A double storey extension can be a brilliant way to add meaningful space to your home. Unlike a single storey extension, it can improve both the ground floor and first floor, making it ideal for homeowners who need more living space as well as extra bedrooms or bathrooms.

In Sussex, double storey extensions can work beautifully when they are carefully designed around the existing property, neighbouring homes and local planning considerations.

Planning Considerations

Double storey extensions often require more careful planning than smaller extensions because they have a bigger impact on the appearance of the home and surrounding properties.

Planning officers may consider the size, height, roof design, overlooking, loss of light and how the extension relates to neighbouring homes.

A strong design should feel balanced and proportionate.

Neighbour Impact

Because double storey extensions are taller, they can affect neighbouring properties more than single storey designs.

Overlooking, privacy, overshadowing and boundary positions all need to be considered early. A well-designed extension should improve your home while remaining sensitive to the surrounding area.

Roof Design

The roof is one of the most important parts of a double storey extension. Matching the existing roof can help the extension feel seamless, while a more contemporary design may create a deliberate contrast.

The roof design will also affect the internal layout, insulation, drainage and final appearance of the property.

Layout and Flow

A double storey extension should improve the whole home, not just add rooms.

On the ground floor, it may create a larger kitchen, dining area, utility or living space. Upstairs, it may allow for an additional bedroom, en-suite, dressing room or improved family bathroom.

The best designs make the new and existing spaces flow naturally together.

Structure and Cost

Double storey extensions usually involve more structural work, more scaffolding, more roofing and more internal finishes than single storey extensions. However, they can offer strong value because the same foundations and roof can support two levels of additional space.

Final Thoughts

Double storey extensions in Sussex can add space, value and flexibility when designed and built properly. With the right planning, craftsmanship and attention to detail, they can transform both the appearance and practicality of your home.
