The house and surviving farm buildings at Craig Arthur form a `U' shape group of mid to late eighteenth century buildings, open to the north-west facing a walled access track (see first-edition Ordnance Survey 25" map). The brick-built two and a half storey house has a date-stone inscription `1776 built Hester Norman'. The Norman family were agent and owners of the Trelogan lead mines and it seems likely they invested their money and either built new, or rebuilt, the present buildings at this period.

The farm-buildings at the south-east side are stone-built, consisting of a three-bay corn barn and lofted stables adjoining the brick-built house all in-line. The south-west side has been converted to domestic accommodation, but was a two-storey cart-house and bake-house with external stone stairs at the south-east gable-end. The cart-house entry is still visible as a blocked, off-centre arch, in the north-west gable-end. The north-east side has been replaced by a twentieth century building, and a parallel cow-house range beyond has been demolished, as has a loose box against the wall between front garden and yard (see first edition Ordnance Survey 25" map).

The corn barn has opposed central arched doorways and two-tier ventilation slits. Its slate-roof is supported by oak timber collar-trusses with two pairs of side-purlins and later vertical pine timber ridge piece. The first stable has a central entry flanked by windows all now with timber lintels. Internally there are transverse square-section ceiling-beams with a rectangular-section joist to the loft. The position of a hay-drop against the rear wall and the ceiling-beams indicates there were stalls for eight horses. It has the same roof-trusses as the barn. The adjoining stable is partly collapsed, formerly with a loft, arched entry and small window to the left front.

The `U' shape group of buildings retain a walled garden in front of the house and a walled cattle yard in front of the barn and stable. A large walled kitchen garden is located against the cart-house/granary and the track wall.
