Perched atop a rocky seaside promontory, this loft renovation is an efficient response to the problem of limited space with simplicity and restraint being the guiding principles of the design solution. The clients requested a design which would accommodate office work by day and intimate social and familial gatherings by night. The interior spaces have been completely reconfigured into an open plan evolving around a double height entry volume containing the principal stairway. Sliding partitions and fabric behind frameless glass have replaced traditional means of enclosure and spatial transition. A sculptural interplay of material, light and form defines spaces, which are intimate and communal, sheltering yet expansive. Indoor and outdoor living is integrated by frameless, bi-folding doors. Windows are positioned to embrace the view of the harbor, while second skin systems such as wood shutters mediate the late afternoon sun and provide privacy. The changing play of light on surfaces, the breezes that move through and around, the touch and smell of walls and gardens, the play of colors, the sound of spaces all play a part in the reception of architecture as it is lived in, and are important determinants in our well being.
