From the architect. Kew Garden’s Tree Top Walkway opened on 24th May 2008, Kew’s Year of the Tree, to over 9,000 visitors. The Walkway is a thrilling experience, taking visitors 18m high into the tree canopies for a birds-eye view of Kew, providing insights into the special role of trees in our breathing planet and the intimate views of a deciduous woodland and its inhabitants from within the tranquillity of the leaves. Inspiration for the walkway was drawn from the ancient Fibonacci sequence found repeatedly in nature.
In conjunction with the Walkway, an underground ‘Rhizotron’ exhibition space is attached and which explores various themes associated with tree root biology, climate change and the relationship between tree roots and microorganisms. Its appearance is inspired by a natural cracking within the earth to reveal a dark and dynamic space rich with exciting and educational content.
Marks Barfield Architects designed the walkway to be a visually light, discreet presence, at ease in its natural surroundings; while at the same time being unashamedly man-made. They decided to integrate the structure with the handrail support and drew on the Fibonacci sequence, which underlies many growth patterns in nature. By using the progressive series of numbers associated with the sequence (1,1,2,3,5,8,13,21,34, etc), we were able to work to create a ‘Fibonacci grid’ along a typical walkway truss, resulting in a higher density of elements near the trussends where the vertical loads are highest.
A major challenge was to strike a balance between enabling visitors to get as close as possible to the tree canopies and being mindful of the complex tree root system below ground. A radar survey was undertaken to understand the extent of tree root activity at the proposed pylon and pile foundation locations. This enabled strategic positioning of the 12-18m long concrete piles between the major roots ensuring safety and longevity for the tress and walkway.

Divisual have designed the Planet-O Lamp, made from metal discs welded by hand.
Description
Planet-o is composed by about 250 disks of metal expertly welded by hand, through a process of brazing brass.
Planet-o is a body that enlightens it self and illuminates the ‘environment through the interplay of light and shadow.
Its main feature is that every lamp, coming by the expert hand of the workman and not through a digital model may not be reproducible. This peculiarity makes each product unique.
Design: Divisual

There’s a nostalgia associated with model trains and railroading — even if it’s unspoken. Railroads take us back to an earlier era. A more basic time. When spending a week or more on a train was seen as a luxury — an event in itself — not at as merely a mode of transportation.
You’ve probably already scouted some model railroad shows. You’ve no doubt recognized the camaraderie and the passion these folks have. And yes, you’re interested in becoming a part of that.
“The Wonderful World of Model Trains” will help you do just that! It’s a comprehensive guide to model railroading written for someone who is new to this hobby, starting with some basic “train knowledge” & terminologies, and continuing on to the more detailed aspects of the hobby.
And yes, this hobby can indeed get quite detailed. And that tends to be intimidating to some people. The beauty of this hobby is that you can get involved at just the level you care too. You’ll discover that every model railroader is in it for the love of the trains and the history. The vast majority of us are not out to make a fast buck from our interests.
Here’s some of the things you’ll learn in “The Wonderful World of Model Trains”:
– How to create stunning terrain in your scenery with these 3 simple techniques…
– Different scales, gauges, standards in the world of model railroading and what they all mean…
– 2 simple keys (that are right in front of your eyes) to build your own benchwork…
– WARNING: 3 things you should never do when it comes to wiring…
– A pennies on the dollar approach to finding model train parts…
– How to avoid derailing problems…
– 3 proven steps to running multiple trains on one track…
– 6 time tested and proven strategies for laying out train tracks…
– When to add onto your set with locomotives and rolling stock…
– 7 everyday but often overlooked tips and tricks for building the best layouts for your scenery…
– How to do general maintenance on your model trains and tracks…
– And much more…
