TwoFiveFive Architects has designed Three43onB in Cape Town, South Africa.

Rising on the Atlantic coastline, Three43onB reimagines coastal living through refined, context-driven architecture.

Positioned in the urban fabric of Sea Point, it engages its surroundings through thoughtful density and human-scaled design.

A modulated facade adds depth, while glazing, screened balconies and articulated frames maximise light and privacy.

Efficient interior layouts balance openness and environmental performance with durable, coastal-resilient materials.

At ground level, an active edge strengthens walkability and community connection.

Three43onB offers a crafted, considerate presence that enriches its neighbourhood through people-focused design.
