Looped routes, clear thresholds, and choice
In therapeutic and inclusive landscape architecture—pioneered in institutions such as the Alnarp Rehabilitation Garden at the Swedish University of Agricultural Sciences (SLU) and Thrive’s Trunkwell Garden in Berkshire—paths are rarely laid out as dead-end corridors. Dead ends force a person to retrace their steps and can feel constricting when someone is anxious. Instead, a gentle figure-of-eight or primary loop with a shorter bypass lets a visitor choose a five-minute turn in the fresh air or a longer exploration.
Crucially, every seating bay should sit slightly off the main line of travel—recessed by at least 900 mm—so a person resting on a bench never feels as though others are walking directly across their toes, and so a wheelchair or rollator can pull alongside the bench on flush paving without blocking the path.
“When a path changes material at every junction—brick at the threshold, sawn stone along the sunny wall, timber at the shaded alcove—your feet know where you are before you even look up.”
— Wayfinding by Footfall, Puff Brain Picnc
Surface Study
Flush Joints & Tapping Edges
A 75 mm upstand brick or stone edging rail along one side of a path provides a continuous tapping guide for long canes and prevents wheels slipping into soft soil.
Refuge Bay
Recessed Seating Alcoves
Extending the paving slab 1,000 mm beside a timber bench with armrests creates a welcoming side-transfer or companion space.
Choosing low-glare, wheel-friendly path materials
Loose pea shingle is one of the most common mistakes in domestic sensory gardens: while it crunches pleasantly, stones deeper than 10 mm bog down narrow caster wheels, catch walking sticks, and scatter onto lawns. Compare the alternatives below for tactile richness and accessibility.
| Path Material | Underfoot & Acoustic Feel | Wheelchair & Cane Suitability | Glare & Maintenance Notes |
|---|---|---|---|
| Honed Buff/Grey Yorkstone Flags | Solid, silent, cool and matte | Excellent (Flush 4 mm mortar joints) | Low solar glare; brush occasionally in shaded damp spots. |
| Self-Binding Crushed Aggregate (Breedon) | Firm with a subtle dry grit crunch | Very Good (When rolled over type-1 sub-base) | Warm ochre tone; avoid on slopes steeper than 1:20. |
| Clay Pavers Laid Herringbone | Warm, slightly textured micro-chamfers | Excellent | Rich terracotta provides high visual contrast against dark soil. |
| Grooved Kiln-Dried Oak or Larch Decking | Slight warm hollow resonance | Good (Lay boards perpendicular to travel) | Include non-slip resin grit strips in shaded woodland zones. |
| Loose 20 mm Pea Shingle | Loud crunch, shifting instability | Poor (Sinks wheels and trips feet) | Reserve only for non-trafficked mulched margins around boulders. |
Designing the low-stimulation decompression corner
At Alnarp Rehabilitation Garden in Sweden, researchers documented that visitors experiencing high stress or sensory exhaustion initially avoid open, brightly coloured floral parterres. They gravitate first toward sheltered, enclosed green spaces where demands are minimal and no social interaction is forced.
Even in a modest back garden of 60 square metres, you can reserve a 2.5 m × 2.5 m corner for low-stimulation recovery:
Evergreen Backing at 1.6 Metres
Position the bench against a solid boundary wall clothed in self-clinging Hydrangea anomala subsp. petiolaris or a clipped yew screen so nobody can approach from behind.
Restful Foliage Without High-Contrast Spots
Surround the nook with Dryopteris erythrosora (autumn fern), Hakonechloa macra (Japanese forest grass), and Asarum europaeum (wild ginger) for soft sheen without jarring scarlet or neon blooms.
Bench Ergonomics
Choose untreated seasoned oak or cedar with a seat height of 450–480 mm, a supportive 100-degree backrest angle, and sturdy armrests on both sides to assist standing.
