Extensions in and around Paisley
We cover Paisley and the postcode districts G78, PA1, PA2, PA3, PA4, PA5. The same team covers Barrhead (3 miles), Renfrew (3 miles), Johnstone (3 miles), Erskine (5 miles), all within easy reach.
For homes towards Dunbartonshire, Clydebank is around 5 miles away. Scotland's housing includes sandstone villas, terraces and tenements in the cities and plenty of post-war and modern houses and bungalows elsewhere. A building warrant is needed before work starts.
Planning and approvals in Paisley
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. Separately, almost every extension needs a building warrant from the council before work starts.
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.
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.
Included in a typical project
- Roof designs that tie into the existing hipped or gable roof
- Single-storey extension options assessed first
- Level thresholds and accessible layouts
- Planning application where needed
- Structural survey before any upward extension
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.
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Your questions about a bungalow extension in Paisley
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Paisley, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Paisley 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 you cover all of Paisley?
Yes. We cover Paisley and the surrounding parts of Renfrewshire and Inverclyde. Site visits are free and there is no obligation.
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.
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.
