Sea Roads is a detached house in Penarth in the Vale of Glamorgan noted for its distinctive Modernist design.
It was designed by the Welsh architect Gordon Griffiths for John Gibbs and built in 1939.
[1] It is a rare example of Modernist domestic architecture of the 1930s in Wales; featuring typical Modernist details of white walls, flat roofs and a curved internal staircase framed by a full height window.
All of the main rooms of the house and four of the bedrooms overlook the garden.
[1] The Cadw listing describes Sea Roads as an "exceptionally well-preserved modernist house" and notes its "expressive use" of windows to demonstrate the curvature of the facades and the internal organisation of the interior.
