Accessible Garden Care Outbuilding in Barnet | Lawfulness Confirmed
WEDRAWPLANS designed a purposeful, single-storey rear garden care outbuilding with wheelchair-accessible circulation and a wet room, and secured a Certificate of Lawfulness from Barnet Council on 30 March 2026. The scheme demonstrates how careful architectural drawings can establish the appropriate Class E planning route for a building that remains ancillary to the main home.

The challenge and solution
Accessible everyday support, with a sensitive garden footprint
The brief called for a dedicated support space ancillary to the main residence, incorporating a treatment area, wheelchair circulation and an accessible wet room. Rather than introducing an independent home, WEDRAWPLANS developed an integrated garden-building solution that remains connected to the residential use of the house.
The drawings demonstrated the building's single-storey form, flat roof, modest 2.5-metre height, garden siting, boundary relationship and the proposed internal arrangement. Barnet Council considered the specific use, dimensions and garden coverage before issuing a Certificate of Lawfulness under section 192.
This certificate confirms the lawfulness of the described proposal on the evidence and circumstances submitted. It is not a general approval for self-contained accommodation or a substitute for Building Regulations requirements.

Planning outcome & drawing work
Barnet Council issued a Certificate of Lawful Use or Development (Proposed), reference 26/0062/192, on 30 March 2026 for the erection of a rear outbuilding. The decision references PP01-R Plans, PP02-R Elevations, PP03-R 3D schematic view and P01 location and block plans. The council considered the proposed 2.5-metre flat-roof height, boundary relationship, garden coverage and its specific incidental ancillary care use under Schedule 2 Part 1 Class E. The certificate relates to the proposed development and the information submitted; it is not full planning permission for an independent dwelling or approval under the Building Regulations.
Approved documents referenced by the council
PP01-R proposed garden care layout; PP02-R proposed elevations; PP03-R schematic architectural views; and P01 location and block plans, as identified in the council's decision notice.

How WEDRAWPLANS supported this approval
WEDRAWPLANS developed the single-storey outbuilding concept and prepared the proposed internal plan, elevations, schematic architectural views and planning notes for a proposed Section 192 Certificate of Lawfulness. The drawing package demonstrated the intended ancillary use, accessible layout, building height, garden setting, boundary relationship and site coverage so Barnet could determine the appropriate Class E planning position.

- The certificate concerns an outbuilding ancillary and incidental to the main dwelling, not a separate residential unit.
- The proposed single-storey flat-roof structure is shown at 2.5 metres maximum height where close to a garden boundary.
- Barnet considered the location within the residential garden and the curtilage coverage against Class E permitted-development rules.
- A materially different proposal, use or change in relevant circumstances needs separate consideration; Building Regulations compliance is not established by the certificate.
