东方绿色校园丨葡萄牙里斯本丨KPF,Saraiva+Associados

Architecture studios KPF and Saraiva+Associados have completed the Oriente Green Campus in Portugal, transforming the structure of an abandoned shopping mall into a block of workspaces punctuated by green terraces and courtyards.

Located in Moscavide to the north of Lisbon, the project adapted an unfinished, city-block-sized structure that was originally planned as a shopping mall before construction stalled in 2012.

As part of the regeneration of the Parque das Nações district into a technology hub, global studio KPF worked with local firm Saraiva+Associados (S+A) to transform the abandoned site into 42,000-square-metres of workspace and a campus for the European University.

This involved breaking down what KPF principal John Bushell described as the "hulk" of the mall's structure, using its wide floor plates to create a series of stepped terraces that overlook planted courtyards and rooftop terraces.

It was built within the structure of a half completed mall

"The overall intention was to bring new life to an unfinished shopping mall and transform it into a knowledge economy hub – it's the ultimate reuse of embodied carbon to create an exciting new place," Bushell told Dezeen.

"The huge, simplified layout of the mall was diametrically opposite to the dense network of streets making up the adjacent neighbourhood, and so we sought to humanise the scale of the building."

"Internally , we created a network of connected spaces, and externally there are multiple entrances and modulations in elevational treatment, so the former hulk becomes a granular extension to the historic pattern of complexity and variety," he added.

The roof and multiple terraces are covered in gardens

The deep floor plates designed for the mall were repurposed as a series of flexible office and teaching spaces. Minimal interiors see the coffered concrete floor plates retained for office levels, and timber linings introduced for communal areas such as a cafe and auditorium.

A total of nine external spaces occupy the heart of Oriente Green Campus, featuring a mix of public events spaces, courtyards and private office terraces that were designed by landscape studio JL Group.

The internal squares include timber canopies

Stepped levels around the centre overlook deeper, squares below shaded by timber canopies, with the external areas linked by winding paths between curved planters and spiral staircases in white-painted steel that wrap glass lift shafts.

As well as creating a variety of spatial conditions, these external areas allow for the independent ventilation of the surrounding workspaces via openable windows.

"There is a huge fifth elevation of horizontal surfaces in the courtyards and roofscape which become a lush, multiple level, garden landscape," Bushell told Dezeen.

"Simple steel staircases link every level within the central courtyards, and are part of an organic Modernism, with white surfaces enjoying the play of shadow and light that changes throughout the day," he added.

The building contains flexible office and teaching spaces

On the roof of the block, a skinny, pavilion-like office space has been added, topped by an undulating timber roof and lined by glazed walls offering views both of the rooftop terraces and across Lisbon.

Externally, the block was clad using local terracotta tiles glazed a glossy white, which also line the soffits of deep, planted balconies created around the perimeter.

Other recent projects by KPF include a waste incineration plant in Taiwan, with a spiralling form clad in perforated aluminium screens that hugs a landscaped terrace. The photography is by Fernando Guerra.
