Description
Porth-en-Alls Lodge, dating circa 1910-1914, served as a chauffeur's lodge to Porth-en-Alls house. Designed and supervised by Philip Tilden, a relative of T.T. Behrens who built the main house, the lodge is constructed of killas and granite rubble with granite dressings. The roof is covered in stone slates laid in diminishing courses, with the ridge following the segmental plan of the main house and having half-hipped ends. Dressed stone chimneys are positioned over the front wall.
The lodge’s plan forms a segment of a circle, creating the exterior part of a circular courtyard connecting to Porth-en-Alls. It is built into bedrock at the rear (west), with rooms radiating on the ground floor. A central doorway leads to basement steps ascending to a rear passage providing access to all rooms. To the right of the passage is a dining room, followed by a kitchen and a WC. A reception room sits to the left of the entrance, with a principal bedroom likely originally the reception room further left. Additional bedrooms are located in the attic, accessed by a steep staircase.
The exterior is single-storied plus attic, over a basement. The east front is symmetrical, with two windows arranged on a convex facade. A moulded doorway is centrally positioned in the thicker basement wall, flanked by square-on-plan terminal buttresses. Double flights of stone steps ascend to the doorway, which is topped by a gabled attic stair turret with a small, lozenge-shaped window. The ground floor walls are slightly set back on either side of the turret, with windows filling the spaces between the turret and the two lateral chimneys. Wide windows are located under the hip at each end. All the windows feature original wooden casements with glazing bars.
The interior remains virtually unaltered, retaining original carpentry and joinery, with structural elements freely exposed. Rubble and earth retaining walls, alternating vertical and horizontal courses are positioned at either side of the front, with a flight of dressed granite steps on the far right.
