Who a bungalow extension suits
- Families wanting more space on one floor
- Bungalows on larger plots
- Homeowners planning for later life
Bungalow roofs are often hipped, which makes tying in an extension roof a careful job. We draw the roof junction early because it drives both the look and the cost.
Planning and approvals 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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
Local to Greenock
We cover Greenock and the postcode districts PA15, PA16, PA19. The same team covers Erskine (12 miles), Johnstone (13 miles), Paisley (15 miles), Renfrew (15 miles), all within easy reach.

How the project works

Free site visit
It starts with a visit to your house to measure, check access and talk through ideas and budget.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Common questions in Greenock
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Greenock, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Greenock?
Yes. We cover Greenock and the surrounding parts of Renfrewshire and Inverclyde. Site visits are free and there is no obligation.
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.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,720 to £3,330 per m² including VAT. Going upwards is priced after a structural survey.
