Attic storage can be accessed via a pull-down ladder or stairs, while basement storage can be accessed through a door or bulkhead. Duplex house layout plans should consider the potential for attic and basement storage and incorporate access points and lighting into the design.

By carefully considering these storage needs, architects and builders can create duplex house layout plans that provide ample and functional storage space for both units, ensuring that occupants have a place for everything and everything has a place.

Outdoor space

Outdoor space is a valuable asset for any home, and duplex house layout plans should carefully consider the incorporation of outdoor living areas. Here are some key points and details to remember when planning for outdoor space in a duplex house:

Patios and decks: Patios and decks are popular outdoor living spaces that provide a place to relax, entertain guests, and enjoy the outdoors. Duplex house layout plans can incorporate patios or decks off the living room or kitchen area, creating a seamless transition between indoor and outdoor living. Patios can be constructed of concrete, pavers, or other durable materials, while decks are typically made of wood or composite materials.

Yards and gardens: Yards and gardens offer more extensive outdoor space for activities such as gardening, playing, and entertaining. Duplex house layout plans can include private yards for each unit, or a shared yard that is accessible to both units. Yards can be landscaped with grass, trees, shrubs, and flowers to create a beautiful and inviting outdoor space.

Balconies: Balconies are elevated outdoor spaces that can be incorporated into duplex house layout plans to provide additional outdoor living space, especially in urban areas where land is limited. Balconies can be accessed from bedrooms or living rooms, and can offer views of the surrounding area. They can be constructed of wood, metal, or concrete, and can be designed with railings or screens for safety and privacy.

Common outdoor areas: In addition to private outdoor spaces for each unit, duplex house layout plans can also include common outdoor areas that are shared by both units. These areas can include a pool, barbecue area, or fire pit, and can provide a space for socializing and community building among the occupants.

By carefully considering these outdoor space needs, architects and builders can create duplex house layout plans that provide functional and inviting outdoor living areas for both units, enhancing the overall livability and enjoyment of the home.
