Who a utility room extension suits
- Houses with a side passage or small rear corner
- Kitchens that have run out of space for appliances
- Busy family homes
A good utility works like a back-of-house corridor: in from the garden, boots off, coats on hooks, washing on the way through. We plan the door positions so it doesn't become another room to walk around.
Planning rules that apply in Greenock
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.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
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.

Questions people ask about utility room extensions
Will my neighbours in Greenock 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.
How long does a utility room extension take to build in Greenock?
On site, typically 6 to 10 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.
Do I need building regulations approval in Greenock?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
How much does a utility room extension cost?
Our guide range is about £1,860 to £3,430 per m² including VAT, with a minimum of around £14,000. An 8 m² standard-spec utility is typically £17,500 to £22,000 in Greenock.
Can a utility have a toilet?
Yes, space permitting. A WC needs drainage and extraction, which we plan into the design.
