Photograph the proposed area from the house and from the garden. Mark roughly where you imagine the patio finishing, and think about furniture with room for people to move around it. Tell us whether you want an existing area renewed, extended or replaced with a different shape.
Include close pictures of damaged paving and places where water gathers. In a London terrace, access may run through the house or along a narrow passage, so show that route in full. Mention steps, shared entrances and restrictions on where materials can be handled. You do not need a finished design to start the enquiry.
