The Quiet Mark Treehouse & Garden by John Lewis

the brief

A Quiet Sanctuary


  • Sussex Business Awards – Winner 2014

Sound is increasingly becoming a more important consideration when deciding what technology to buy for our homes. John Lewis’s pioneering partnership with the Quiet Mark award programme sets a new benchmark in sound quality for the next generation of high performance low-noise technology, designed to be in closer harmony with nature. A not-for-profit organisation, ‘Quiet Mark’, is the international mark of approval from the UK’s Noise Abatement Society, endorsed by DEFRA, encouraging the design of quieter high performance technology and solutions to reduce unwanted noise in our environment. The distinctive purple Quiet Mark assures consumers that a product is one of the quietest in its category with an easy labelling system at point of sale.

This whole project was initiated by Poppy Elliot, MD of Quiet Mark. This unique partnership aimed to raise awareness and evolve consumer understanding of sound quality whilst working to develop a new era of sound measurement for electrical products sold at the UK’s favourite department store.

Working collaboratively with Quiet Mark and John Lewis, we designed and built the Quiet Mark Treehouse, an ambitious project erected as the central feature at the renowned RHS Hampton Court Palace Flower Show. The theme for the 2014 event was ‘grow, inspire and escape’ so it was important that the treehouse reflected these concepts. With over 130,000 visitors expected at the show, the treehouse was to sit within a spectacular garden designed by acclaimed garden designer David Domoney of ITV’s Love Your Garden. The structure had to be magical; reflecting an ethereal haven inspired by nature and the great outdoors.

A modern and innovative structure

Designed with elegant curves and shielded from the loud noises of the outside world, the Quiet Mark Treehouse offers the perfect balance between style and tranquility. Modern and innovative, the structure combines state-of-the-art gadgets and appliances, naturally beautiful timber and carefully styled interiors. Its bold contemporary design means that the structure can be installed independently of a host tree, yet still provides you with that wonderful treetop feeling, letting you look down on the world below.

Suspended high above the ground, 26 large laminated timber ribs surround the treehouse – looking just like the trunks of ancient trees clustered together in a copse. Each of the 6m high timber ribs are finished with a unique and sustainable timber product called Kebony, a sustainable alternative to tropical hardwood. Kebony was a fitting choice for the treehouse because of its strength and environmental credibility. At ground level, three primary trunks formed from 48 interlocking ‘Medite Tricoya’ timber fins supported the cocoon-like creation. Besides being weather proof and durable, Medite Tricoya can be easily machined and painted. Each of the fins has been stained dark brown to match the external cladding of the building, reflecting the natural bark of trees.

Inside, the treehouse is quiet and comfortable, finished with a beautiful John Lewis Coir carpet and premium grade Cedar lining to give the building a light, natural and luxurious feel as well as a lovely woody fragrance. Patterned floor-to-ceiling windows act as a decorative feature while giving the room a bright and spacious feeling. Lunch and snacks can be prepared at the contemporary kitchenette and island, meaning that you don’t have to keep making return trips whenever you start to feel peckish.
