Planning rules that apply in Cumbernauld
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.
The planning position for a specific Cumbernauld 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.
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.
Applications are decided by your council as planning authority.
Who an orangery extension suits
- Period and detached houses with a garden view
- Homeowners replacing an older conservatory
- Those who want daylight without overheating
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.

Common questions in Cumbernauld
Will my neighbours in Cumbernauld 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.
Do I need building regulations approval in Cumbernauld?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Do you cover all of Cumbernauld?
Yes. We cover Cumbernauld and the surrounding parts of Lanarkshire. Site visits are free and there is no obligation.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.
