Planning permission


Building regulations can be confused with planning permission, but they are fundamentally two different elements of the government’s planning and building programme, covered by separate acts of parliament.
Planning Permission is formal authorisation from a local authority for the erection or modification of buildings or similar development. Building Regulations control the construction and health & safety standards of a project. The same Planning Permission rules apply for conservatories, orangeries and extensions.

For further information visit the Government’s Planning Portal.

Project Management


During construction, it is essential that the project is coordinated correctly, ensuring that the building conforms to regulations and is finished on time.
This process involves: establishing the projects targets and aims; coordinating with contractors and suppliers; benchmarking progress; administering the design, as planned, to a high standard; controlling costs and expenses and reviewing the finished project.
