In any house or outdoor space project, there is an area often dealt with last, almost reluctantly:the parking area.
And yet, it is an integral part of the welcome, the first impression, daily comfort — and has adirect impact on soil permeability, vegetation, and the overall aestheticsof the place.
Designing a parking area is not just about laying concrete. It isthinking about usage, flow, greenery, and light.And it is a unique opportunity tocreate a smooth transition between the roadway, architecture, and garden..
1. The parking area: a technical space, but not secondary.
What good design must anticipate:
- Theactual number of vehicles(residents + visitors)
- Theease of manoeuvring(without having to do 12 reverse maneuvers)
- Thevisibility at night(soft and targeted lighting)
- Thepedestrian pathwaythat is secure and pleasant.
- Thevisual impact from the house or the street.
- Thedialogue with the garden and the plantings.
💡 The parking area is a space of intensive use. It must therefore be designed with the same level of requirement as the terrace or the flower beds.
2. Types of surfaces: permeable vs non-permeable
Non-permeable surfaces (to be used with caution):
-
Smooth or deactivated concrete / sandstone paving...
➤ Durable and modern, but completely impermeable
➤ To be combined with drainage strips -
Asphalt / tarmac
➤ Durable but very 'urban', heats up in summer, not eco-friendly
➤ Rarely used in a private garden
Permeable surfaces (to be preferred):
-
Drainage paving(spaced + permeable joints)
➤ Aesthetic, technical, effective for slow drainage -
Vegetable-friendly cellular slabs (concrete or plastic)
➤ Attractive idea, but fragile if poorly laid
➤ ⚠️ Often break if wheels are turned while stationary, or if the sub-base is insufficient -
Stabilised gravel (honeycomb + geotextile)
➤ Very aesthetic, easy to lay, good drainage
➤ Regular maintenance: weeding and re-leveling -
Compacted stone
➤ Rustic solution, ideal for temporary car parks or integrated into nature
💡 Thinking 'permeability' means anticipating rainwater management, reducing heat effects, and preserving living soils.
3. Dimensions and ergonomics: how many m² per car?
Ideal area per parking space:
- Standard space: 2.5 m x 5 m = 12.5 m²
- Comfortable space: 3 m x 5.5 m = 16.5 m²
- Access and manoeuvring(turning area, setbacks): allow for an additional 30 to 40% of surface area
Rule of thumb:
For a smooth parking area for 2 cars + occasional guests:
👉 35 to 40 m²minimum (excluding pathways)
💡 It is better to allow a bit more well-vegetated space than a parking area that is too tight, poorly used, and a source of daily stress.
4. Integrate vegetation to lighten visually
A parking area does not have to be a grey blot in the garden.
Landscaping tips:
- Create planted stripsbetween spaces
- Hide carsbehind a low hedge or grasses
- Play with heights: a light tree (Gleditsia, Amelanchier, Betula) can structure the space
- Integrate ground-cover plantsin the cells
- Use planted retaining wallsif the land is sloped
💡 A green parking area is also an oasis of freshness and biodiversity!
5. Other elements not to be overlooked
- Lighting: recessed lights, solar beacons, indirect lighting → safety and atmosphere
- Noise: gravel can create a 'country entrance' atmosphere or be avoided depending on the desired style
- Slope: beware of slippery areas in winter
- Maintenance: ensure easy access for weeding, leaf blowing, and cleaning
- Edging: they must be clear, durable, and designed to prevent gravel dispersion
Conclusion
A good car park isinvisible without being non-existent, practical without being intrusive, and above allintegrated into an overall landscape logic.
It is a welcoming, transitional, fluid space — which can be beautiful, green, understated and intelligent.
