What We Build

Formation Building specialises Renovations, Additions & Extensions on Sydney's Northern Beaches.

Renovations

Projects typically $1M – $2M

Full home transformations for families who are staying put and building up.

Most families undertaking a whole-house renovation want the same thing: a builder they can trust with a significant decision, who keeps them informed and delivers what was agreed.

We handle design coordination, DA approvals, and every trade from start to finish. You deal with Chris directly — not a rotating cast of project managers. One point of contact, start to finish.

Second Storey Additions

Projects typically $500k – $1.5M

The Northern Beaches has land constraints that make going up the smartest move for most growing families.

Blocks on the Northern Beaches don't leave much room to grow outward. A second storey gives your family the space it needs without losing the yard — and without leaving the suburb you love.

We've added second storeys to homes right across the region. We know the structural considerations, the council requirements, and how to keep a project moving from approval through to handover. Chris's carpentry background means the detailing is done right — not just structurally sound, but finished to a standard you'll notice every day.

Extensions

Projects typically $500k – $1.5M

More space on the same block — for families who've outgrown their floor plan but aren't ready to leave the street.

Whether you need a larger kitchen, an additional living area, a guest bedroom, or a proper home office — an extension adds what's missing without the cost and disruption of moving.

We manage extensions from first conversation through to handover. Design coordination, council approvals, and every trade on site — all through one point of contact. The structural work is done properly, so the addition feels like part of the original home rather than something bolted on.
