Layout
Test the usable area, not just the square metres
Place or measure the table, chairs, barbecue and planters you expect to use, then allow space to pull out chairs and walk through. A large paved area can still feel awkward if door swings, steps and routes through the garden are ignored.
Consider sun, shade, privacy and views at the times the patio will be used. The most obvious position beside the house is not automatically the most comfortable one.
- Furniture dimensions and circulation
- Doors, steps and principal garden routes
- Sun, shade and overlooking
- Connection to lawns and planting
Levels
Resolve thresholds and falls before fixing the pattern
The finished patio has to meet existing doors, air bricks, drains and garden levels safely. Ask the contractor to explain proposed falls and where surface water will go.
Where a patio has failed, show settlement, cracked joints, loose edges and persistent wet areas. The new specification should address the cause rather than conceal it.
- Door and damp-sensitive levels
- Drain and inspection-cover positions
- Direction of proposed falls
- Steps, retaining edges or ramps
Finish
Choose a material as part of an installation system
Porcelain, sandstone and concrete paving each require compatible preparation, bedding, cutting and jointing. Product data, slip characteristics and installation instructions should inform the proposal.
Ask to see a representative sample and discuss colour variation, staining, cleaning, sealing where applicable and future replacements. Be cautious of a comparison based only on supply price per square metre.
Quote comparison
Make the hidden work visible
A comparable quote states demolition, excavation, disposal, sub-base, bedding, paving, cuts, edges, jointing, drainage and making good. It should also explain assumptions about access and ground conditions.
If landscaping around the patio will follow later, plan service ducts, planting beds, levels and routes now. That reduces the risk of lifting finished work.
- Measured area and material allowance
- Ground preparation and waste
- Drainage and edge details
- Start conditions, programme and exclusions
