Working in Dunoon
We cover Dunoon and the postcode districts PA23. Island and remote projects are planned individually, with travel, deliveries and accommodation for the team agreed before the survey.
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.
Will the council need to approve it?
In Scotland a small porch can be permitted development (Class 1C) within limits on floor area, height and distance from a road; larger porches need planning permission, and building standards still apply, so we check whether a building warrant is needed.
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.
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.

Our process, step by step
Visits to Dunoon are arranged around travel; we confirm any travel costs in writing before the survey.
Site visit by arrangement
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
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
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.

On site, typically 2 to 4 weeks once approvals are in place. Before that, allow 2–8 weeks design and approvals.

Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.

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.
