The Marine Engine House
Constructed in 1894, the Marine Engine House, previously named the Ferry Lane Pumping Station, was built during the development of the reservoir complex. The structure is relatively complex in form, but consists primarily of a two-storey building with a single storey building attached to its northern side. To the west of this is a further single storey building which includes, on its western side, the base of a now-demolished chimney stack. The Marine Engine House is constructed throughout in brick and architecturally is in the simplified Italianate style much used for Victorian industrial buildings, with semi-circular heads to all of the principal door and window openings.
Roofs are generally finished in plain clay tiles with extensive use of patent glazed roof-lights and ridge lights in the single storey sections. The roof of the Engine House is pitched at around 45 degrees, and is half-hipped at its northern and southern ends. Doors and window frames are in painted softwood. Despite the missing chimney, and some external alterations, the building is still an imposing piece of Victorian industrial architecture.
The Engine House is now a visitor centre with a café, shop, and exhibition space.

The Coppermill building is Grade II Listed and has undergone a number of alterations over the centuries, including the addition of an Italianate tower in 1864. The mill at

From 1659 until 1703, the mill was known to have been used as a paper mill with the adjacent stream being referred to as the Paper-mill River. However, in 1699 the adjacent marshes are noted to have been referred to as Powder Mill Marsh which questions the use of the mill and suggests that it may have been used in the production of gunpowder for the

between 1642 and 1651. A number of gunpowder mills operated in the Lower
Lee Valley, suggesting that the mill may have been used as such during this time.
Accounts from 1703, 1710, 1712 and 1718 record the mill being used as a leather mill, with Pierre Montier, a skin-dresser, first referred to as ‘the Miller’ in 1703 to be followed in turn by Peter Lefevre in 1711 and Daniel Lefevre in 1713.
The mill was described as an ‘oyl mill’ until 1806 when it was rebuilt and purchased by the British Copper Company in 1808.
