Planning rules that apply in Crieff
In Scotland the questions are whether the extension falls within householder permitted development (Classes 1A to 1D) or needs planning permission from the council, and the building warrant, which is required before construction begins and is followed by a completion certificate.
The planning position for a specific Crieff address depends on its history and any designations, which is why we check it at the first visit.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
Applications are decided by your council as planning authority.
What we take care of
- Planning drawings: existing and proposed plans and elevations, site and location plans
- Two or three layout options to compare
- Structural calculations from an engineer (full pack)
- Building regulations drawings and specification
- Measured survey of the house and garden
The most expensive changes are the ones made after the steel is ordered. A good design stage settles layout, heights, glazing and services on paper, so the build price is firm.

Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

We visit your Crieff home, measure up, talk through what you want and check the planning position.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
