Working in Dunoon
Postcode districts we cover around Dunoon include 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.
Do I need planning permission in Dunoon?
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.
The planning position for a specific Dunoon address depends on its history and any designations, which is why we check it at the first visit.
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
- Completion certificate on sign-off
- Structural calculations for beams, lintels and foundations
- Building regulations drawings and written specification
- Inspection bookings throughout the build
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.
