Patio Design Guide: Layouts, Patterns and Planning
How to Design a Patio
A well-designed patio extends your living space outdoors. Before picking materials, plan the size, shape, drainage, and layout pattern. This guide walks you through the key design decisions and provides reference tables to help you plan with confidence.
Patio Size Guide
| Use | Minimum Size | Comfortable Size | Generous Size |
|---|---|---|---|
| Bistro table for 2 | 2m x 2m (4 sqm) | 3m x 3m (9 sqm) | 3.5m x 3.5m (12 sqm) |
| Dining table for 4-6 | 3m x 3m (9 sqm) | 4m x 4m (16 sqm) | 4.5m x 4.5m (20 sqm) |
| Dining + lounge area | 4m x 5m (20 sqm) | 5m x 6m (30 sqm) | 6m x 7m (42 sqm) |
| Full outdoor kitchen | 5m x 6m (30 sqm) | 6m x 8m (48 sqm) | 7m x 9m (63 sqm) |
| Hot tub base only | 2.5m x 2.5m (6 sqm) | 3m x 3m (9 sqm) | 4m x 4m (16 sqm) |
A common mistake is building too small. Allow 1m clearance around furniture for comfortable movement. Use our paving calculator to price up different sizes and see how material costs scale.
Laying Patterns
| Pattern | Difficulty | Waste | Best For | Visual Style |
|---|---|---|---|---|
| Stack bond (grid) | Easy | 2-3% | Modern patios, small areas | Clean, contemporary |
| Stretcher bond (offset) | Easy | 5% | Paths, patios, walls | Classic, versatile |
| Herringbone (45 or 90 degree) | Moderate | 8-12% | Driveways, high-traffic areas | Traditional, strong |
| Basket weave | Moderate | 5-8% | Period properties, garden paths | Decorative, charming |
| Random ashlar (mixed sizes) | Hard | 3-5% | Natural stone patios | Organic, premium |
| Circular/fan | Hard | 15-20% | Feature areas, focal points | Dramatic, eye-catching |
Herringbone is the strongest pattern for driveways because the interlocking angles resist the lateral forces from turning wheels. For patios, choose the pattern you like best — structural strength matters less on foot-traffic surfaces.
Drainage Planning
| Scenario | Solution | Cost | Gradient |
|---|---|---|---|
| Patio slopes away from house | Natural fall, no extra drainage | EUR 0 | 1:60 to 1:80 |
| Enclosed by walls on 3 sides | Linear drain along lowest edge | EUR 150-400 | Toward drain |
| Large patio (30+ sqm) | Aco drain + soakaway | EUR 300-800 | Toward drain |
| Patio against house wall | Lower patio 150mm below DPC | EUR 0 | Away from house |
| Sloped garden | Retaining wall + stepped levels | EUR 500-2000 | Each level drains separately |
The golden rule: water must always flow away from the house. A fall of 1:60 means the surface drops 17mm for every metre of distance from the house. Use a long spirit level and shims to check the gradient as you lay each row.
Material Comparison for Patios
| Feature | Concrete Pavers | Natural Stone | Porcelain | Composite Decking |
|---|---|---|---|---|
| Cost per sqm | EUR 20-35 | EUR 30-80 | EUR 40-90 | EUR 35-70 |
| Lifespan | 20-30 years | 30-50+ years | 25-40 years | 15-25 years |
| Maintenance | Low | Medium (seal every 3-5 years) | Very low | Low (annual clean) |
| Slip resistance (wet) | Good | Variable | Excellent | Good |
| Heat retention | High | Moderate | Low | Moderate |
| DIY difficulty | Easy | Moderate | Moderate | Easy |
| Look and feel | Uniform, modern | Natural, unique | Sleek, modern | Warm, natural wood |
For a direct comparison with timber, see our composite vs wood decking guide. Paving is better for dining areas (stable furniture legs) while decking is better for lounging areas (warmer underfoot in spring and autumn).
Planning Checklist
Before ordering materials, work through this checklist:
- Measure the area — Use our paving calculator for exact quantities
- Check the DPC level — The finished patio must sit 150mm below the damp proof course
- Plan drainage direction — Mark the fall with string lines before excavating
- Choose the pattern — Herringbone for driveways, stretcher bond for patios
- Check for underground services — Use a CAT scanner or contact utility companies before digging
- Order materials with 5-10% extra — For cuts, breakages, and pattern matching
- Allow access for delivery — Bulk bags need a truck with a grab or crane arm
Patio vs Decking
| Factor | Paving | Decking |
|---|---|---|
| Cost (DIY, 20 sqm) | EUR 600-1400 | EUR 500-1200 |
| Installation time | 3-5 days | 2-3 days |
| Requires excavation | Yes (150-250mm) | No (surface-mounted or on joists) |
| Furniture stability | Excellent | Good (level) |
| Underfoot comfort | Hard | Softer, warmer |
| Drainage | Requires grading | Built-in gaps between boards |
| Lifespan | 25-50 years | 15-25 years |
Many homeowners combine both — a paved dining area next to the house and a raised deck further into the garden. This creates distinct zones and adds visual interest. Check our decking calculator and paving cost calculator to compare material costs for your exact dimensions.
These calculations are estimates only. Actual requirements may vary depending on surface conditions, product specifications, and installation methods. Always consult a qualified professional for precise measurements.
