Border Archaeology (BA) was instructed by Capital Homes (Southern) Ltd to undertake a programme of Archaeological Standing Building Recording at The Lodge, 233 Brook Lane, Sarisbury Green, Southampton SO31 7DQ, with regard to a planning application relating to the proposed demolition of the property (Fareham Borough Council Planning Ref. P/19/1020/FP) and the construction of a replacement dwelling with detached garage. It was not possible to undertake a detailed recording of the building to Historic England/RCHME Level 3 as originally stipulated by the Conservation Officer at Fareham Borough Council, due to the fact that the interior of the main portion of the building could not be fully accessed for demonstrable health and safety reasons due to its very poor structural condition, with most of the roofing having collapsed, together with the suspended timber floors.Consequently, a limited drawn and photographic record has been compiled to Historic England/RCHME Level 2,utilising existing survey plans and photographs of the building where available. The limited programme of ASBR undertaken by Border Archaeology with regard to The Lodge, 233 Brook Lane, Sarisbury Green, Southampton SO31 7DQ, supported by cartographic and documentary research, has reached the following conclusions briefly detailed below: The Lodge is a single storey rectangular brick gabled structure of mid-19th century date, built as a gate lodge at the SE entrance to the grounds of Coldeast House, a substantial country house built between 1846 and 1851 for Arthur Hornby, a wealthy landowner and horse dealer.

It is built in a restrained Picturesque style with pedimented gables and eaves cornices with dentilled decoration; the fenestration consists of segmental arched and round arched casement windows with flat-arched windows in the principal SW-facing elevation, flanking the ornamental wooden entrance porch. Attached to the rear of the house is a modern flat-roofed extension, housing a kitchen and bathroom which appears to have been built in the mid-1950s when the house was refurbished. The interior of the building appears to have been extensively refurbished in the mid-20th century, probably contemporary with the addition of the rear kitchen/bathroom extension. The fireplaces appear to have been replaced or blocked up and the interiors of two of the rooms clad...
