Grade I listed Tyntesfield is a Gothic Revival house with an estate, and was acquired by the National Trust in 2002. The house was designed by John Norton, a close friend of Augustus Pugin, and dates from 1863. Following the success of the project's Heritage Lottery Fund bid, we were appointed to provide building services consultancy and advise on sustainability as part of a £20m restoration project and a wider estate masterplan.
The original interiors have survived virtually intact and in the installation of new services, the work has been done sympathetically within the original building fabric, with discrete routing planned in advance of all works and minimal impact on existing finishes.
The electrical services for the whole house have been replaced, and environmental heating and monitoring for control of the relative humidity in the principal rooms introduced. Comfort heating has been provided for staff and volunteer areas and accommodation. The original installations have been retained for the historic record — those that are still relevant have been restored to working order, and more recent unsympathetic ones tidied up. Wherever possible, pipework, conduit, electrical back boxes and face plates, light fittings and radiators have been reused and refurbished.
Power was originally supplied by a generator located in the engine house, which is now the education centre. A replacement CHP installation was considered but thought unviable, and biomass boilers chosen instead. Separate biomass energy centres serve the house and Home Farm. Advice was sought from relevant specialists concerning the numerous local bat species in relation to the installation of the boilers, external lighting and other equipment.
At Home Farm, solar thermal water heating, photovoltaic panels, daylight-linked lighting controls have also been installed, and a building constructed using straw bales.
Reflecting the client's 'inclusion for all' approach in the masterplan, most works, such as the installation of the heating, were undertaken in full public view. The project also enabled various trademen to develop new skills in the conservation field. Our specialists are providing ongoing advice at various parts of the Tyntesfield estate, including at the Orangery and glass houses.
