About Build 4
We connect the intent of a design with the discipline of construction.

Our story
Build 4
Inside and Outside Limited
Established in 2020, Build 4 was formed to extend design expertise into engineering, construction and general contracting.
As a sister company of 4walls, we bring architectural understanding to the practical work of building. Our scope covers site preparation and earthworks, foundations, civil and building construction, steel structures, and equipment installation.
We see these as connected parts of a project. The ground affects the structure. The structure affects the services. The installation affects how a facility operates. Coordinating those connections is central to our approach.
Sister companies
4walls is our sister company, with a focus on architecture and design. Build 4 extends that design foundation into the delivery of construction, engineering and installation works.
Together, the relationship creates a natural connection between spatial ideas, technical coordination and work on site.

Construction is a sequence of connected decisions. We focus on the details that keep them aligned.
Keep the intended function, appearance and technical requirements visible throughout construction.
Bring civil works, structural packages and equipment interfaces into an agreed sequence.
Consider access, maintenance and practical operation alongside the construction itself.
