s exterior is rendered in a cream colour chosen to match an existing garden building. Dark grey doors, windows, and trims add a sharp, contemporary contrast.

The roof is tiled with Metrotile, known for their durability and maintenance-free lifespan, which can last several decades. Together with the render and uPVC doors and windows, these materials ensure the family won’t have to worry about maintenance to keep the annexe looking its best.

Layout

One-bedroom garden home

The annexe has a footprint of 8.37m x 4.39m, with a ridge height of 3.5m at its highest point.

The layout features a spacious living room with a well-equipped kitchen along the rear wall. The combination of doors opening onto the garden and the vaulted ceiling gives the living area a bright, open feel. A door from the main living space leads into the bedroom, which also overlooks the family garden. The bedroom includes an en-suite shower room, providing convenience and privacy.

A tidy build

Construction phase photos offer valuable insight into the building process and showcase the attention to detail the installation team maintains while on-site.

The Annexe Spaces team takes pride in keeping their work area clean and organised throughout the build. As shown in these images, they uphold their commitment to tidiness, which is always reassuring to see.
