You should unclip hanging baskets, shift recycling boxes and warn neighbours about skips.

Ground conditions dictate footing depth. A property resting on soft clay needs far deeper concrete trenches than one on chalk. Hidden drains, old tree roots, and moving a single soil stack can alter raw material spending before any brickwork rises above the damp-proof course.
Gather any old property deeds showing your true boundary lines. Sketch how you actually move through your ground floor, note where your electric fuse board sits, and clear access to garden manhole covers so we can see the drainage direction right away.
Digging foundations near a shared boundary wall in Chatham usually means serving formal boundary notices. You must agree on structural access, protective hoarding, and working hours with adjoining owners before machinery starts breaking surface turf.
Pitch determines your choice. Shallow slopes require seamless rubber membranes or standing-seam zinc to stop driven rainwater penetrating laps, whereas steeper roofs take matching clay tiles that blend directly into the main house.
