What works best for Greenock houses?
Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
The types we would usually look at first for a home in Greenock are bungalow extensions, orangery extensions and single-storey rear extensions, depending on the garden and how the house is laid out.
Planning and building control 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.
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 about extensions in Greenock
How much does an extension cost in Greenock?
Using our Scotland factor (×0.98), a standard-spec single-storey extension of 20 m² is a guide £40,000 to £51,000 including VAT, and a 32 m² two-storey extension £56,000 to £74,000. Your written price follows the survey.

Yes, including the surrounding parts of Renfrewshire and Inverclyde. Site visits are free and there is no obligation.
