St Helen's House is a previous inclusion on the English Heritage "Buildings at Risk" register. Grade I listed and occupying a prominent site in the centre of Derby, the building has been sensitively conserved and converted using best conservation practice. The practice worked closely alongside English Heritage and the Derby Council conservation team to find a sustainable long term use for the building which reopened as an office for a leading regional accountancy firm, and is now mixed offices for a structural engineer.
The practice was involved in assessing the condition, significance and related costs of repair to establish requirements for a funding package. This included designs for a sizeable enabling development on adjacent land. Works included conservation of the fine interiors including metalwork to stairs and highly decorative plaster ceilings to the principal rooms. Externally extensive repairs were undertaken to the stone facade, cornice and pediment whilst the building was completely re-roofed, overhauling internal rainwater pipes.
The building was built in the Palladian style around 1726 as a private residence. It later became Derby Grammar School until becoming council offices in 1972. The new office use sensitively reuses the buildings without extensive internal alteration or subdivision of primary rooms. The project was a recipient of a Georgian Group award as well as other regional civic awards.

The role of a building and site in supporting and enhancing ecosystems and native species.
The greenhouse gas emissions from the lifecycle of building materials, including extraction, manufacturing, transport, construction, maintenance, and disposal. The conservation team has an especially thorough understanding of how different building materials respond to climate and weather in the short and long term. This expertise helps us to avoid costly errors when specifying building materials.
The greenhouse gas emissions from energy consumption required to operate a building (e.g., heating, cooling, lighting, appliances). The engagement of Services and Energy consultants from the feasibility stage onwards helps our clients to explore lifetime energy consumption and improve efficiency.
The amount of water consumed during a building's operation and its broader impact on water resources.
The impact of building design and materials on occupants' physical and mental health. We guide clients through all their options when it comes to occupant well being and technology.
