Structural suitability

A barn conversion is a wonderful opportunity to give an unused building a new lease of life as a home.

From the start of the process, we will work with you to design the home of your dreams whilst ensuring your barn meets the criteria for planning approval – read more about Class Q barn conversions.

As part of our service, we will assess the structural condition of your barn. If your barn is structurally suitable for conversion under Class Q, we will provide a summary report aimed at supporting the project.

Building control application

Once you have been granted full or Class Q permission, your barn conversion will need to meet building regulations.

Our team will have construction details and technical drawings for your barn conversion ready within 2 to 3 weeks.

As with planning applications, we will prepare and submit your building control application and deal with the council on your behalf.

If structural designs (also known as structural calculations) are required, we can also prepare these and submit them as part of the building control application. Read more about building control & construction specification packages.
