After searching for many years, we were able to purchase an old 'water works' pumping station. The original building has been converted into our storeroom. A new two-storey extension houses our administrative offices.
The brief we had for the new office was that it should work in harmony with the original structure but be constructed in alternative materials. We also had to look at the environmental impact of our business.
The extension is highly insulated, clad in oak boarding and is heated by a wood burning stove to enable us to burn all our waste wood rather than using oil or electric for heating. Although the initial build cost was higher, this will result in long-term savings on running costs.
