4 Bedrooms | 3 Bathrooms | Double Garage | 2 Storeys | 321.6 m² (3,459 sq ft)

A Spacious Family Home Designed for Narrow Blocks

Building on a narrow block doesn't mean compromising on living space.

The 321 KEEN Modern 4 Bedroom House Plan offers a contemporary two-storey home with generous family accommodation, multiple living areas and practical indoor-outdoor entertaining spaces.

Designed around an elongated floor plan, this home provides four bedrooms, three bathrooms, a double garage, two balconies and a covered alfresco area.

With separate living spaces across both levels, the design is ideal for growing families who want flexibility, privacy and room to entertain.

Our affordable downloadable concept plans allow you to explore this design, discuss possible modifications and obtain preliminary building quotations before investing in detailed construction documentation.

Ground Floor – Open Living and Entertaining

The lower level features an open arrangement of family living spaces, with a centrally positioned kitchen connecting the dining, family and lounge areas.

The kitchen includes an island bench and walk-in pantry, creating a practical layout for everyday cooking and entertaining.

A separate rumpus area offers additional recreational space, while the covered alfresco patio extends the living area outdoors.

The ground floor also includes a double garage, entrance porch, powder room, laundry and internal staircase.

Upper Floor – Four Bedrooms and Family Retreat

The upper level provides private bedroom accommodation alongside an additional living area.

The master bedroom features an ensuite, walk-in robe and access to a balcony.

Three further bedrooms are positioned near the main bathroom.

A spacious upstairs rumpus room offers flexibility for a television area, children's retreat or additional family living space.

The dedicated study nook is conveniently positioned near the staircase, providing a useful workspace.

A second balcony creates another outdoor relaxation area.
