Twitter - Cumberland House

Twitter

The Twitter fit out project in Cumberland House encompassed 120,000 sq. ft. of Cat A/ Cat B corporate HQ office & ancillary accommodation spaces (including a full commercial kitchen/ dining facility) over six floors.

Challenges

The original 1970’s structure which was retained as part of the refurbishment was constructed based on a natural ventilation solution and without raised access floors which proved a challenge from a space perspective to transform the building into modern & flexible air-conditioned commercial offices.

Successes

This project achieved LEED Platinum & B3 BER certification & the maximum floor to ceiling space was delivered via the use of exposed services with minimum cross overs within a service zone of 375mm and in our opinion this level of co-ordination was key to the success of the building & Twitter Fit-Out. The refurbishment/ extension of Cumberland House & the subsequent completion of the Twitter Fit-out and was the catalyst for the transformation of Fenian Street from a commercial perspective.

Metec Solutions

Given the restricted slab to slab dimensions of the existing floors in Cumberland House and the fact that the existing building did not have a raised access floors Metec Consulting Engineers employed a highly co-ordinated Air-Conditioned HVAC System in addition to the installation of in slab fire rated cable hives on a grid basis with IT & Power Cabling fed via the floor below to serve the Twitter workstation clusters/ cellular spaces.

Building Services

  • The provision of a dedicated Electrical Sub-Station suite to serve both the Landlord & Anchor Tenant Power Supplies at 20 kV Medium Voltage in addition to the facility to provide Low Tension 400 volt CT Tenant Metering on a floor by floor.

  • The LEED Platinum certified design included the provision of a highly efficiency central Chiller & LPHW generation plant, high level fan-coil units, automated Lighting controls c/w presence detection and daylight sensing and Variable Frequency Drive Vertical Lift Systems.

  • The Twitter Fit-out also encompassed a Comprehensive IP based CCTV, Door Access Control & Intruder Alarm system throughout the building that was linked to a central security centre for monitoring & control.
