ANIBAL BUILDING, RIO DE JANEIRO

palisade creates a narrow screen in front of the discrete, small glazed entrance to a small lobby. To the left of the entrance a large up-sliding electric door, made from perforated aluminium to allow light to penetrate, which provides access to the internal parking.


Fabrication


The 10.7 metre by 11.5 metre metalwork lattice was the most complicated element to design and execute and the team worked closely with Sao Paulo-based metal fabrica- tion specialists Tecnosystem to create it. “While it’s a bespoke design, it’s made from off-the-shelf, commercially available 4 metre-long, 5 mm- thick and 15 cm-wide aluminium strips with round perforations,” says Abreu. “Tecnosystem customises the strips with precision-cut slots for accurate onsite assembly, enabling them to be fitted and bolted together at the required angles using tiny, almost invisible, brackets. “Technosystem installed the structure – attaching it to the building with support pegs deep-set into the projecting side walls and shaped floor beams in a fairly tricky, six-week assembly programme involving scaffolding. It was a difficult process to get right. “All strips are electrolytically painted


white, using a highly weather-resistant product. The white helps define the diamond pattern of the aluminium and provides strong colour and textural contrast with the dark aluminium panels and wood elsewhere. All materials are salt-resistant as the ocean is just a couple of blocks away.”

Anibal’s roof terrace features a small gravelled garden in front of pleasant

seating and eating area for tenants, complete with simple outdoor kitchen facilities.


Overlooking the front of the building, it is bordered by a combination of low concrete walls clad in granite and tall cumaru fencing with the same granite tiling on the floor.


Abreu continues: “While the building is 90 per cent LED lit, the roof has no photo- voltaic panels as it is too small to make it viable to install them.


“This gave us the opportunity to create the roof terrace, a pleasant exterior space for rest and relaxation or casual meetings. To maximise its usability we included an electronically controlled canvas sliding roof to provide shower protection and shade when needed.


“The building is mechanically heated, cooled and ventilated, so we placed the plant and skylights out of sight beyond the roof terrace perimeter, within open-topped, concrete partitions. Integral rooftop gutters drain any rainfall away through internal, concealed downpipes.”


The concrete slab that forms the roof is covered with single-ply membrane and insulating styrofoam, apart from the garden’s gravelled area. On other levels the main interior flooring is made from reclaimed hardwood. Concluding, Abreu comments: “We are pleased with the aesthetics and functionality we have achieved for the Anibal Building envelope, particularly given the constraints we faced,
