Rear extensions
Rear extensions in Melbourne — open-plan living, honest to the original home.
The rear extension is the most common upgrade for Melbourne's single-fronted terraces and weatherboards. Pushed the right way, it opens the house to light, garden and a proper kitchen without ever touching the street elevation.
The RenoWorx rear extension
Contemporary rear, sympathetic street. It's the classic Melbourne move for a reason.
A rear extension replaces the dark, cramped rear lean-to that most period homes end their days with — bad kitchen, laundry off the back door, worse bathroom. We design the new rear as open-plan kitchen, dining and living, connected to the garden with real glazing, and detailed so the tie-in to the original house reads seamless. Most rear extensions we build don't touch the street elevation at all, which usually keeps the planning conversation with council simple.
