Sadly, we can't all move to Hawaii, but the fun doesn't have to end when the holiday's over! Bold print wallpapers can work to provide an oasis of tropical colour right in the middle of dreary Britain; pair with clean and simple furnishings to give the impression of a larger space and remove any blocks to natural light.
A few exotic plants placed around the room can provide a cheap tropical flare to any spot in the house. A beautiful and long flowering burst of floral colour can be produced by an orchid or two, which works to catch and reflect natural light and create a feeling of relaxation in the room. Large and clear fish tanks full of exotic species would fit right in against the bold wallpaper and serve as a focal point, however you should also aim to draw the eyes to the windows and focus on the light! Using tropical scents and air fresheners such as guava or passionfruit can really help to get you in the Hula mood!
To really top it all off you can use music or sounds, tying together multiple senses so that you're seeing Hawaii, smelling Hawaii and hearing Hawaii which works to make you really feel like you're climbing a volcano wearing a giant tiki on your head! Don't forget your tropical drink!
