Residential Terrace

Executive Summary
This project focused on the complex structural leveling and high-end resurfacing of a rear residential terrace. The primary challenge involved correcting significant topographical irregularities and outdated drainage systems to create a perfectly flush, precision-engineered outdoor living space that aligns seamlessly with the property’s modern bi-fold threshold.

Project Type Hardscape Engineering & Grade Leveling

Surface Area ~65 Square Meters

Material Specification Natural Indian Sandstone (Multi-tonal Riven Finish)

Sub-Base Construction Type 1 MOT compacted base with full mortar bed

Project Duration 3 Weeks

Budgetary Scope £12,000 – £18,000

Technical Analysis & Execution

• •Topographical Correction: The project required a comprehensive "level and rebuild" strategy. This involved the excavation of the original failing substrate and the implementation of a new, laser-leveled sub-base to ensure a uniform gradient across the entire footprint.
• •Precision Drainage Integration: To mitigate water ingress and surface pooling, a discreet linear drainage system (Aco drain) was integrated directly against the building's facade. The terrace was engineered with a subtle 1:60 fall, directing runoff away from the primary structure toward the peripheral soft landscaping.
• •Material Selection & Aesthetics: We utilized premium-grade, hand-cut sandstone flags. The stone was laid in a random bond pattern to emphasize natural tonal variations, ranging from deep ochre to cool grey. The joints were finished with a high-performance, weather-resistant polymeric resin for longevity and weed suppression.
• •Structural Retention: The perimeter features a bespoke timber sleeper retaining wall, designed to manage the elevation change between the new terrace and the neighboring property line, providing both structural stability and a clean visual border.

The completed works have transformed a previously uneven and underutilized area into a high-performance transition zone. By successfully reconciling the internal floor heights with the external paving, the project has significantly enhanced the property's flow, providing a durable, low-maintenance platform for high-end outdoor entertaining.
