Summary:

A complex mixed-use development, above platforms 12 to 19, at Victoria Station. An extension of two existing buildings, 123 and 151 Buckingham Palace Road (BPR), the HUB Victoria comprises three distinct buildings, connected by a landscaped public realm, with curated retail and leisure:

• SKYHUB: 
  Three-story rooftop extension, providing:
• 107,000 sq. ft. of brand new Grade A office space
• 12,000 sq. ft. of dedicated outdoor terracing with amazing views
• Shell and core reduce excess waste

• 123HUB: 
  200,000 sq. ft. of existing office space + home to Google and WeWork
• 151HUB: 
  200,000 sq. ft., best in class CAT A space, across ground + 5 upper floors
• 123 + 151:
  Retail units, flexible design for potential tenants
  
  

Engineering services:

• Input from Stage 0–7 (inception to completion)
• Assessing pre-existing and dated services and their impact on works
• Re-using existing plants and services reduces embodied carbon
• Reconfiguring existing high-voltage network
• Relocating existing or additional plant to new SKYHUB roof
• A new VRV system installed, along with new AHU equipment for additional office space and 16,000 sq ft of retail space
• The design of CAT A fits out of all six 151 floors (including ground)

Energy and Sustainability Services:

• BREEAM Consultancy
• Life Cycle Costing
• Thermal Comfort Assessment
• Passive Design and LZC Assessment
• Daylighting Assessment

Challenges Overcome:

• Working above a major train station within building constraints, e.g. existing deep structure of 151 BPR
• The building remained partially occupied throughout extension and refurbishment; it needed to remain operational, and tenants were unaffected
• Considerable phasing of work occurs, for example, when:
• Relocating or diverting existing cooling plant and capacities
• Relocating plant from old roof to new SKYHUB roof

Result:

HUB Victoria is the result of major improvements to ground-floor retail spaces, office entrances, and the public realm, adding a substantial rooftop extension to the building with its own dedicated entrance.

In addition, the development benefits from considerable sustainability achievements:

• BREEAM 'Excellent'
• EPC target of A and B
• 11/12 score in BREEAM energy credits 
• 9/9 score in BREEAM water credits
• Integrated energy-efficient measures and LZC technologies result in substantial carbon savings of:
• 59.4% from energy demand reduction
• 8.6% from renewable energy
• 62.9% (cumulative) across all stages of the energy hierarchy
