Syon & Brentford Lock sits on the Thames in the north of Hounslow, covering Syon Park and the canalside basins east of it. Roughly half the ward falls inside conservation area. The 59 listed buildings include Grade I Syon House — the Percy family's London seat since 1594, with interiors remodelled by Robert Adam from 1762 and grounds by Capability Brown — plus the Grade I Syon House Conservatory and Flora's Column. Syon Park itself delivers 75 hectares of green space, total green space reaches 88, and heritage, nature and culture scores are all strong. Public-transport access is moderate with Syon Lane and Brentford on South Western Railway. The trade-offs: safety scores trail the borough median, only five outstanding-rated schools are within reach, and air quality reflects the proximity of the M4 and the A4.
