Garden room ideas: paint colours for indoor-outdoor living

Whether it’s a garden room used for entertaining, a kitchen opening onto the terrace or a quiet retreat surrounded by greenery, spaces that connect the home to the outdoors offer wonderful opportunities to decorate with colour.

Choosing paint colours that complement the garden can help create a natural transition between inside and out, particularly when paired with timber, stone and other natural materials.

From leafy greens to fresh whites, here are some of our favourite garden room ideas and colour schemes for bringing the outdoors in.

1. Decorate with green to connect your garden room to nature

Green is a natural choice for garden rooms, complementing the surrounding planting and helping a space feel connected to the landscape.

For a more striking scheme, consider Invisible Green, a vibrant grass green with a rich historical character.

Interior designer Sarah Vanrenen of Vanrenen Hanbury has used Invisible Green in her outdoor garden room, creating an inviting entertaining space that feels like a continuation of the lawns beyond.

Rather than competing with the greenery outside, the colour creates a strong visual connection between the building and its surroundings.

2. Use natural colour to bring the outdoors into your kitchen

You don’t need a separate garden room to create a connection with the outdoors.

Kitchens that open onto a garden or terrace are particularly well suited to colours inspired by nature, helping to create a sense of continuity between the two spaces.

Interior designer Carlos Garcia demonstrates this beautifully in his countryside kitchen, where Olympian Green complements the surrounding landscape.

Paired with natural materials and views of the garden, the colour helps bring the character of the outdoors into the room.

Consider carrying a similar colour through adjoining spaces or onto painted woodwork to create a cohesive scheme.

3. Choose white paint for a fresh, traditional look

White can be a beautiful choice for garden rooms, particularly when paired with timber, natural stone and plenty of greenery.

A soft white provides a gentle contrast to the garden without feeling too stark, while painted window frames and doors can help define the architecture.

Consider warmer whites such as Spanish White or Milk White for an inviting interior.

For garden rooms with extensive glazing, remember that the appearance of white paint can change considerably throughout the day. Testing samples in different lighting conditions will help you find the right shade.

4. Make the most of natural materials and changing light

The most successful indoor-outdoor spaces often have a strong connection to their surroundings.

Timber panelling, natural flooring, woven textiles and painted joinery can all help create a relaxed transition between the house and garden.

Colour is particularly important in rooms with large windows or glazed doors, where daylight can change significantly throughout the day.

Our natural paints are made using real earth and mineral pigments, creating colours that work beautifully alongside natural materials.

When choosing a finish, consider how the space will be used and whether it is fully enclosed, heated and protected from the weather. A garden room used as an interior living space may have different requirements from exposed exterior woodwork.

5. Create a peaceful retreat surrounded by nature

Garden rooms can also offer somewhere to escape the everyday, whether for reading, working or simply enjoying the changing seasons.

Tucked among the trees in Herefordshire, The Quist is a beautiful example of how architecture and interiors can sit comfortably within a natural setting.

Surrounded by woodland and dappled light, this carefully designed treehouse creates a sense of retreat while maintaining a close connection to the landscape.

Choosing the right paint colours for your garden room

When selecting colours for a garden room or indoor-outdoor space, consider the views, natural light and materials already present.

Greens can help connect a room to surrounding planting, while soft whites and earthy neutrals offer a versatile backdrop for timber, stone and garden furniture.

If you’re decorating a space that opens directly onto the garden, consider how the colours will look both with the doors open and during the darker winter months.
