Heritage Architects 

Conserving the built environment & adding to it in a considered way.

We are a specialist heritage architectural practice focused on the assessment, design and documentation of works to existing buildings. Our work centres on providing clear, practical advice for change within heritage and character contexts, informed by a detailed understanding of building fabric, history and statutory controls.

We work across conservation, adaptation and contemporary intervention, assisting clients to retain and manage cultural heritage significance while accommodating new uses, compliance requirements and functional needs. Our role typically involves heritage assessments, conservation management, impact analysis, expert advice and architectural design, ensuring that change is appropriate, defensible and aligned with recognised conservation principles.

Queensland Heritage Act 1992 ICOMOS
Cook Terrace at 249 Coronation Drive, Milton, Brisbane is a state-heritage listed row of six two-storey rendered brick terrace houses constructed in 1888–1889 for Brisbane builder Joseph Blain Cook. It was added to the Queensland Heritage Register on 21 October 1992. The terraces reflect the economic optimism of the late 1880s boom era and were built as a rental investment at a time when the Queensland Undue Subdivision of Land Prevention Act prevented individual titles for terrace houses. Within two years of completion Cook became insolvent and ownership passed to his mortgagees. By the mid-1890s the row, then known as Milton Terrace, was one of Brisbane’s more prestigious rental addresses, favoured for its Brisbane River views, breezes and proximity to the city. Over the twentieth century the building’s use evolved: subdivided into flats by 1920, known as Gloralgar Flats by the 1930s, and later converted into 27 flats post-World War II. In the 1980s it was refurbished and adapted for commercial use including offices and a restaurant. Architecturally the terrace is significant for its intact form, including rare attached timber service wings, corrugated iron mansard roof with dormers and decorative verandah detailing, contributing strongly to the Coronation Drive streetscape and riverscape.

I am an architect with practical experience in heritage conservation.
