Is a side return extension right for your house?
- Narrow galley kitchens
- Homes where the garden is too small to lose much depth
- Victorian and Edwardian terraces with a rear outrigger
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.
Local to Penicuik
Postcode districts we cover around Penicuik include EH26. The same team covers Bonnyrigg (6 miles), Edinburgh (8 miles), Musselburgh (10 miles), Broxburn (12 miles), all within easy reach.
Just over the Scottish Borders border, Peebles is about 12 miles away. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Do I need planning permission in Penicuik?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
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.

Side return extension questions answered
Will my neighbours in Penicuik be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Who do I contract with for a side return extension in Penicuik?
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 building regulations approval in Penicuik?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
How much does a side return extension cost?
Our guide range is about £2,060 to £3,720 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £25,500 to £32,500 at standard spec in Penicuik, more in London.
