L-Shaped Granny Annexe

L-Shaped Granny Annexe

First Published: 13 April 2019
Refreshed: 30 September 2024
Reading Time: 2 minutes

Booths Garden Studios offers two options for creating a granny annexe in your garden. They have their flagship QC6 range, which is fully compliant with building regulations and planning-friendly, and their QCB range, built under the Caravan Act, which means it can often be installed without the need for a formal planning application.

You might wonder what 'QC' stands for. It refers to the 25-year maintenance-free lifespan guaranteed for these buildings.

The Largest Granny Annexe That Can Be Built Under the Caravan Act

A popular addition to the QCB range is this L-shaped building. It’s the largest granny annexe that Booths Garden Studios can install under the Caravan Act.

The L-shaped structure is made up of two sections: one measuring 24ft x 12ft (7.31m x 3.65m) and the other 12ft x 8ft (3.65m x 2.43m). These are joined to create a spacious open-plan living area, with a double bedroom leading off the main space.

A Light-Filled Home

Booths Garden Studios are well-known for their walls of glazing, which flood their buildings with natural light. This L-shaped QCB annexe is no exception. The walls where the two wings meet are fitted with floor-to-ceiling glazing, consisting of a mix of doors and windows.

As seen in these photos, the extensive glazing creates a bright, airy room. Privacy and light levels can easily be controlled with Venetian blinds.

Complete with Kitchen

The QCB granny annexe comes with a sleek, modern kitchen. Glossy white units and a grey worktop are neatly tucked into an alcove between the bedroom and the shower room. This clever design ensures that the kitchen doesn’t dominate the main living space.

All Modern Conveniences Included

The QCB garden annexe is also equipped with a shower room, featuring a generously sized shower. The room is finished with shower boarding, a practical, low-maintenance solution with minimal joints.

The shower room is completed with a basin and toilet, both of ample size.

Cost-Effective Granny Annexe

Booths Garden Studios have designed the QCB garden annexe to be one of the most cost-effective options on the market. This L-shaped version is priced at approximately £70,000 plus groundworks (guide price as of September 2024).

The cost of connecting the annexe to the mains for water, sewerage, and electricity varies depending on the distance from the house and other site-specific factors, so this must be quoted on a case-by-case basis.
