Number 2 Old Engine Houses, including marker stone

Number 2 Old Engine Houses is a house, originally built in 1825 as an engine house for the Brusselton inclines, which were part of the Stockton & Darlington Railway. The inclines were operational between 1825 and 1831, and the engine house was later converted into a domestic dwelling after 1831.

The house is constructed from tooled and squared local sandstone, with a Welsh slate roof and rebuilt modern brick chimney stacks. The plan features a central entrance with a staircase rising from the front door.

The two-storey house has a west-facing single-pitch roof. The west gable of the adjacent building, Number 1 Old Engine Houses, extends above the rear wall. The north and south end walls are stone-coped and feature centrally placed tall chimney stacks. The elevations are quoined.

The west elevation is symmetrical with three bays. A central four-panel door is flanked by two-over-two pane horned sash windows. The first-floor windows are slightly shorter, with the central window being three-over-three pane. All windows have monolithic lintels and slightly projecting sills. A late 20th-century single-storey range of outbuildings, built in matching materials and style, abuts the south end of the west elevation.

The north elevation contains a tall, round-arched opening, now infilled with stonework. The arch is formed with projecting key stone voussoirs. This opening is believed to have accommodated the steam winding engine used for the inclines.

The south elevation is largely blind, except for an infilled circular opening of about 1m in diameter, positioned around the level of the west elevation's eaves. This is interpreted as a former window opening. The quoins on this elevation butt up against the rougher walling of Number 1 Old Engine Houses. The upper part of the west gable wall of Number 1 is built on top of the rear (east) wall of Number 2.

A stone-built garden retaining wall extending west from the north elevation includes a reset marker stone inscribed "S 20½", indicating the mileage to Stockton.

The surrounding area is designated as a scheduled monument.
