A NEW 21ST CENTURY LANDMARK FOR SOHO

PREVIEW DOCUMENT

A NEW 21ST CENTURY LANDMARK FOR SOHO HISTORY AND VISION 11 Soho Street is a brand new building, but architects AHMM have taken their inspiration from historical sources, including the architectural history of retail. As retailers embraced new technological advances such as curved glass, so the exterior of shops changed in order to encourage browsing and sales. Taking this historical reference, and examples of architecture in the area, AHMM developed a language of curved glass for the whole facade, taking further inspiration from the curved lines of 1937 design classic, the Aalto vase. The previous building on the site, whilst not of merit, possessed a corner tower feature that gave it a note of architectural interest. AHMM chose to replace this feature with a new corner of architectural distinction, to continue the landmark contribution that the site made to the wider townscape. The new design, a striking lantern, is composed of flat and curved glass elements, arranged to articulate the three different functions of the building and to create a rippling and sensuous curvilinear glass skin.

The ceilings will incorporate a Zumtobel surface mounted Superhighway Introduction The building envelope along Soho Street and Oxford Street is composed of flat and curved glass elements, arranged to articulate the three different functions of the building and to create a rippling and sensuous curvilinear glass skin. The facade design is based on a stick system assembly to single glazed shop-front areas and on a unitized system to the double glazed facade portions on the upper floors. The North and East facing street elevations feature floor to ceiling glazing to maximise views and daylight penetration deep into the floor plate. The use of pure white low iron glass has been adopted to maximise transparency and to achieve an un-tinted clear appearance of the building. 6m modules of flat and curved single glazed elements define the Retail facade to Ground and First Floor. The 2 Office floors are articulated by 1.5m modules with the variation in width taken up by flat glass panels allowing the bespoke curved elements to remain the same throughout. The Residential units on the fifth floor are composed of curved panels in 1.5m bays with concave and convex panels alternating along both street elevations. system enclosing the fire and electrical services, and fitted with a Dali based addressable lighting system with opal diffusers. The glazed perimeter will be illuminated by uniformed surface mounted downlights. The perimeter walls of the office space facing Oxford St. and Soho St. will be a full height curvilinear fritted glazed system with white PPC Aluminium mullions and transoms. A curved curtain track is fitted for tenants own curtains (from a specified range). The core walls and southern facade will be finished in white plasterboard. Office areas also include roof terraces which are described in the External Treatment section. A radius of 600 mm has been adopted as a threshold to allow for an increased number of coatings applicable and to improve competition and quality control. The south facing elevations towards the inside of the urban block are terraced and feature a more conventional approach of a solid wall with punched floor to ceiling windows and doors. The solid areas of the facade here are clad with bespoke white glazed terracotta panels echoing the curved nature of the street elevations at a smaller scale and function as a rainscreen cladding. Main Office Cladding Using tested framing and assembly methods for the curtain walling system will enable the erection of the bespoke facade in a proven, conventional way minimizing the risks and reducing construction times. Both the bespoke and the standard double glazed units will be individually prefabricated and assembled in a factory to the highest standards; delivered and installed on site ensuring the highest achievable quality of finished facade. EXTERNAL TREATMENT CONTINUED MECHANICAL SERVICES The glass treatment on both street facades also involves a ceramic frit pattern of translucent graded dots to blend in the opaque zone of slab edge including the raised floor into the transparent areas above and below. Office Entrance The two office floors share a common entrance into the building from Soho Street protected with a top lit stainless steel canopy leading towards a glass clad entrance lobby with a reception desk and a small leather clad waiting area. The flooring is made from grey terrazzo slabs throughout and into the lifts. Air Conditioning system: Ventilation system & smoke ventilation Heating, cooling and fresh air to the office areas is provided by an underfloor air conditioning system. Dedicated zone units delivering conditioned air to the floor void are provided for each office tenant demise. Each unit consists of re-circulating inverter driven fan, filter and DX coil located within an acoustically treated cupboard. Each zone unit is connected via refrigerant pipework to its own external condenser, located within the roof plant enclosure. The zone unit supplies pre-heated or pre-cooled air to the floor void, from where it is distributed to the space via local environmental units, i.e. an intelligent floor tile with a fan and return air grille. The fan tile maintains the local set temperature by mixing supply air from the zone unit with re-circulated air from the space. The fan tiles may work in 4 different modes: Cooling mode If the underfloor temperature is below the room air temperature, the damper is modulated open to allow cooling to the space. Heating mode If the underfloor temperature is above the room air temperature, the damper is modulated open to allow heating to the space. Roof Terraces Both offices and residential floors have access to south facing terraces of various sizes and shapes. All terraces are paved with high quality concrete paving slabs. The main roof features a living brown roof outside the plantroom area with Photovoltaic solar panels attached to the plantroom screen as well as above the brown roof. Recirculating mode When the room sensor detects that the local temperature matches the set point, the damper will be closed and the unit will be in recirculation mode. An adjustable bleed damper allows sufficient air from the floor void to provide the fresh air requirements for the space. Electric heat mode Under exceptional circumstances, if the room temperature is too cold and there is insufficient heat available, the controller will modulate the damper fully closed and initiate the electric heater battery. Each fan tile may be relocated to suit future tenants fit out requirements.spent air from the space is returned to the zone units via floor return air grilles and a dedicated return air path within the floor void. The system is designed to run the fans in out-of-hours to provide free cooling. Ventilation system Fresh air to the office areas is drawn from the landlord s central fresh air shaft. A dedicated constant air volume box with supply fan, heater battery and filters, is provided for each office tenant within the floor void, supplying a pre-set volume of fresh air to the supply air floor zone. An additional constant air volume box is provided for each tenant within the floor void to control the amount of return air extracted to the exhaust air shaft. A set of landlord s extract fans inside the main shaft draw the return air into the shaft and discharge at roof level.

MECHANICAL SERVICES CONTINUED Smoke Ventilation system One wall mounted grille with normally closed motorised damper is provided for each tenant. In the case of a fire, the motorised dampers on the exhaust system will open to allow smoke to be extracted from the space. Landlord s run and stand-by extract fans will switch into smoke extract mode and fresh air motorised dampers will open to provide make-up air. Toilets Toilets are served from the main extract system. Air is extracted from each cubicle via circular ceiling mounted extract valves. Cross talk attenuators are provided in accordance with the acoustic requirements.
