Towns in Edinburgh and the Lothians
Working in Edinburgh and the Lothians
Towns we cover in Edinburgh and the Lothians include Edinburgh, Livingston, Musselburgh, Bathgate, Bonnyrigg, Penicuik, Broxburn. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Will the council need to approve it?
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 Edinburgh and the Lothians address depends on its history and any designations, which is why we check it at the first visit.
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.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.
What is included
- Two or three layout options to compare
- Structural calculations from an engineer (full pack)
- Planning drawings: existing and proposed plans and elevations, site and location plans
- Measured survey of the house and garden
- 3D views to check the look and the light (full pack)
- Building regulations drawings and specification
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.

Common questions in Edinburgh and the Lothians
Do you cover all of Edinburgh and the Lothians?
Yes, across the whole of Edinburgh and the Lothians. Site visits are free and there is no obligation.
Do I need building regulations approval in Edinburgh and the Lothians?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Who do I contract with in Edinburgh and the Lothians?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
