Number 1 Old Engine Houses, including steps and retaining wall

Number 1 Old Engine Houses is a house originally associated with the engine house for the Brusselton inclines, built in the mid to late 1820s for the Stockton & Darlington Railway.

The house is constructed from coursed local rubble stone, with the west gable above the roofline of the neighbouring property made of rendered brickwork. It features a renewed pantile roof and a rebuilt modern brick chimney stack. The layout consists of two rooms deep, with the staircase rising from the front door.

This two-storey house has east and west gables that are raised and stone coped, with the west gable featuring a four-flued ridge stack that retains two chimney pots. The elevations are asymmetric, and the windows vary in size, all being two-over-two pane horned sashes with plain monolithic lintels and slightly projecting sills.

On the south elevation, the front door is located to the far right and is a four-panel door with a simple three-light overlight. To the left of the door, there is a single window, with two slightly narrower windows above on the first floor. There is a butt joint with the quoins of the attached property to the west, which is 2 Old Engine Houses, listed separately. The upper part of the west gable is built on top of the side wall of this neighbouring property.

The east elevation is mostly blind, featuring only a single, centrally placed first-floor window and a single door on the ground floor, offset to the right. This door has a three-light overlight and an enclosed lean-to timber porch.

On the north side, the ground surface is lower, as this side of the building is on the original railway track bed. As a result, the single window on the ground floor and the two first-floor windows appear raised. A Royal Mail post box is set into the wall, relative to the lowered ground surface.

There is a straight flight of stone steps against the north elevation leading to a raised garden to the east of the building. This garden is retained by a substantial stone wall that incorporates several re-used sleeper stones. The surrounding area is designated as a scheduled monument.
