Project case study

House Extension and Renovation

This extension to, and renovation of a historic property in Ramsbottom was a particularly rewarding challenge. We undertook a thorough investigation and developed a deep understanding of the existing fabric. We specialise in house extensions and renovations of this nature. It is important to preserve the existing character of an historic property by integrating modern construction materials in a sensitive and considered manner. This project investigated the relationship between the existing historic fabric and contemporary architectural ideas. Our client was passionate about their existing property and we enjoyed using our expertise to develop designs for their house extension and renovation.

House extension

The ‘infill’ extension is positioned between two existing structures, the historic house and detached double garage. Planning constraints were addressed by integrating full height glazing and a roof profile which did not dominate the existing character of the surrounding architecture. The architectural language is bold and modern, juxtaposed against a historic back drop of rich, dark stone. We wanted the house extension to adopt the solidity and strength of the existing stonework and echo the sturdiness of the existing property. We selected timber cladding by Russwood, a company based in Scotland. The species is Siberian Larch which is a hardwood treated with SiOO:X, a surface coating impregnation system which creates a consistently weathered appearance.

The existing property was too dark becuase natural light struggled to penetrate through small, narrow windows. The glazing strategy in the new house extension spreads light generously throughout the space. Triple glazed aluminium casement windows and a sliding door keep the space warm and cosy by limiting heat loss. The concrete slab was cast with underfloor heating pipework, which serves to maintain a warm and comfortable ambient environment. A concealed entrance was created within the kitchen design between the garage and kitchento access a small pantry.

House renovation

The existing house was re-configured and adapted to create a better relationship with the new house extension. An opening in the existing external wall created the primary connection with a new entrance formed via the existing kitchen. A new library and snug were created from converted ancillary spaces. New flooring and lighting helped to sensitively modernise existing spaces, while retaining their character. Existing layers of plaster were removed to expose the original stonework which allowed the external walls to breathe and shed excess moisture. Returning the property back to its natural state was fundamental to leverage improvements to the energy efficiency of the extended portion of the house.

Together, the house renovation and extension combine to create a hierarchy of spaces intended for living and entertaining. Both enhance the position of the property by creating views across a lush and rolling, native Lancastrian landscape.
