Deansgate Square

The façade systems, developed to meet the architect and client requirements, include structural silicone glazed units and spandrel units with inward opening purge vents, with a 4mm thick perforated aluminium scenographic balustrade, to a bespoke design. These units include integrated duct systems, which have been bespoke design and tested to achieve the best in and out air exchange, and manual opening through the integrated internal balustrade.

The structural silicone units, 1500mm wide and 2850mm high, consist of Low-E double glazed unit with a “dot matrix” silk printing to minimise solar radiation.

Profiles and decorative balustrades feature a silver or dark grey anodized finish, depending on the elevation.

In order to emphasize the aesthetics, a careful use of different colours between the main elevations of the four towers gives life to ever-changing shading. These tones of grey underline the vertical character of the scheme and create subtle colour changes, accentuated thanks to the star section of the building in plan where each dihedral projects its own colour shade.

A study of the façade system, that paid particular attention to detail, was carried out to allow the achievement of an excellent thermal performance averaged over the entire floor equal to 1.0 W/m2K°, quite a success starting from a single double glazing.

Another innovative challenge overcome was to apply a third-generation Low-E coating capable of mediating between the need for an excellent sunscreen in the summer phase and the potential recovery of solar gains in the winter phase (application on the internal face, # 3) G (solar gain) tot. 58% in clear vision and 32% in association with screen printing coverage.

Since the practice was founded by Rachel Haugh and Ian Simpson in 1987, it has compiled an impressive portfolio of award-winning projects. It originated from a shared belief in the power of high quality design to lead the regeneration of post-industrial cities and initiate new contemporary architectural identities. Main themes are urban renewal, sustainability and design excellence with the aim of designing buildings and spaces that would be appropriate, inspirational and beautiful. While the success of its completed work and growing reputation for design integrity has allowed the practice to expand, Rachel and Ian remain personally involved in each project. Consequently, the inspiration in design and the attention to detail in construction that have stimulated the achievements of the practice so far will continue to guide its schemes in the future.

Deansgate Square


Deansgate Square towers are clad using a fully glazed unitised, glazed curtain walling system with different panel types - fully fritted glass, partially fritted glass, rapid vents and clear glazing - arranged in a regular geometric composition, creating a uniform façade pattern over the full length and width of the towers.

A total of over 17,000 units were produced for this project, of which 5,600 cover the South Tower up to its renowned and exclusive 65th floor exclusively dedicated to panoramic “penthouses”.

Set within landscaped public space next to Manchester's River Medlock on Owen Street, this high-density development creates a new destination for central city living. Located on the site of a former public car park area, the scheme reinforces and supports the Great Jackson Street Development Framework (which we also prepared) by generating a critical mass of population to activate the site and providing a quality benchmark for future development nearby.

Generous facilities throughout are unparalleled for a residential development in Manchester. Residents can access a tennis court, swimming pool, cinema, gym, studios and three basement car parking levels. The public benefits too from cafés and restaurants and new pedestrian links via new public spaces at the base of each tower and immediately adjacent to the River Medlock.

Deansgate Square delivers 1508 homes within the four towers. Standing at 67 storeys and 200m high, the tallest building is the second highest residential tower in the UK. The other buildings stand at 53, 47 and 40 storeys high. Two subtle design features emphasize the verticality of the towers. A 1m indentation on each tower face creates a vertical crease, breaking down each surface into two narrower planes. Adjacent tower faces receive subtly different colour tones, silver grey and anthracite, emphasising the crisp vertical lines of the four corners of each building.


It is a fully transparent glazed unit with natural anodised aluminium frame and RAL 7021-7037 aluminium bulkhead (depending on the relevant elevation) to integrate the 450mm ceiling - false ceiling package.

-typical vision glazing consisting of 10/16/55.4 heat strengthened glass panes with Low-E #3 coating (iplus advanced 1.0T by Agc) and argon. Partial application of silk printing RAL 7031 or RAL 7047 (upon the elevation) on face #2.

-typical spandrel glazing consisting of enamelled 10/18/10 RAL 7021 #3. Partial application of silk printing RAL 7031 or RAL 7047 (upon the elevation) on face #2.


For this projct we have designed and manufactured about 500 units with typical dimension of 750mm width, natural anodised aluminium door frame with insulated panel named “Purge Vent” (ventilation panel) H=2400mm with transom panel H. 450mm. The frame finish is bi-coloured, internally it maintains the natural anodised finish like the other internal profiles, externally the profiles and sheet metal are anodised black.

The area of the transom panel has been engineered to insert a specific ventilation Ductwork, allowing the exchange of recirculating air for bathrooms and kitchens of the individual apartments.

The detail was bespoke designed on a specific fluid dynamics study, then validated and tested at the independent laboratory BSRIA (Bracknell, Berkshire, UK)

The external structural fall-arrest barrier consists of a 4 mm anodised aluminium alloy panel in two shades of light and dark grey. It is perforated with a pattern specifically designed by the architect to create a strong play of cast shadows.

This barrier guarantees protection from falling and it has been statically calculated and tested to withstand a linear load of 0.74 kN/m and a concentrated point load of 0.5 kN (in compliance with BS6180) without any permanent deformation.
