Seagren's Building is a heritage-listed workshop at 124 Charlotte Street, Cooktown, Shire of Cook, Queensland, Australia.

[1] This two-storeyed timber and galvanised iron building was constructed in the 1880s for Cooktown cabinet maker and furniture dealer, Pher Erick Seagren (Sjorgren), who acquired the site (allotment 11 of section 3, parish of Cook) in 1880.

Photographic evidence reveals that the building was extant by the late 1880s at least, although the northern side verandah was not added until around the turn of the century.

Intending to join in the Palmer River goldrush, Seagren travelled to Cooktown in February 1874, but chose instead to establish himself in his trade at the burgeoning port.

He was one of the town's earliest citizens, and according to local tradition his son, William Erick Endeavour, was the first white male born at Cooktown, on 26 August 1874.

In August 1889, Seagren advertised as a cabinetmaker and upholsterer, whose furniture warehouse and china and glass bazaar was located near the Queensland National Bank in Charlotte Street, the principal thoroughfare of Cooktown.

[1] By the early 1900s output from the Palmer goldfield was declining, and Cooktown's significance as a regional port correspondingly decreased.

Seagren's contribution to his community has been described as follows:[1]"He has laboured for the improvement of the town with unsparing energy, and the excellent condition of the streets, footpaths, and other public works is due to his progressive methods when mayor.

[1] In 1924 title to the Charlotte Street property was transferred to Seagren's only surviving child, Mrs Gertrude Blanche Muller, and following her death in 1949, to her children Mrs Malvine Rosetta Blanche Johnson and Erick Seagren Muller, who sold the building in 1952.

Little has been recorded of the use of the building between the mid-1930s and the late 1960s, when Margaret Edmonds and Adrienne (Bobby) Gravenor established a newsagency, boutique and tourist information centre in the downstairs shop.

The remainder of the building is clad in fibrous cement sheeting either replacing or covering original corrugated iron.

[1] A two-storeyed verandah with cast iron balustrade at first floor level runs along Charlotte Street and returns along the northside.

[1] A shop is situated on the ground floor that runs the depth of the two storey section and has a set of French doors at the entrance with large timber-framed windows each side.

The building remains a rare example of its type: a two-storeyed late 19th century North Queensland shop-house constructed of timber framing and galvanised iron cladding, with front and side verandahs to the upper level, illustrating the adaptive use of portable building materials and of design in a remote tropical locale.

[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.
