Located a half-mile (1 km) northeast of Rosewell and a similar distance SW of Polton, Midfield House was built originally in the 18th Century but rebuilt following a devastating fire in 1912. Home to coal-baron James A. Hood (1859 - 1941), who lost his daughter Margaret in the fire. The reconstruction was carried out between 1914 and 1918 by noted architect Sir Robert Lorimer (1864 - 1929), retaining the original Georgian style, while improving the south-facing side and adding internal grandeur, including details featuring children, reflecting Hood's loss. Lorimer gave the southern aspect house an Italianate flavour, with a water feature and a distinctive loggia, similar to that constructed by him at Ardkinglas (Argyll and Bute).
The house was for a long time a children's home, but in the late 1980s was converted into private flats.
