Why open plan works

Almost everyone enjoys having guests over. Weekend lunches and evening gatherings take place in the kitchen and living room. A rear extension transforms a small kitchen into a spacious open-plan area with more convenient storage and more efficient movement. As a rule, the dining table is located between the living room and the kitchen, creating a sense of a single space. This idea is suitable for single-storey houses and townhouses in the suburbs, where additional space means higher property values.
Simple home extension for outdoor connection

A simple extension at the rear of the house can be designed for both indoor and outdoor living. This is easy to achieve by installing wide doors that open directly onto a wooden terrace or paved seating area in the garden. The design connects the interior and exterior spaces with a uniform surface finish, making the space appear larger. The house acquires a natural fluidity without major construction work. The cost remains low if you keep the roof line simple and use lightweight cladding. This rear extension idea is suitable for older houses with board cladding and Californian bungalows in the Melbourne suburbs, where the backyard is the centre of life.
