The building was designed by John Currie, an Auckland architect who intended it to be made ‘absolutely rat proof’ by placing it on solid concrete foundations. The builder was Mr George Smith, local sawmill owner and prominent Gisborne citizen. Upon completion the Poverty Bay Times declared the building to be a ‘most pleasing design’ and ‘a fine addition to the town’. Lancaster House is a two storeyed building of plastered brick with concrete foundations, corrugated gabled roofs and generous glazing. In 1933, after the Napier Earthquake in 1931 and further seismic activity, several alterations were made. The neoclassical façade was simplified by the removal of the brick pediments and parapet, which were replaced with a low structure of reinforced concrete. The ground floor and upper floor cornices were altered or removed, and consoles on ground floor pilasters also removed. The building now has little ornate detail; however the pilasters, rusticated on the ground floor, are prominent. The exterior was painted in 1966 and refurbishment in the mid 1970s included redecoration and the erection of some internal walls. The building had major cracking to the exterior walls, as a result of the December 2007 Gisborne earthquake, which necessitated extensive repair work and structural strengthening. This included new foundations (11000mm wide x 600mm deep) constructed against the edge of the existing building's foundations. Some original interior features remain, particularly in the entrance hallway, which has a tiled floor and rimu lined walls. The flight of four steps at the entrance is built of Melbourne blue stone. An impressive, elaborately constructed main stairway with wooden balustrade, leads off from the space immediately in front of the entrance. The original vault remains, featuring early graffiti, a social history of dated signatures of former staff since 1926, scratched into the surface and retained during restoration. The pressed metal ceilings replicate the original decorative patterned metal ceiling recorded but destroyed during strengthening work. In September 2010, a lantern roofed brick storage building to the rear of Lancaster House and associated with LD Nathan’s operation, was demolished as part of site redevelopment unrelated to Lancaster House.
A now simplified neoclassical design, Lancaster House has aesthetic significance as part of Gisborne’s heritage streetscape; it is one of a cluster of 11 substantial, commercial scale heritage buildings on Customhouse Street and Childers Road, including the USSCo building. Lancaster House has architectural significance as a building designed by John Currie; the firm of LD Nathan were his major client and Lancaster House is a now rare surviving example of a commercial building commissioned by LD Nathan and designed by him. The high quality of the finishing materials in the entrance vestibule is a surviving important feature of the building’s architecture. The building has historical and social significance through being erected by the prominent national firm of LD Nathan and Co and represents their substantial investment and diversified business interests in provincial towns in the early 1900s.The building has social significance as it was constructed by a prominent local builder, in the midst of what has been a continuously popular commercial business district since the 1890s. It was considered to be fine addition to the town. Further historical significance is exemplified by the fact that the building has survived several large earthquakes, and the physical character of the building’s façade detail tells that story of survival through it having been pared back in response to each episode.
