Eagle House including balustrade two yards in front of south elevation

Eagle House, now converted to flats, is a late 17th and early 18th century house on the west side of Northend in Batheaston. It was remodelled in 1724 (with the date recorded on an inner wall, formerly the west gable) and again in 1729 by John Wood the Elder, for whom this was his first known house and work in the Bath area. The building was extended between 1906 and 1908 by Mowbray Green of Bath for Colonel Linley Blathwayt.

The house is built of coursed rubble with ashlar quoins and dressings, the top two courses below the eaves being of ashlar, indicating the roof was raised at some point. It has a half-hipped slate roof and ashlar stacks with a moulded cornice. The structure comprises two storeys with a basement and attics lit by pedimented dormers.

The south (garden) elevation displays five bays, with an additional two bays forming the 1906–1908 extension to the left. The windows are twenty-four-pane glazing bar sash windows in architraves; those in the extension have eighteen panes. A continuous moulded string course runs above the ground floor. The central feature, clearly the work of John Wood, is a Venetian window on the first floor with two outer blocked lights and a central triple keystone that rises to join the cornice. Below this is an Ionic doorcase with heavily banded columns and a pediment, with a panelled door. A pierced balustrade, situated two metres in front of the south elevation, runs along the terrace.

The east elevation comprises three bays. The centre bay, by Wood, is slightly advanced with quoins; it features a blocked window on the ground floor and a shell-headed niche containing an urn on the first floor with a central triple keystone rising to form the base of a pediment. The pediment's tympanum bears a cartouche dated 1729, and a coarsely cut eagle with spread wings surmounts it. The outer bays contain two twenty-four-pane glazing bar sash windows in architraves, with a continuous string course running across all three bays.

Inside, remains of an early 18th-century staircase survive, featuring turned and twisted balusters and panelled plasterwork at its top with shell-headed niches. A ground floor room (Flat 1) retains an early to mid-18th-century fireplace with Ionic pilasters, an overmantel and decorative surround.

Eagle House is a highly significant provincial baroque building and represents John Wood the Elder's first known architectural commission in the Bath area.

The house holds considerable historical importance as a centre of suffragette activity. It was the home of Colonel Linley Blathwayt, his wife Emily, and their daughter Mary, all strong supporters of women's suffrage. Mary and Emily joined the Women's Social and Political Union (WSPU), the militant suffrage society formed in Manchester in 1903, and became close to Annie Kenney, the WSPU's Bristol organiser. Kenney became a regular visitor to Eagle House, using it as a place of retreat when exhausted from political campaigning. The house became widely known among suffragettes as a welcoming retreat; visitors came to enjoy the Blathwayts' hospitality and access to the family's motor car, with some using it as a base for propaganda work in the south west, whilst others came to recover their health after imprisonment. Leading suffragettes including Emmeline and Christabel Pankhurst, Elsie Howey, Charlotte Despard, Constance Lytton, Charlotte Marsh and Emmeline Pethick Lawrence all spent periods at Eagle House. Evenings often featured singing and games, and visitors were encouraged to plant trees in an area of the grounds named 'Annie's Arboretum' in honour of hunger-striking suffragettes. At least 47 trees were planted, each recorded photographically by the keen amateur photographer Blathwayt. Emily resigned from the WSPU in 1909, dismayed by the escalation of the Union's violence, though she continued to welcome militant women to the house. Mary resigned from the Union in 1913, possibly following a local suffragette arson attack. The arboretum was demolished in the late 1960s, though one tree—an Austrian pine planted by Wimbledon suffragette Rose Larmatine Yates—survives.
