Noddsdale House is a converted farmhouse, which is shown on the earliest maps of the area. Its Tudor details were designed and incorporated by James Miller around 1900 and subsequent alterations designed by T.G. Abercrombie were added in 1910 and again further changes designed by Fryers and Penman in 1923.

It is a Grade B listed building. Close to it and built in a sympathetic style is a small property, also listed, built to house two Gilkes Pelton wheel turbines installed in 1927. This installation, which supplied the House and four cottages with 110V DC lighting, was the third Hydro extension on the site.

With the need to rewire part of the house, the time had come for considering the refurbishment or replacement of the existing plant and so in December 2006 Inter Hydro Technology were invited to meet with the owners of Noddsdale house, introduced to the old hydro scheme, and asked to present proposals for upgrading it to include the possibility of connection to the grid.

The final scheme devised by IHT sees a new powerhouse set below the old house and powerhouse. Located in a natural bowl the powerhouse is very difficult to see in the landscape.

The existing intake has been improved and reused; inflow has been augmented by additional flow abstracted from Noddsdale Burn under a variation to the

existing abstraction licence. A new intake weir had to be designed and constructed in the Noddsdale burn to capture water from it and a pipe laid through woodland under the estates management and control to convey this additional water to the small reservoir at the head of the pressure pipe.

The old pipeline was inspected and a short length through the impounding dam retained for the new scheme so as not to risk disturbing the dam. From the dam a new 225mm HDPE pipe runs the entire distance, approximately 900m, to the powerhouse.
