Harleyford and Whittington House

This conservation area covers two grand riverside estates and was designated in 1992. To the west lies the Wittington estate, whose buildings are now occupied by office use.

The main house is listed Grade II*, and dates from 1898. It was built by Sir Reginald Blomfield for Lord Davenport, in the William and Mary style.

The adjacent coach house is also listed. There are extensive landscaped gardens. To the north lies a small enclave of service cottages and barns adjacent to the Henley Road. These pre-date the main mansion. The Lodge Cottage on the main road is also listed and is in typical Victorian estate style.

The eastern part of this conservation area covers Harleyford Manor. This is a mid to late 18th century landscape park and pleasure ground, possibly by Capability Brown, surrounding a Grade I 1755 Thames-side villa. The house was designed by Sir Robert Taylor, of redbrick, and was his first country house, of a pioneering compact and adaptable design.

The riverside areas comprise the pleasure gardens, main house and kitchen gardens, and now include a chalet and caravan park, and lies in the floodplain.

To the north the valley side rises steeply for 30 metres, before reaching the plateau, which comprises a mixture of open ground (now a golf course), and woodland. There are six listed buildings in this part of the conservation area.
