LABC Local Council Planning Information

From Spring 2020, Local Authorities in the SouthEast will be issuing a free Converting Your Property booklet to guide local residents and business owners through the design and planning process for property conversion and ‘change of use’ projects. This is part of a Government initiative to address the shortage of housing in much of the UK and the surplus of empty offices, shops and former industrial buildings.

The comprehensive guide will cover all aspects of your project design and viability with information about Planning, Building Control and Environmental Health, legislation, advice on converting different types of buildings, necessary consents and insurances, and guidance on Houses of Multiple Occupation (HMOs).

The guide will be automatically issued when you make an enquiry regarding property conversion and home improvements via your Local Authority Building Control (LABC) or Planning Departments.

As a trusted local service provider, you will find full details of our structural and civil engineering services in the property conversion guides for Brighton & Hove City Council and Adur & Worthing Councils.
