What are zero lot line lots? - Kenekt

A zero lot line lot represents a residential property design where the house extends right to one boundary of the lot, typically a side boundary, with no setback spacing.

Overview

A zero lot line lot is a type of residential property where a house is built right up to one of the boundaries of the lot, usually the side boundary, with no setback from that side.

Example Layout

One side features 0 m setback (zero lot line); the other side maintains 1m+ setback for access and drainage purposes
Roof eaves align flush with or stay within 450mm of the boundary line

Key Features
