Commercial to residential conversion
A vacant single-storey commercial building, redesigned as three two-bedroom houses within the existing footprint. We prepared the survey and design drawings and managed the application through to planning approval (a planning agent submitted it). Published with the owner's permission.
The brief
The owner bought a vacant single-storey commercial building and wanted to know the best use of the building and site, then needed drawings and planning permission to convert it into homes.
What we did
- A measured survey, with existing floor plans, elevations and a block plan
- The layout of three two-bedroom houses inside the existing footprint, each with its own entrance, parking and garden
- Proposed elevations, with new entrances and glazed doors out to the gardens
- A block plan showing access, parking, gardens and 1.8 m close-board fencing
- We managed the application through to approval; a planning agent submitted it
What made the numbers work
The value was in seeing that an existing single-storey building could become three homes without extending it, then setting out parking, gardens and access in a way the council would approve.
