Description

Maesmawr Hall is a 17th-century brick house, with substantial alterations and extensions in the 19th century, situated within expansive grounds. The brickwork is in irregular Flemish bond, topped by a steeply pitched slate roof with a lead flat. The house has two main floors, a basement, and two attic floors, and was remodeled in the Restoration style. Originally designed with a double pile plan, it featured large reception rooms on either side of a central hall, which led to a lateral staircase in a narrower rear wing, with two internal chimney stacks. Around 1850-60, the western side of the hall was altered to create a large room with a bay window overlooking the gardens, and a substantial ballroom (approximately 10 meters in length) was added to the rear. Later, minor alterations have been made. The symmetrical chimney stacks, likely rebuilt in the 19th century, rise above the roof.

The south front has seven window bays. A large, mid-19th century porch with a steep hipped roof and round-headed openings, flanked by corner pilasters, covers seven steps leading to the reworked round-headed main entrance door. A plat band runs across the facade, returning at the ends, but the eaves were rebuilt in red brick in the late 19th century and now feature moulded brick dentils, replacing what was originally a crenellated parapet. The windows are twelve-paned sashes, likely dating from the early 19th century, set within rebated reveals. There are two ranges of dormers: the lower ones have round-headed plate glass sashes, while the upper ones are smaller, with heavy segmental pediments, both supported by carved scroll brackets. Two two-story canted bay windows overlook the west gardens; one is supported by an arcaded gazebo at basement level, and a similar bay is located at the rear.

Historically, the house had a 1.2-meter-high oak roof parapet displaying 44 coats of arms of related gentry, which was removed when the roof was re-slated in 1770.

The grounds include a large lake to the north, created by Captain Lloyd Jones in 1820, followed by a later garden design by Edward Kemp around 1858.

The dining room, located to the right of the hall, boasts full bolection moulded oak panelling with matching doors, and a three-centered recess at the east end. The ceiling is divided into nine bays, dating back to the early 18th century, and is plastered with garlands and classical figures within central roundels. An open-well staircase, dating from the 17th century, rises through three floors at the rear of the dining room, featuring a deep handrail and ambitiously turned balusters between square newels. The soffite exhibits a pulvinated string and plaster garlands. Openings in the stairwell have fan-decorated segmental plaster tympana. The rear ballroom is characterized by a heavy coved anthemion cornice and a Carrara marble fireplace. The two bays within this room have plate glass sashes. The upper floors feature framed walls, and exposed timbered ceilings with chamfered beams and a form of upper crucks to the roof. In the 19th century, the layout was adjusted to create a "bachelor barrack room" for shooting parties, with a top-lit billiard room above the ballroom.
