LG Smart Garden

LG Smart Garden

This garden is, primarily, a relaxing place to be.  In harmony with this, we have sought to incorporate technology to showcase how the ever-evolving connected world can even assist with our enjoyment of the most natural of gardens.

Our designer, Hay Joung Hwang has pushed the limits to design something really special and a little unusual for Chelsea this year.  The most striking of these is the 5.5m long cantilevered pergola which offers such a versatile and interesting way of adding height and texture to the garden.

Visually, Hay wanted to employ a very natural and light style with a strong romantic look throughout.  This garden focuses on a blend of Scandinavian ‘cool’ and zen oriental tranquility, with pale tones of blues and pinks to soften the contrast and make the whole experience more subtle and spacious.

Completing the picture of relaxation and tranquility is the beautifully-crafted wooden water wall, which adds levity and movement to the garden as the water cascades and the light dances from it.


Plant List

The planting scheme in the garden is designed to combine romantic pastel shades of iris and poppy in a cottage-garden style to offer a feminine, naturalistic counterpoint to the modern canopy structures.

Texturally, ferns and other foliage plants form a bed to support the soft, ethereal planting of Stipa and Briza which, in turn, are punctuated by vertical accents of Digitalis and Eremurus.

Garden Features

What is a Smart Garden?

The LG Smart Garden is a garden which is supported by the principles and technology of home automation.

Widely applied in the interiors of homes, the technology is slowly finding its way outside.  Hay’s desire in creating the Smart Garden was to create an experience which was both visually appealling and, underneath it all, connected.

How does it work?

Electricity for each of the lighting, irrigation and water feature circuits stems from a central location.  At that location, our electricians have installed a bank of sockets into which we have placed Wemo Insight switches with the plugs from our various circuits inside them.

Those switches communicate with our LG G5 mobile handsets over a standard wi-fi network so that they can be controlled from anywhere in the world.

Can I do this at home?

Absolutely.  Wemo is easy to use and widely available both online and in retail stores.  Simply plug them in to any outlet, plug in your devides and connect.

All you need to remember is that they are not for external use; your electrical circuits need to come back into the house, garage or IP-rated shed, to be plugged in.  The switches need to be within range of a wi-fi router, and you need a smartphone running Android or iOS.

Tell us about your Water Wall

Perfectly complementing the garden’s focus on technology, Accoya has been used to create a centrepiece with a twist.

A specially-constructed Accoya-made panel has been used to form a stunning water wall, demonstrating the stability and durability of the product even in the wettest of conditions.

The bespoke water wall was fabricated off site and assembled at the workshops of Alan Hayward Joinery, before being shipped to aquatecture specialist Andrew Ewing, who designed and specified the pumps, chambers, flow systems and supervised its installation on site.

Previous Show Experience

Chaumont sur Loire (2014)

Seoul Garden Festival (2015)

This is, indeed, my first show garden at Chelsea.  I have done a number of show gardens in the past (Chaumont sur Loire, France (2014), Seoul Garden Festival, Korea (2015), where I was invited by the Mayor of Seoul to create a garden), but not on the scale or to the standard of Chelsea.
I have been working as a Project Landscape Architect at Randle Siddeley for almost six years, so am used to designing beautiful gardens for very wealthy clients (many of which, sadly, are never seen by the public), so this was an amazing opportunity to build something which everyone can enjoy.

This is, I believe, the first time that LG have sponsored a garden.  They are very excited to be involved with such a prestigious event and this is a nice way to showcase some of their emergent technology in a stylish but informal surrounding.  The emphasis is very much on the garden, but there will be a couple of ‘toys’ for modern living which give an insight into how we might be using (and caring for) our gardens in the future.  LG has a long-standing interest and investment in arts and culture, including various global collaborations across fashion, design, music and art and they seemed like an excellent fit for my garden.

I trained originally as an interior designer and, as well as being a landscape architect and garden designer, am a bit of a techno-lover.  I have always enjoyed the idea that as inhabiters of a space we can interact with our homes and gain so much more than just shelter and warmth from them.  My garden concept is an extension of this and the technology is really only just starting to become available. 

My work and the creative direction of my landscape design practice, Hay.Design Ltd, is centred around combining traditionalism and modernism. My recent project at the Seoul Garden Festival, Dayoun, was inspired by the traditional Korean ritual of tea drinking, but created a very modern space of calm and meditation for the mind.
It was this garden, in particular, that resonated with LG, a brand that is itself rooted in Korean culture and yet reaches a very modern global audience by being at the very cutting edge of technology innovation.
LG’s Smart Garden at the RHS Chelsea Flower Show again echoes this meeting of traditionalism and modernism and therefore reflects both Hay.Design Ltd’s design ethos and LG Electronics brand essence.
