Middlebrook is a suburb that spans the boundaries of Horwich and Lostock in the Metropolitan Borough of Bolton, Greater Manchester, England (historically a part of Lancashire).

A cellar appears to have been located under the northern service bay and later GMAU investigations would infer that this used to be occupied by a small water wheel (for grinding domestic crops?)

Something of a rebuild appears to have happened around 1666 and was possibly refaced or altered in 1811, as evidenced by the semi circular datestone over the adjacent cottage which dates from 1811.

Floorboards upstairs in the main range were butt jointed and wide, of random size; some doorleaf stiles and rails were reed moulded and mortise framed and simply panelled, indicating 17th century origin.

The floor over the 'housebody' was a much later addition to the original, being supported off separate beams running parallel to the long walls and resting on inserted brackets or 'corbels'.

Much of the original timber framing remained within the rear 'outshut' including a former unglazed window complete with Oak stave mullions.

the timber framing was set upon a high sandstone plinth, the same remained on the main frontage under the brick infill to the 'parlour' bay.

There is a case for supposing that these were taken from the timbers replaced by the later stonework, and one beam in particular hinted at coming from the old north gable truss chord, due to its size and moulding.
