An office building is a commercial property used primarily for desk-based work, ranging from small converted shops to large multi-storey blocks. Across Greater London, large office stock is concentrated in the City fringe (Islington, Hackney), Westminster, Camden and emerging clusters in King's Cross and Old Street. Drainage characteristics typically include WCs and basin facilities on each floor connected to a shared internal soil stack, plus kitchenettes and tea points on smaller waste branches. Common issues include blockages from inappropriate items flushed by occupants, leaks at branch connections in suspended ceilings and persistent odours from poorly trapped fittings. Multi-tenanted buildings can suffer from disputes over responsibility. Facilities managers should arrange annual stack maintenance and clear written procedures for tenants to report drainage problems before they escalate.
