1 Watersplash Lane, Hayes

The Development

1 Watersplash Lane comprises a two-storey semi-detached C3 dwelling on a suburban corner plot in Hayes, London. The site occupies a prominent position at the bottom of a short cul-de-sac, immediately adjacent to the pedestrian entrance of Crane Park (public open space).

The proposal involved the conversion of the existing dwellinghouse and erection of a two storey building to accommodate 4 x 2-bedroom flats, including rear dormers and single storey rear extensions.

Site Context

The immediate context is characterised by early 20th century semi-detached houses of similar scale, with a consistent building line, front gardens converted to driveways, and pitched tile roofs. More recently, a multistorey residential housing scheme has been developed opposite the site replacing the previous Public House site.

The frontage and side boundary previously presented a visually poor street scene for users of the public realm, detracting from both the cul-de-sac and the park gateway. The development was designed to address this while maximising the site's potential.

Planning Strategy

Planning Pros prepared a comprehensive Planning Statement assessing the merits of the proposal against material considerations and relevant planning policies. Our strategy focused on demonstrating compliance with the NPPF (2024) and Hillingdon Local Plan policies.

• •Street Scene Improvement: Removal of block wall and redundant sheds/outbuildings to clear visual clutter and create an active side elevation.
• •Design Integration: Flush front alignment with the existing principal elevation to form a legible design appearing as an end of terrace dwelling.
• •Landscape-led Parking: Permeable block paving with soft landscaping and integrated discreet bin/cycle storage.
• •Amenity Justification: Proximity to Crane Park public open space as compensation for limited private amenity on upper floors.

Transport & Parking

A TRICS assessment was conducted demonstrating that the development would generate a negligible impact on the local highway network with only 6 daily vehicle movements. The proposal includes:

• •Car Parking: 3 off-street spaces, compliant with London Plan maximum standards for PTAL 2-3.
• •Cycle Parking: 9 secure cycle parking spaces, exceeding London Plan minimum requirements.
• •EV Charging: 1 active 7kW electrical charging point as per condition.

Result

Planning permission was granted on 17th April 2026 by London Borough of Hillingdon (Ref: 13077/APP/2025/1907). The decision confirmed that the proposal aligns with the NPPF and local policy by making efficient use of a suburban plot to provide much-needed housing.
