Whilst you won’t find modern furnishings and materials in this décor trend, contemporary rustic styles combine elements of the old and new for a fresh, light and grounded aesthetic – a trend that’s also on the rise.

To successfully replicate this interior trend in your own home, opt for a muted pastel colour scheme, accompanied by vintage style prints like floral or check. Consider enhancing the space with natural elements like plants and flowers, as well as vintage vases and crockery.

To replicate elements of this décor trend in your home, the key is to use wooden textures, whether it be through floorboards or wall cladding, to shelving or a bath rack.

When it comes to home office design schemes, the possibilities are endless, which can be seen through more than half a million hashtags on Instagram! Thanks to the coronavirus pandemic the majority of the workforce is working from home, so there are plenty of home office décor inspiration to be found on the app.

When decorating your home office, it’s important to create a space that is comfortable and keeps you motivated. For some, this may be through incorporating pops of colour though accent walls, bright accessories or colourful storage solutions. On the other hand, others may prefer a simple, minimalist vibe, with white walls, plants, and cork accessories instead.

Dating back the late 1900s, postmodern design embraces unconventional ideas with an emphasis on playful, artsy and extravagant style.

To successfully nail this décor trend in your home, pair vibrant furniture with contrasting shades, creating a mishmash of colours, patterns and textures. Postmodern design incorporates various shapes too, so be sure to add these into your space through art, sculptures, or cushions.

Incorporating stone elements into your interior is easy. From Italian marble, durable granite to rustic slate, each stone has its own unique appeal, and there is something for every home.
