TIMBER & THATCH
Reed and timber AS CONSIDERED ARCHITECTURE
Natural materials such as thatching reed and structural timber offer more than visual warmth. Across four projects, JNA Group shows how craft, climate performance, and intentional architecture can work together.
Thatching reed and structural timber have more in common than many architects may first assume. Both are natural materials selected for climate performance, durability, and their ability to bring warmth and character to a building.
Species such as SA poplar, blue gum, and sugar gum offer lower-carbon structural options, while properly installed Cape thatch provides insulation and longevity, as well as a strong connection to South African building traditions.
Few South African construction companies have developed depth in both timber and thatching. JNA Group says its work across four very different projects demonstrates the value of bringing the two disciplines together.
HOUSE OF DRAGONS, LOWVELD
In the Lowveld, architect Andy Horn designed an off-grid eco home around a framework of blue gum timber( Eucalyptus globulus), an invasive species cleared from riparian environments, giving its use an ecological logic aligned with the project’ s wider ambitions.
A planted green roof, rammed earth walls, cob floor, and eco pool complete the picture. Inside, exposed trusses and ceiling members are left visible, with the grain and joinery forming the home’ s primary aesthetic. Engineering the complex roof geometry on a remote site required a high level of problem-solving.
