Blog: Designing a garden to match Interior Colours

Successful garden design blends shapes, colours and materials without jarring the eye. It’s the delicate art of fusing complementary elements to build a story, that in turn evokes a particular experience – whether that’s an energetic rush or a soothing ease – and everything in between.

Creating a seamless transition between your home’s interior and surrounding landscape is a balancing act.  It’s the connecting threads that you don’t always notice that entwine the essentials and the thoughtful use of colour, that brings the complete picture together.

  1.  The first cue should be taken from the architecture and location of the home.

“I begin with open awareness and curiosity, taking note of the building style, location of the property and character of the home owner,” says Pepo Director and Designer, Nicola Cameron. “Transitioning between the spaces from inside to out should be effortless.”

Natural pairings like sandstone and wood call for a different garden treatment to a red brick retro home for example, which sits more happily amidst plants in strong green and primary colours. A house nestled in a dark valley with very little breeze enjoys a visual lift with the help of brighter colours and plants that reflect light, to add vibrance.

By contrast, a timber and glass beach-side property on a wide hot road and perched on a hill, cries out for refreshing, cool surrounds that are calm and grounding.

2. Floor coverings, cushion colours, benchtops and furniture provide valuable colour clues.

Selecting the dominant interior colour will inform supplementary shades and establish a cohesive design. A stainless-steel kitchen bench top with chrome finishes does nothing but sing when a clutch of sheeny, reflective plants sway in the breeze, outside an adjoining window in the garden.

Equally, a piece of art in dominating hues will demand attention as you enter a room and calls out for a brightly flowering tree for example, to support its visual positioning. Home owners and guests alike almost breathe a sigh of relief once the blossoms catch their eye and balance is achieved.

  1. Paint choices are a crucial indicator.

The homeowners of this property in McMahon’s Point, (designed by  Tribe Studio) chose chose a black and white theme which extended to the rear of their house.

The Pepo Botanic Design team had to select the garden colours carefully, to complement the architectural hues and natural tones of the internal furnishings.

A mix of green plants with white flowers (to link the crisp exterior paint colour) were selected including Ophiopogon jaburan, Hydrangea sp, and Gardenia augusta. Meanwhile, the black architectural detailing was anchored by darker foliage choices such as Acer palmatum ‘Bloodwood’, Aeonium schwarzkopf and Ajuga ‘Jungle Beauty’.

White pots were included and soft white sandstone chosen as the ground material which illuminates at night thanks to soft lighting. (For more, visit McMahons Point Garden).

4. The relationship between the different hues on the colour wheel determines the likelihood of cohesion, no matter what the space.

Given the bright light of the harsh Australian sun, it’s important to follow some clear rules. Separating your choices into “hot” and “cool” colours is the starting point. ‘Hot’ tones such as reds, oranges and yellows are adjacent on the colour wheel and their shared yellow pigment, when planted together, creates a feeling of harmony.

Cool colours that sit alongside one another on the wheel share a blue pigment and mingle together most comfortably in the garden to create a calming synchronicity.

And while white is a perennial favourite it needs to be integrated mindfully and is best used as a punctuation point to lighten up a dark corner alongside silvery leaved foliage. “White isn’t a dominant colour in nature and it’s important to consider it carefully when using it as a design element,” says Nicola. “Often it’s best to combine white coloured plants in a garden with a cool pallet rather than hot.”

This contemporary renovation in Bellevue Hill, (illustrated in the Garden Elevation and Material Precedents diagram shown below), was designed to create an open, happy and colourful space.

With three boisterous boys, two Mums and their dog Buddy to accommodate, the garden had to be all about entertainment and fun. Lively colours such as pinks, oranges and greens were used to complement the family’s personalities as well as interior tonal choices and brought to life through a variety of  plant choices, including those shown below.

Ensuring that the internal and external spaces visually and functionally flowed into one another was important to creating a flexible and uplifting space for family and friends.

  1. Finally, fashion and trends will always influence our colour choices.

Autumnal colours are currently trending and are “being used to create cosy, joyful spaces that nurture and inspire,” according to the Dulux Season Trend forecast 2019. (For more, visit Dulux Colour Trends.)

Designed to connect with nature, combinations such as natural deep greens intermingle with authentic neutrals, copper hues and soft terracotta to create a palette which is natural and designed to restore. Soft internal furnishings in burgundy hues for example could be linked with a Japanese maple tree with its coppery hues, just as blue hydrangeas would blend beautifully with sage green interiors.

The level of saturation is also important and there are many variances in the brightness of colours. While the breadth of shades offers greater choice, it can also impact the success of a design and even the slightest nuance in colour needs to be considered.

Our capacity for absorbing what surrounds us is often subtle and we don’t always realise that an easy transition between spaces, can be deeply restorative.

Removing visually jarring elements in our environment, no matter how slight, creates a sense of space and the role of colour will always have an important part to play.

Finally, when trying to determine the ‘go-to colour that never fails’ in the garden, the answer is more straight forward. “While yellow, pinks and reds are popular favourites,” says Nicola, “the colour green with all its tones and textures will always be a clear winner.”
