Accessory buildings add usable space, rental income and long-term value to a property. but only when they're engineered and detailed properly. South Coast Remedial designs and builds detached structures that match the host dwelling, comply with the NCC, and stand up to the coastal weather we deal with every day on the Illawarra.
From a compliant secondary dwelling through to a workshop, pool house, studio or oversized garage, we handle the full build: site assessment, certifier liaison, slab and footings, framing, cladding, waterproofing, services and finishes. One team, one point of contact, one warranty.
What's Included
Every accessory buildings engagement covers the scope below, adjusted to suit the specifics of your project.
Secondary dwellings & granny flats
Self-contained accommodation built to current SEPP and BASIX requirements, with proper acoustic, fire and waterproofing detailing.
Studios, home offices & cabanas
Insulated, lined and serviced spaces designed for year-round use. including data, power and split-system provisioning.
Garages, carports & workshops
Slab-on-ground or suspended structures with engineered footings, roller doors and durable cladding systems.
Pool houses & outdoor rooms
Wet-area-ready structures with correct falls, membranes and ventilation to prevent the moisture issues we routinely remediate elsewhere.

Frequently Asked Questions
Do I need a DA for a granny flat?
Often a Complying Development Certificate is faster and cheaper, but it depends on the lot size, frontage and overlays. We'll assess that on the first visit and tell you straight.
How long does an accessory build take?
A standard 60sqm granny flat typically runs 14,18 weeks on site once approvals are in place. Garages and studios are quicker.
Can you match the existing house?
Yes. we'll match cladding, roof profile, fascia and window suites so the new structure looks intentional rather than tacked on.
