With 2020 just around the corner, leading platform for home renovation and design Houzz has shared its top home design trend predictions.

The rise of curves and arches

Curves and arches will emerge as an interior design trend in big ways next year, adding a feminine touch and create softness in spaces otherwise filled with hard surfaces.

Architectural elements of the home will embrace rounded edges through circular windows, arches and curved walls as advances to technology allows architects to challenge structural boundaries.

Cheeky extras

Got an extra 1.5 metres space at the end of your kitchen renovation floor plan? Houzz reports that it's starting to see homeowners no longer decide between a pantry or more bench space if they have spare meterage.

Instead, they are extending into the space, building in integrated study nooks, kitchenettes and banquettes. This trend began at the start of 2019, with study nooks searched on Houzz 26 per cent more than the previous year.

The reign of terrazzo

Increasing 28 per cent in Houzz searches in 2019, the emergence of terrazzo will turn into a full-blown royal reign in 2020.

Terrazzo, a composite material that can be poured in situ or pre-case and formed of chips of marble, quartz, granite or glass, has mostly been seen in bathroom splashbacks but in the new year, we can expect to see it used in benchtops and homewares, with the chips becoming larger and colourways becoming bolder.

Popularity of metal cladding

With an increasing focus on technological innovation, the desire for greater sustainability, the need for safety and always-changing realisations about wellbeing in the home, one of the biggest trends on Houzz is metal cladding.

With recent issues with combustible materials, Houzz is seeing professionals readjust to these new demands - goodbye rendered brickwork and timber slats, hello copper, zinc and steel.

The 'unkitchen' kitchen

As the most popular room to renovate, Australian kitchen will continue to evolve, with contemporary kitchens beginning to integrate small touches of furniture-like elements that reflect the rest of a home's more personalised decor.

At the extreme end, we will see kitchens that disappear completely into bespoke cabinetry, so all their functionality is hidden away when not in use.

The colour trends

Beige, stone, soft eucalypt greens and earthy browns will be strong interior colours in 2020, following their popularity this year. They're hues found in natural materials such as sisal, jute, hem; the colours of unbleached, undyed wool, natural clay colours, natural stone.

However, there is some solace for those who love colour. Houzz's colour professionals predict that strong colours with added shading will be on trend, such as merlot, peacock blue and spicy pink.

Homewares made of biomaterials

The common concern about climate change, sustainability, the harm of single-use plastic and environmental pollution will push professionals to innovate even more in the years ahead, developing new recycled and recyclable materials for homewares and decor.

The 2019 Houzz & Home Australia study found integrating "green" materials was a high priority for 22 per cent of renovating homeowners, a three per cent increase from 2016.

The primacy of wellbeing and biophilic design

Lamps that adjust their intensity according to natural circadian rhythms, decor that seriously integrates plants, soothing palettes, low-VOC paints and architecture designed for wellness will all grow in importance and as a design conversation in 2020.

This trend has already begun to surface, as designers and homeowners introduce natural light from windows and skylights; exterior views and access to nature; and using water sources as fountains, ponds and water features, that can be seen, heard and touched.
