Frequently asked questions
What drawings do I need for an extension
Most projects start with existing and proposed plans and elevations. We confirm the right set once we review your address and scope.
How fast can you survey
In most cases we can arrange the initial measured survey within forty eight hours of instruction.
Do you help with planning submissions
Yes. We can prepare drawings and support the submission route, including responding to questions during review.
Can you coordinate structural design
Yes. We coordinate with structural engineers so beams and load paths are designed and shown clearly on the drawings.
