In the summer of 1876, with almost 30 families facing the future without a local education programme, Fr Michael Barry from Saggart was approached about the possibility of establishing a school in Brittas.

It was put on the market in 2013, and eventually sold in January 2018,[7][8] when it was bought by two County Dublin residents who retained its name and vintage charm.

[9] In 2021 a planning application was made to convert part of the ground-floor into two apartments but this was refused by the South Dublin County Council.

[citation needed] St. Brigid's Nursing Home was a facility caring for long-term female residents on a 26-28 acre site[11] just north of Brittas in the townland of Crooksling.

[6] St. Brigids' was first acquired by the joint hospital board of Dublin County Borough in 1911 under the 1908 Act[12] and was originally opened in June 1911 as the 'Crooksling Sanatorium', for the treatment of patients with tuberculosis.

In 1912, Thomas Francis McNamara was appointed architect to the Dublin Joint Hospital Board[14] and designed many additions to the site including a new day room, doctor's residence, nurses' quarters etc.

[13] By the late 1950s tuberculosis had effectively been eliminated as a major health risk in Ireland,[15] and the site's function gradually changed to that of a nursing home.
