Tirley Garth is a large country house some 2.5 miles (4 km) to the north of Tarporley, Cheshire, England.

[1] The building of the house began in 1907 for Bryan Leesmith, a director of the chemical firm of Brunner Mond, the architect being C. E. Mallows.

[4] Irene was a member of the campaign for Moral Re-Armament (MRA) and in 1940 she invited the organisation to move here to shelter from the war.

[5] After the war Irene bought the house and grounds from Imperial Chemical Industries, the successors of Brunner Mond, and presented it to MRA, establishing the Tirley Garth Trust in order to preserve it.

The central bay has a large semicircular projection in two storeys with an eleven-light mullioned and transomed window behind which is the great hall.

To the east of the house terraces lead to two enclosed lawns and a small octagonal garden containing a fountain.

From the north of these a path leads to the Round Acre, a circular area initially intended for the kitchen garden, now planted with flowering cherry trees.

[11] The lodge house at the southern entrance, designed by Mallows, is also Grade II listed.
