More space. More possibility.
26 designs from 25 to 60 m² — studios to three bedrooms — designed, approved and built by J&N across Sydney and regional NSW, with design and approvals included in the price.
Built to the same standard as your home
Every J&N granny flat is built on site to suit your block, with a fixed price that covers design, approvals and construction. Progress payments line up with each build stage, so you always know what you’re paying for.
Prices include GST. Site-specific costs are confirmed after your site inspection, never after you sign.

26 floor plans, two finishes
Every design comes in cladding or face brick, with a choice of colours. Select a design to view its full floor plan, room sizes and both elevations.
Indicative plans only, not for construction. Dimensions are approximate external sizes. Listed areas are living space only; garages, porches and decks are extra. Final designs are subject to site conditions and council or certifier approval. Layout changes within 60 m² are available on request.
