149 Featherston, Wellington banner

The refurbishment of 149 Featherston Str, Brandon House in Wellington, facilitated halving the embodied carbon compared to a new low-carbon build. The original 1960s Leaders Building was fully stripped back to its concrete structure and an additional three levels were added in timber construction, taking the whole building to 11 storeys. The top storey has penthouse office accommodation with views to the Wellington harbour.

The new bronzed Low-E glass curtainwall, Thermosash PW1000 Unitised flush glazed, wraps around the building like a skin, creating a smooth glass vertical facade. The corners of the building, comprised of curved glass, provide a contemporary sculptured effect to the office tower. Thermosash also installed PW1000 suite to the street level shopfront, louvres, auto and hinged doors, aluminium cladding, frameless shopfront, as well as our Sierra Suite manual sliding doors to the deck area.

Brandon House by Studio Pacific Architecture won the Commercial Architecture award in the 2022 Wellington Architecture Awards.

Thermosash has reclad and refurbished many commercial facades across New Zealand, bringing new life to building structures by engineering high performance solutions with trusted building envelope systems. Our systems are Unitised TM which enables us to close in buildings rapidly and save on programme time.
