Useful information

Surveys and access - chimney drawings

Preparation identifies missing information about materials, access, working space and separation between occupants and the work area.

These are principle drawings, not drawings of your property. Dimensions, support arrangements and execution details require a site assessment and, where needed, a structural design.

Material survey around the flue

Survey markers identify locations where material information may be needed: flue lining, board, seal and surrounding construction. Colour does not indicate the presence of asbestos.

Access and work area

The plan separates the house, access, potential logistics space and an occupant route. It is a discussion drawing; scaffolding, lifting equipment and barriers require a site-specific plan.

From a principle to a drawing for your home

Include the address, existing plans, photographs, the parts to remain and your preferred finish with your enquiry. A designer or structural engineer establishes which measurements, investigations and documents are needed.
