Another coastal project - this time with SVARRE windows.

SVARRE is the ultimate window and door system with a unique design. The external toughened glass is part of a triple glazed unit that protects the timber frame and sash.

The external face of the SVARRE window is all glass, covering the well engineered timber work and presenting a seamless flat, shiny surface.

As an architectural element it is simple and stylish, working well individually or as linked units and in direct contrast to finishes like stone, timber, brick and plaster.
