Description
Hendre Howell is a late 17th century gentry house that stands two storeys high with attics. The original structure has a rectangular plan and features a central storeyed porch. An advanced south wing was added later, along with a service wing, creating an L-shaped layout. The building is constructed of rubble masonry that has been limewashed, resting on massive boulder foundations. It has a modern slate roof that still shows some original chamfered eaves coping, along with gable stacks and a central ridge stack with capping; the south wing has a similar stack in the southeast corner.
The porch doorway features a segmental head and is dated 1690 on the jamb. The door itself is a wide studded boarded door mounted on strap hinges. Most windows are 4-pane sashes, with 8-pane casements flanking the porch on the ground floor, while the service wing includes some modern lights.
Inside, the house has a lobby entry and an internal fireplace. The layout was partially altered with the addition of the south wing and the installation of a spiral staircase between it and the porch. Although the interior has been modernised, it retains significant features such as massive pegged chamfered collared trusses with angle braces. The sitting room showcases exposed joists, chamfered beams, and a large rough stone bressumer.
