A larger single-storey dwelling for family, flexibility, and room to grow.

Meet the Longhouse

The Longhouse is Sprout’s larger single-storey dwelling, designed for people who need more space without losing the simplicity of a repeatable, efficient building system.

Starting from a three-bedroom, two-bathroom layout, the Longhouse can be adapted for family living, multi-generational households, work-from-home space, guest rooms, or cottage life. Its long, open plan creates strong connections between kitchen, living, bedrooms, and the outdoors, while keeping everything on one accessible level.

With durable materials, energy-conscious construction, and a simpler path from permits to keys, the Longhouse offers more room to settle in, stretch out, and grow.

Why it works

Room for real life: A generous single-storey layout with space for bedrooms, shared living, storage, work, guests, and family routines.

Flexible by design: Add a bedroom, adjust an entry, mirror the layout, or rethink shared spaces while staying within the Sprout design system.

Connected to the outdoors: The elongated footprint creates natural opportunities for light, views, patios, sliders, and indoor-outdoor living.

Flexible by nature

The Longhouse is built on a flexible design platform. Start with the base three-bedroom, two-bathroom layout, then adapt the plan to suit your property and the way you live. Common variations include an added bedroom, office, gym, vestibule entrance, alternate side door, mirrored layout, adjusted bathroom location, or additional slider to connect with a deck, garden, or view.
