On gated land bordering the former Metropolitan Water Board HQ, the architecture is "modern Georgian" and slots confidently into this prized conservation area. New River is an artificial channel cut originally from springs in Hertfordshire to New River Head at Rosebery Avenue in Clerkenwell. It remains an essential part of the capital's water supply. Later, an estate of wide streets and garden squares was built, evolving into a village-like neighbourhood.
A listed boundary wall encloses the River Street site at the rear, and the new homes have light, open-plan interiors, above, plus plenty of connected outside space.
Completion is due in November. Prices from £1.85 million. Call Thomson Currie (020 7226 0000).
