The Barra Public Transport Inter-change (Barra PTI) is adjacent to the São Tiago fort and the A Ma temple, the latter a major tourist attraction located along the old waterfront. It is an underground station and parking facility for public tourist coach and private cars. The intervention area is 35,957 m² and it extends from the Sai Van Lake corner in front of the S.Tiago Fortress to the D. Carlos dockyard. The building is formed by three basements floors and two over ground floors organized in a double deck public space. The 2 underground levels of public bus terminus are at grade with LRT Station 12 platforms. The Barra PTI project is articulated with the LRT Station to optimize the transfer between Train, Bus, Taxis and private car, and provide an easy, seamless experience of the Ma Kok and inner Harbour Historical District.
Looking at the context of the site and the new transportation role it had to play, our initial agenda became focused on reconciling both districts at the east and west of the site into a walkable interface to deal both with the scale of the heritage district of Barra as well as the new scale of the train and PTI infrastructures. The Barra site turned into one of the main areas of the peninsula where traffic infrastructure is concentrated after becoming home to the arrival of the main deck of the Sai Van Bridge, a public transport interchange and a LRT interchange station located in Macau, in the Barra district.
Our focus centred on advocating for the different agendas that would allow the emptying- up of the core of the site and creating an outreaching pedestrian network. By sinking the bus terminus and shifting the ventilation infrastructure to the side, we allowed the project to build around an urban void and design the roof so that it could incrementally unfold to lay out a rooftop park connecting all the public buildings planned for the district, including a border crossing building to mainland China, the Maritime Museum, and Station 12. This allowed people to walk across the district, from the old waterfronts of the lakes to the new waterfront park and across to the old inner harbour waterfront without having to interface with the traffic flow. The green roof of the PTI creates an elevated public space, with the concept of a suspended natural landscape, and offering a commercial zone with many services, inviting to leisure.
Before, the site was a geographical gap, a discontinuity between the old Chinese city on the west, and the extension of the Portuguese settlement along the Praia Grande to the East. The potential of the project resides in bridging these two historic urban districts and devising new typologies for making them walkable, and part of a continuous visual experience.
