Inclusions

What's Included

Vaulted living area

A raked ceiling over the living space makes a compact footprint feel taller and more open than a flat-ceiling layout of the same size.

Full-height glazing

Floor-to-ceiling glazing to the living area brings in natural light without needing extra floor area.

One well-proportioned bedroom

Sized for a queen bed and built-in robe, not compromised down to fit the smaller overall footprint.

Energy-efficient build standard

Double-glazed windows and a high energy-efficiency build standard as the base spec.

Who The Hahndorf Suits

This design exists for sites where width is the real constraint — a side-yard block, a narrow inner-Adelaide allotment, or a rear yard that doesn't have room for a wider footprint. At roughly 40-45 sqm, it's smaller than a family-scale two-bedroom layout by design, and the vaulted ceiling and full-height glazing are there specifically to stop that smaller footprint from feeling like a compromise.

It suits a single occupant, a couple, or a use case that doesn't need a second bedroom — a home office, a parent's retreat, or a compact rental. Like every design in the range, it pairs with any theme from the Interior Range. If your block is a standard width and a second bedroom matters, The Stirling is the better starting point instead.

FAQs

Common Questions About This Design

How big is The Hahndorf?

Approximately 40-45 sqm, sized specifically for narrow or side-yard blocks rather than a standard-width site — exact dimensions are confirmed at your design consultation.

How much does The Hahndorf cost?

Indicative pricing for a design at this size and spec generally sits in the $130,000-$160,000 range before site costs — see our cost guide for how site conditions affect the final figure.

Why does it have vaulted ceilings?

A raked ceiling over the living area makes a smaller footprint feel more open, which matters more on a compact design than a larger one.

Is one bedroom enough for a rental?

It depends on your tenant profile — a one-bedroom design suits a single occupant or couple well, while a family-scale rental brief usually suits The Stirling's two-bedroom layout better.
