We were asked to assess GVA’s new environmentally friendly international London Headquarters. The headquarters would provide a contemporary, flexible and welcoming office environment for staff, clients and visitors and the space would enable GVA to retain, recruit and nurture the best talent.

The office design and delivery was to be officially certified with a SKA rating, with an initial aspiration of achieving a Silver SKA rating. The space also needed to support agile working and increased productivity, whilst also reducing environmental impacts through occupation.

The space needed to follow five sustainability aspirations:

  • Design spaces for productivity
  • Optimise the indoor environment
  • Use sustainable materials and reduce waste
  • Act to minimise energy and waste use
  • Engage to improve

Initially GVA targeted a Silver SKA rating, however this soon increased to a Gold. We were able to enhance our service to GVA by offering solutions both to the client and the design team on materials and advise on achieving SKA Gold.

We worked closely with the internal client and project manager team, appointed design consultants and engineers, providing them with SKA and sustainability guidance workshops. These were arranged to help the internal team understand the project and discuss which measures should be set as targets. They also assisted the achievement of specific SKA measures.

We initially identified 84 measures in scope, 75 of these were targeted. We continually monitored and managed the scope, which was adjusted throughout the project. By the Handover Stage, 85 measures were identified in scope, 72 of these were targeted and 68 were achieved.

The ‘At Risk’ GPMs we identified in the project went up rapidly after the start of the Handover Stage. We were gradually able to reduce the risk, and with the support of the contractor team, the risk level was just above 0 by the end of the Handover Stage.

As part of a whole project work reduction strategy, we helped the client to devise a ‘reuse and recycling’ strategy for the existing furniture. The furniture would either be retained or reused by GVA, reused on another site, sold to staff for reuse, sold elsewhere for reuse, or be recycled by a third party.

SKA rating was used as a supporting framework for the project, however issues beyond this were also considered. These included decisions made on items that had long-term returns such as occupant wellbeing and brand value return. Unique actions on this project included the introduction of the CO2 and VOC meters to monitor air purity throughout occupancy.

Appointment of the contractor team was based on their knowledge of SKA rating for which we were able to assist the client and project manager. Overbury were appointed as they had the strongest team, experience and achievements on SKA projects.

GVA Gresham Street managed to achieve a Gold SKA rating. This was an incredibly proud moment as GVA Gresham Street is Grigoriou Interiors’ first Gold SKA rating! Client commitment to this goal made a massive difference and was fundamental in the achievement of the rating.​

We were delighted to achieve a Gold Ska Rating for the fit-out of our new London HQ in February 2015. Elina provided assessment of the project but more important was her advisory capacity. We brought Elina onto the project early on and I would advise the earlier the better. She guided the project team through the Ska Rating process and requirements, helped on aspects of strategy and ran workshops with the contractors. Her on-going advise on aspects such as materials, products and waste was highly valued by the design and fit-out teams. Elina always brought enthusiasm and positivity to the project but also never shied away from asking the difficult questions. Elina certainly delivered on her service promises and provided excellent value for money. I recommend Elina to any team wishing to embed environmental and wellbeing aspects into their fit-out and she is the expert on Ska Rating.
