Service rooms and kitchen and scullery are grouped round a side entrance at the end of the passage with back stairs to first floor.

All original doors are retained, 2 panelled doors with brass fittings. Parquet floors to hall and dining room. Moulded plasterwork to ceiling cornices and roses. The lounge has a low stone fireplace with Tudor arch; leading off is the originally part-glazed loggia now a wholly glazed conservatory. The staircase is panelled and lit by a large Elizabethan-style multipane 3-tiered window; a huge gilded mirror adjacent was part of the original fitting. Dining room fireplace is of marble with polished wood surround. To rear is a 'butler's pantry' retaining all its original glazed cupboards. Upstairs the airing cupbaord and a bathroom retain their original copper heating pipes. Roof space is divided by brick walls; trusses have collars, ties and queen posts with raking struts.
