architectural builders, melbourne
a builder for the architecture
opus formed builds architect-designed residences across melbourne, for the design practices that draw them and the clients who commission them.
the work we are suited to asks a great deal of its builder: difficult sites, complex structures, heritage fabric, joinery and stone resolved to the millimetre.
every residence is overseen by its directors, stevie hatz and andrew loucaides, from the first drawing review to handover.

working with architects
drawings in hand
where the design is resolved, opus formed is appointed to deliver the construction phase;
built as drawn, with care and technical precision.
during design
we are available while the design is still taking shape: construction insight on method, sequence, cost and buildability, shared while decisions are still open.
from first concept
for clients starting with a site rather than drawings, every commission begins with the concept service: an architectural concept matched to a design practice, costed as it takes shape and guaranteed buildable within budget.

questions from architects and clients
do you build homes designed by other architects?
yes. appointed delivery is for design practices and clients with drawings to realise; opus formed delivers the construction phase, built as drawn.
can you be involved before the design is finished?
yes. we are available during design to share construction insight on method, sequence, cost and buildability, while decisions are still open.
who oversees the build?
