Floor planning a new build in Lewisham
Floor planning a new build in Lewisham means drawing every storey to scale, with room sizes and stairs dimensioned, so Lewisham Council can validate the application and check the layout. DrawingsDirect prepares these plans within new-build drawings from £1,450.

What a new-build floor plan has to show
A floor plan is a horizontal slice through the house, one per storey. It carries wall thicknesses, door and window openings, the stair, the kitchen and bathroom fittings and a dimension on every room. The council reads it to see whether the rooms are usable, and the building control surveyor later reads the same plan to check escape routes and stair geometry.
We draw the floor plans first and build the elevations and sections from them, so the three never disagree. If you only have a sketch on paper, we can start from that.
Measure the plan against the space standard
The nationally described space standard sets a minimum gross internal area for each size of home. A one-bedroom, one-person dwelling needs at least 39 m2, or 37 m2 with a shower room instead of a bathroom. A plan that falls under the figure for its bedroom count gives the case officer an easy reason to object.
Because the check is arithmetic, it belongs at the first sketch, not after the application is in.
The Planning Inspectorate decided 162 householder appeals against Lewisham between 2021 and 2026, and 30% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609).
How Lewisham Council has decided applications
Lewisham made 1,256 planning decisions of every kind in the four quarters from 2025 Q3 to 2026 Q2, and 196 were refusals (our analysis of MHCLG planning application statistics, table PS2). Among householder cases it decided 578, including prior approvals, and granted 89% of them.
Excluding prior approvals, 95% of its householder decisions came within 8 weeks, the statutory period for an application that is not major development under article 34 of the Development Management Procedure Order. Those figures are about householder and mixed cases. A new house is a larger decision, so they describe the council, not your result.
Appeals against Lewisham decisions
The Planning Inspectorate decided 162 householder appeals against Lewisham between 2021 and 2026, and 30% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609). Most refusals that went to appeal stood, which is a reason to get the floor plans right before applying instead of relying on a second chance.
Other Lewisham drawings we prepare
If your plans are for an existing home instead, see our Lewisham loft conversion drawings, our side return extension drawings or the floor plans service for Lewisham. Once planning is settled, the building regulations drawings for Lewisham turn the layout into a construction set.
