- Increasing Property Value: Adding a laneway house enhances a property’s appeal and market value, making it a smart investment for homeowners.
Laneway houses are particularly popular in urban areas, where efficient use of land is a priority, offering homeowners a versatile and profitable way to improve their properties.

Laneway House Build Cost vs. Rental Income
Before proceeding, evaluate construction costs against the potential rental income:
