3. Palm escape

A mix of warm and cool tones, this interior is full of Wyethian charm and characteristic detail. This look would especially fit well with the pecky cypress ceiling and beams.

A corner summer house (like this A-shaped one!) doesn’t take up too much space. It’s a perfect choice of garden building for hosting parties with family and friends in style.

The majority of summer houses do not require planning permission. But a permission is required for any summer houses which cover over half the garden. Or it's not for domestic use, and it's over 3 metres high with a pent roof or 4 metres high with an apex roof.

A garden summer house can be used as your very own special space. Use it as a studio for writing, painting or other crafting activities. Or it can simply become a space for relaxation and leisure with your loved ones.

Think of anything functional items like furniture, lighting fixtures, plants, and shelving units. Or think outside the box, such as installing a hammock or a fireplace made from reclaimed bricks.

A summer house can also be used in various ways, while a shed is most often used as a storage space. If you only need a place to store your tools and outdoor furniture, then a shed may be the best option.

A carpet can be a factor in adding comfort to your summer house. You may choose between a based floor one or lay down rugs over wood.


Alternatively, you could keep a few rugs in your home and roll them out in the summerhouse when not in use.

The colour of your summer house depends on your taste. But the classic paint scheme is to have the walls in a darker shade, while the doors and windows in a lighter shade.


White, cream or a paler shade of the wall colour works best. Greens, greys, and beige shades also work well with this format.
