modular glass extensions

ODC offers modular glass extension designs. Structural glass walls, glass roof panels or rooflights are combined with floor to ceiling glass sliding doors or bifolds to create bright, light new spaces with instant access to the outdoors.

Side infill extensions or side return extensions, as they are also called, are a popular option with homeowners, making great use of a passageway or storage area to extend a kitchen or open up family spaces.

From double storey designs with up and over glazing to a three-sided glass box with a solid roof – our extensive range of products have the technical specifications to deliver the look and functionality you want.

GLASS ROOFS and GLASS Curtain WALLS explained

Our modular fixed glass units can form minimalist glass façades and glass roofs to suit any extension design.

Large areas of glass can be created with custom-made panels or by connecting multiple panels using structural silicone. Depending on its dimensions, glass beams or steel sections will give your glass walls and roof the structural support they require.

Double height and single storey extensions featuring beautiful expanses of clear glass and incorporating any of ODC’s extensive range of bifold and sliding doors are possible.

An extension with a ‘Grand Design’ wow factor is an option for any home. Visit this ODC project, a double storey glass extension, featuring a glass roof and a pair of custom-made front doors.
