[1] The present Franklyn Vale Homestead was erected in the early 1870s for Mr & Mrs Edward Crace, son-in-law and daughter of Henry Mort, the owner of the property.

[1] Originally, Franklyn Vale Station was part of the 60,000 hectares (150,000 acres) Laidley Plains leasehold which, along with Beau Desert, was taken up as a sheep run in 1843 by NSW squatter JP Robinson.

This partnership was dissolved in late 1869, by which time government resumptions had reduced Franklyn Vale to about 4,000 hectares (9,900 acres) freehold.

[1] In late 1900, established Brisbane architects Addison & Corrie were commissioned to design a school room and guest wing for the homestead, and to undertake minor alterations.

Mr & Mrs Arthur Mort also improved the garden and are believed to have engaged architect Robin Smith Dods to design the summerhouse.

[1] The kitchen has exposed roof framing with timber shingles visible below corrugated iron, a central brick double fireplace and walls are single-skin.

The servants wing is also single-skin, has window hoods to the west and has a large shower head, originally operated by a cord to release tank water.

A stained timber post-and-beam summerhouse with a corrugated iron pyramid roof and ventilator is located to the southwest near the tennis court.

[1] The grounds include a small weatherboard cottage to the northwest, sitting on timber stumps with a corrugated iron gabled roof and a front verandah.

Franklyn Vale Homestead and associated outbuildings and grounds is important in demonstrating the evolution and pattern of European settlement in the West Moreton district since the 1870s.

The c. 1870s slab shed demonstrates a now rare aspect of Queensland's cultural heritage, namely the principal characteristics of 19th century bush technology and building practices, which are no longer common.

[1] The place has a special association with the life or work of a particular person, group or organisation of importance in Queensland's history.

Franklyn Vale Homestead has a special association with the Mort family and their contribution to the development of the Queensland pastoral industry since 1849.
