Homes in the Lothians
Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.
What goes into an upward extension?
An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.
- Structural survey of walls and foundations
- Roof removal and temporary weather protection
- Full fit-out of the new rooms

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.
Adding a storey in Scotland needs planning permission and a building warrant.
