What Is a Boundary Wall?

A boundary wall is a masonry structure built along the side or rear boundary of a property to separate it from neighbouring land. Boundary walls are typically taller than front fences and are designed primarily for privacy, security, and noise reduction.

In Brisbane, boundary walls are commonly built from brick or concrete block. Double-face brick or rendered block walls are popular because they look good from both sides, which is important when the wall is shared with a neighbour.

Boundary Wall Types

Double face brick boundary wall – both sides finished, ideal for shared boundaries.
Block boundary wall – concrete block wall, often rendered or painted.
Acoustic boundary wall – designed to reduce noise from roads or neighbours.
Retaining boundary wall – holds back soil while also marking the boundary.
Boundary wall with piers – reinforced columns for added strength on long walls.

Boundary Wall Cost Brisbane

Boundary wall costs in Brisbane range from $280 to $520 per square metre depending on material, height, finish, and whether engineering is required. A 1.8 to 2.0 metre high double face brick boundary wall is typically at the higher end of the range.

Shared boundary walls may be split between neighbours, and disputes should be resolved under the Queensland Dividing Fences Act. Our calculator helps you estimate the full cost before discussions with neighbours.
