Clapton Library is a Grade II listed Edwardian neo-classical Library which has been restored to its former glory, retaining and uncovering many of its original features, while updating its facilities with a striking new extension. Sustainability has been at the heart of the refurbishment, with energy efficient green technologies being utilised throughout the project. These include rain water harvesting; solar water heating and energy efficient lighting and heating systems. The existing windows have been upgraded in an unobtrusive manner using hinged casements linked to Series 30 Lift-Out panels to match the window sight lines. Since this project was completed the Series 30 has been superceeded by the Series 31 lift-out.
