High Wych Grange

High Wych Grange is a house, built in 1862 by G E Pritchett, originally designed as a vicarage for Rev H F Johnson in the newly created parish. It was sold in 1929 and renamed. The house is constructed in a scholarly Gothic style, facing west, and is designed to resemble a tall medieval hall-house with two-storey gabled cross-wings at each end. The use of stone is unusual for Hertfordshire. The construction incorporates limestone dressings, coursed rubble walling, and white brick for service areas, decorative chimneys, and single-storey outbuildings to the rear. It has a steep tiled roof, with a large timber-framed 'louvre' above the center of the hall range, featuring small windows on the sides.

The west front includes a single-storey projecting entrance porch in ashlar with heavy double doors under a segmental arch and four steps. A tall mullioned and transomed three-light stone window rises through two storeys. The right-hand cross-wing features heavy bargeboards with trefoil cusped holes and a large three-light mullioned and transomed window on each floor. The left-hand cross-wing is more elaborate, with a different pattern of cusping on its bargeboards, a three-light window above and a hipped-roofed projecting stone square bay on the ground floor with corresponding side lights. Picturesque chimneys top the side walls of the cross-wings, with stepped corbelling at the base of the north chimney and tumbled brickwork higher up. The south-facing garden front has one and two-light mullioned windows with relieving arches above, and a pair of long, four-light windowed, hipped-roofed stone bays on the ground floor, flanking a recessed pointed niche enclosed by a timber screen with French doors and three stone steps down to the garden.

White brick service areas overlook an east service yard with steep, tiled-roofed, gabled outbuildings extending in an L-shape. The interiors feature high ceilings and plaster cornices with wide plain chamfers flanked by smaller mouldings. A staircase rises in the west 'hall range' lit by the tall window.

High Wych Grange is a striking 19th-century stone house designed to resemble a large medieval hall-house, originally intended for a wealthy vicar. It forms an essential element within the group of new parish buildings erected by Pritchett for Rev Johnson between 1860 and 1862.
