Sandstone patio and planting – Sheen
Failing concrete patio replaced with mint fossil Indian sandstone, set on a proper MOT Type 1 base with a linear drainage channel against the house wall.
Initial conditions
The starting point in this East Sheen garden was a failing concrete patio that had simply reached the end of its useful life. Cracks had widened, levels had dropped and water routinely pooled against the rear wall of the house after rain. The surface was stained beyond recovery and had become a genuine trip hazard. Beyond the practical issues, the patio felt completely disconnected from the recently refurbished Edwardian property, visually dragging the garden backwards while the house had moved on.
Client brief
The clients wanted a natural stone patio that would sit comfortably with the age of the house rather than fight it. Longevity mattered more than speed, and they were clear that drainage needed to be corrected properly rather than disguised. The space needed to support outdoor dining for extended family while leaving enough garden beyond for lawn and planting.
Description of works
Design approach
Material choice did most of the heavy lifting here. Mint fossil Indian sandstone was selected for its warm, honeyed tones and natural variation, which soften with age rather than deteriorate. The patio was proportioned to suit the garden rather than dominate it, with bullnose edging creating a refined transition into the lawn areas. A discreet linear drainage channel was incorporated along the house wall so that water would be intercepted before it could cause future issues. Beyond the patio, the surrounding planting was refreshed to sit comfortably with the new stone and the Edwardian house behind it.
Construction details
The original concrete slab was mechanically broken out and excavated to allow proper sub-base construction. A fully compacted MOT Type 1 foundation was installed in layers to prevent settlement on the underlying clay, followed by a sharp sand screed to establish accurate falls. Calibrated sandstone slabs were laid with consistent joints and mortar pointing, while the drainage channel was connected into the existing system to ensure reliable runoff management even during heavy rainfall.
Results
The completed patio feels settled and appropriate to the Edwardian architecture rather than newly imposed. The stone warms visually in sunlight and provides a stable, level entertaining surface that the previous concrete never achieved. Drainage issues have been eliminated and the garden now flows naturally from the house rather than stopping abruptly at the threshold. It is used regularly for dining and gatherings, and the material will continue to improve in appearance as it weathers rather than degrade.
