Main Façade Technology
Paddington Square

The slightly ventilated cavity has a bespoke gasket designed to ensure sufficient natural ventilation of the cavity, while providing seal from external rain and noise. The design was supported by detailed FEM structural models of the façade including computational fluid dynamic (CFD) analysis to ensure the behaviour of the façade within the ambitious thermal performance targets.

Another challenge was posed bye the large cantilevering "wing wall" - at each corner of the building, the external skin of the façade is cantilevering by 1.5m from the slab edge. It consists of a bespoke reinforcing plate inserted within the transoms of the last unit acting as tensioning and compression distribution at top and bottom of the unit. These last unis required a bespoke launching trolley for installation, which we have designed and crafted in an artisal way.

The corner slabs supporting the structure are external, this has required for a bespoke concertina gasket around the penetration and a split unit with prefabricated thermally insulated collar installed from the floor around the steel penetrations.

Our R&D dept. have conceived a bespoke solution to adjust the design of the external shading devices (in cast aluminium) to be suitable for extruded aluminium, thus saving costs without compromising the aesthetic.

SYSTEMS

The glass cladding designed and manufactured by Focchi Group gives the building its sleek look and allows light to pour into even its darkest recesses.

The main façade of Paddington Square is characterised by a compact ventilated double skin system, with bespoke configuration of glass coating and solar measures (perforated venetian blinds and louvres), thus ensuring that the glass doesn't need any heat treatment for shock risks, therefore all glass is annealed. This system consists of a double skin façade featuring a castellated mullion with the external fins acting as structural elements for the façade.

This 17-storey mixed use building is designed to float above the ground floor. Facades under the building are set back to maximize the public realm.

When standing in the Piazza in front of the station, you look up and see a square screen of over 50 by 50 meters, expressing the geometry of the cube.
This screen is the double skin facade of the office building to protect the solar screening venetian blinds. This system makes the building highly efficient to both save energy and provide natural daylight to penetrate deep into the office floors.

The building is a cubic volume which provides prime quality working spaces for over of 4000 people and brings valuable employment opportunities to the Paddington area.
Panoramic lifts take the public up to level 17 offering a large terrace and a restaurant providing magnificent 270° views including Hyde Park, the City and virtually all of Westminster.

A large new piazza places the pedestrian experience at heart of the scheme and create an iconic address for the new office building, overlooking the public realm.
