Appreciation towards Like Architects for providing the following description:

这是一个临时安置在里斯本广场上的圣诞装置—-“冰树”，可以在夜晚发出光亮，并影响和改变广场上行人的 路径。广场因为这片树林，有了一个新的景观和环境。材料是具有透光性的聚丙烯塑料，并被加工出许多孔 洞，在白天和夜晚，这些冰树们，都演奏出让人惊讶的阴影和景观。内部的光源是LED灯，白色的光芒创造 出一个有趣的圣诞氛围。

这些临时装饰可以快速的生产和安装，撤销也非常容易，不会对城市环境造成影响。LED光源非常节能。所 用的主材聚丙烯塑料具备很高的重复利用率和回收性。这些冰树在圣诞结束后，在其它地方和空间，得到了 运用的机会。

“FROZEN TREES” is a temporary installation for Christmas lighting in D. Pedro IV square in Lisbon. It builds an illuminated, frozen and fractal Christmas landscape that affects and alters the path of passers by. Thirty cylinders – structured, self-sufficient streetlights – are placed throughout the square, drawing a new landscape and context and inviting the visitors to new spatial experiences.

Designed from the creative association of ”Rationell Variera” piece by K Hagberg/M Hagberg (IKEA – 1,5€), and taking advantage from its shape, “FROZEN TREES” brings a domestic object to the scale of the town – thus dissociating it from its original function and leading to the loss of its identity as a single element, making a general call for creativity in the current socio-economic conjecture.

The volumes, made of multiple holes, are visually trespassed and define an ethereal presence in the square. The installation takes then advantage from the holes of the original object and the translucent properties of its material – polypropylene plastic -, simultaneously flexible, non-inflammable and highly absorbent and potentiating the transmittance of light, either natural or artificial. Blending with the urban surrounding, “FROZEN TREES” presents different characteristics during the day and night: by day, the trees make surprising shadows and the ensemble makes an abstract, white and tracery landscape,

through which we see the surrounding; by night, illuminated from inside by LEDs, the elements, as street lamps, explode with white light, creating a Christmas ambience with variable intensity.

Structural and constructive strategy

A 160 x 450 mm plastic piece is the basic element for the modular logic of this project; in fact, it is the size of the element that draws the structural module.

Each of the 30 trees is the same height – 3,6 metres – but three different diameters coexist – 5, 10 or 15 pieces in the bottom – totalling ten units on each of the three sizes.

The light metal structure is made of vertical profiles and horizontal triangular rings; the first receive the IKEA pieces, the latter the illumination network made of monochromatic LEDs.

Twenty four hundred ‘Rationell Variera’ pieces were previously fastened to the structures, still at the studio, and later transported to the Rossio. Once at the destination, the basis of these elements was fixed to the ground, to ensure its stability.

Sustainability strategy

“FROZEN TREES” is a fast production and easy set-up installation, able to pop-up and disappear from a city without destroying or damaging anything.

“FROZEN TREES” illumination is based upon a white monochromatic LED system, characterized by low voltage and energy consumption and also able to adjust the light’s intensity. Each element’s energy supply is made by a car battery that ensures its autonomy throughout the Christmas period.

Regarding the effect/cost ratio, choosing a standard object proved to be an effective solution, allowing for a unique aesthetic result for a very competitive price. On the other hand, polypropylene plastic pieces are reusable and highly recyclable.

Now, with the Christmas period to end, “FROZEN TREES” are looking to other places and squares of the country, so they can adapt, in a surprising and innovative way, to new contexts, suggesting new spatial opportunities.
