Lodge, Midfield House, Lasswade

Midfield House Lodge, designed by J MacIntyre Henry in 1891, is a single-storey building with an attic and features an asymmetrical four-bay layout. The lodge has half-timbered and pierced M-gables on the northwest side and a Dutch gable on the northeast, with a later harled addition on the southwest. It is constructed from snecked and stugged ashlar sandstone, with droved ashlar dressings and window tails, raised cills, and timber canted windows at ground level. There is a cill course in the attic that separates the half-timbered gables from the stone wall below, and the building displays long and short quoins.

On the northwest elevation, the bays are arranged in a 3-1 configuration, with the single bay set back on the outer left. The three-bay group includes a four-light canted window on the ground in the bay to the left of center, with a gablehead window above it. There is an architraved and corniced window at ground level in the bay to the left, and another four-light canted window in the bay to the right of center, also with a gablehead window above. The single bay on the outer left features a part-glazed timber panelled door that is set back.

The northeast elevation consists of two bays, with a Dutch gabled bay to the right of center. There is a four-light canted window at ground level in the bay to the left of center, with a window above in the gablehead. A window is located at ground level in the bay set back to the right of center.

The southwest elevation includes a three-bay harled gabled addition that is advanced to the right of center, featuring a modern door in the central bay and a gablehead window above. There is a window in each flanking bay. To the left of center is a single bay with a gabled end from the original lodge, which has a window at ground level and another in the gablehead above, along with a gablehead stack.

The lodge features a variety of glazing patterns, including four-light oriel windows at ground level on the northwest and northeast sides, bipartite fixed windows with small-pane top lights on the northwest, and skylights in the addition. The roof is covered with cat slide grey slate, has deep eaves with exposed rafters, and is topped with red clay ridges and spike finials. There are ashlar skews and an ashlar coped gablehead stack on the southwest, as well as an ashlar coped stack at the center of the M-gable. The building also has cast-iron rainwater goods.

The gatepiers and boundary walls consist of square-plan ashlar sandstone gatepiers topped with corniced caps and ball finials. The boundary wall is made of sandstone rubble with a ridged ashlar coping and decorative wrought iron railings.
