L-shaped and corner garden rooms

Why an L-shape or corner room

• Two rooms in one: an office and a gym, a studio and storage, or a den and a bar.
• Uses dead corners at the end of the garden.
• Glazing on two sides for more light and a view back to the house.
• Keeps the lawn in one piece, rather than cutting the garden in half.

Planning

The shape makes no difference. All garden buildings count towards one 30 m² total, and you must keep 25 m² of garden. Both wings count. See the planning rules.

Cost and build

An L-shape has more wall, an extra corner and a more complex roof junction than a rectangle of the same floor area. Fewer suppliers offer it as a standard design, so it's often a bespoke build. Price both: two separate rectangular rooms can sometimes cost less, though they share the same 30 m² limit.

Design tips

• Put the doors on the garden-facing sides so both wings get light.
• Use the inner corner for storage, a WC or a kitchenette.
• Heat the two zones separately if you'll use them at different times.
• Keep the roof simple: a single flat roof over both wings avoids awkward valleys.
