11/275 North Mymms Park with adjoining garden walls 6.2.52 and ha ha


Country House. Built for Henry or Sir Ralph Coningsby about 1600, probably before 1596. Altered on courtyard side in 1846-7 by E Blore, and extended on same side in 1893-4 by Sir Ernest George and Yates. H plan with long courtyard arms. Red brick with burnt header diaper patterning. Stone dressings. Plain tile roofs. 2 storeys and attics. 7-window entrance front has gabled projecting ends and flat-parapeted porch bay, all projections with flush stone quoins. 4 and 5 light windows with 2 transoms. Restored fluted Doric columns to porch; triglyph frieze and foliate spandrels. Restored cement parapet to whole front. NE and SW elevations are each 5 windows and have 3-light mullioned and transomed windows. The NE side has a central C17 style stone Doric doorcase with fluted columns, bracketed cornice and scrolled overthrow; probably late C19. This side has 3 gabled attic dormers retaining original stone mullioned windows. SW elevation has 2 similar dormers. SE courtyard elevation is mainly 1846-7 restored brickwork and shows tall red brick stacks with Tudor style square and polygonal shafts, those of NE side with C17 bases. Main elevation has projecting outer gable ends and large central gabled oriel window, mullioned and transomed in 25 lights. Stair window to right. The side wings were built forward with corridors but show single gabled attic dormers of original build each side. The wings terminate in square angle blocks incorporating 3-storey stair turrets with copper ogee domes. Each wing has gable ends on SE elevations. The windows throughout the house are diamond leaded casements.

Large extension to SE wing of 1893-4 is 1-2 storeys. Its most important feature is a loggia with 3 arched lights. Barrel- vaulted interior with mosaic patterning. Richly carved marble frieze and arcade of Corinthian pilasters. Shallow niches. Elaborate bronze door on SE. It joins with SE courtyard walls, corner gazebos and gates. Red brick with stone banding. The gazebos have stone square domes with cupids at angles and paired Ionic pilasters at the corners. Wrought iron double gates with wrought iron railings. These connect at SE corner with a C18 garden wall which runs for about 130 metres on the NW side of the path to the church. It has at its centre a wrought iron gate in an arched opening. It joins with a semi circular 'ha ha' with red brick walling of the same date, and this connects on the SE side of the main entrance road with a C17 stretch of wall, joining near the house with the front garden walls which appear to date c.1846. They form two terraced gardens and have richly detailed wrought iron gates near the house. On the SW side of the house are three walled gardens of the C18 and C19, containing rose beds laid out by William Robinson in the late C19.

The interior of the house is mainly c.1893 in Elizabethan revival style. The entrance hall has a large French chimneypiece of 1515 with rich guilloche and fluted decoration. The SW ground floor room retains complete original panelling and chimneypiece, the latter with an inserted crest dated 1655, its surround in stone and the overmantel in two tiers of three ornamental panels. Rear central room has Jacobean style minstrels' gallery and newel staircase, and the upper front room a chimneypiece with Elizabethan fireback.
