This customer deployed a two-storey granny flat kit on their forested property — modular panels assembled on-site with an upper-level bedroom, ground-floor living, and a covered verandah with fairy lights. All within the footprint of a standard single-storey dwelling.
The owner wanted extra accommodation on their forested property — enough space for a family or paying guests — without permanently altering the landscape. A single-storey build wouldn't deliver the floor area needed within the compact site footprint.
A two-storey expandable granny flat kit — shipped as modular panels and assembled on-site. The upper level adds a full bedroom and balcony, while the ground floor houses kitchen, bathroom, and living space. All connected by an external metal staircase.
A fully liveable two-level dwelling nestled among the pines. Fully fitted kit from A$28,500 — a fraction of traditional two-storey builds. The owner added fairy lights and climbing flowers to the verandah and now hosts paying guests year-round.
These specifications are based on standard two-storey expandable cabin kits. Final pricing depends on delivery distance, site prep, and configuration choices.

A 2 storey granny flat kit is a factory-built, flat-packed modular dwelling that ships to your site for rapid assembly. It includes two full levels — typically ground-floor living and upper-level sleeping — in a compact footprint, connected by an external or internal staircase.
Fully fitted expandable granny flat kits start from A$28,500. Two-storey configurations may be higher depending on size, inclusions, and customisation. Total project costs including delivery, site prep, and utility connections vary by location.
Two-storey secondary dwellings generally require development approval in most Australian states. Requirements vary by council — some rural zones have more flexible pathways. Always confirm with your local council before committing.
Assembly of a two-storey modular kit typically takes 3–5 days on a prepared site with a small crane and crew. Site preparation (levelling, pier blocks) usually adds 1–2 days before delivery.
Yes. Two-storey granny flats are popular for short-term rental (Airbnb, Stayz) due to the extra floor area, privacy between levels, and premium guest experience. Check your local short-term rental regulations.
A two-storey design doubles your floor area without increasing the building footprint — ideal for compact sites. It also provides better separation between living and sleeping areas and often commands higher rental yields.
