VW Group UK Financial Services

SuDS underpin sustainable headquarters


Milton Keynes is the location of the New Headquarters for Volkswagen Financial Services (UK), a landmark building, providing a physical representation of the VW Group brand that is manifested in the building’s exterior and interior design. Construction of the building commenced in 2013; the offices were opened to employees on 5 Jan 2015 and officially opened by Business Secretary, Vince Cable, on 11 March. The building provides long term premises for VW Group Financial Services in close proximity to the UK offices of the Group’s automotive brands.


The 4-storey building, which has been shortlisted for a BCO (British Council for Offices) Award, is constructed to BREEAM Grade A ‘Excellent’ standard and is equipped with 82 roof mounted solar panels, producing 40,000kW per year, and multiple charge points for use with electric vehicles. Inside, the building provides 100,000 square feet of office space, spread across 4 floors, along with a staff restaurant, coffee shop and conference centre, whilst, outside, the staff car park and bicycle storage facility are supplemented by green space designed to complement the style of the building.

How it works

The SuDS system is required to handle surface water from a 1 in 100 year storm with an additional allowance of 30% for climate change. This ensures that the site will remain free of flooding from prolonged, extensive rainfall which is anticipated to become more frequent and intense in line with climate change.


SDS was engaged to supply every aspect of the drainage system (with the sole exception of the manholes).


2 GEOlight® tanks have been installed, supported by Channel Drainage and 9 Vortex Flow Controls, and over 2,500 square metres of Permeable Block Paving.


SDS embraced the invitation to design a surface water drainage system that would complement the client’s requirements for a high quality sustainable development.


SDS was able to deliver substantial cost savings through value engineering the design of this installation.


Sean O’Connor, Site Manager, VINCI Construction: “Having reviewed our requirements, SDS took the initiative to design and value engineer a bespoke system, enabling us to pass on significant savings to our client. Their innovative design involved several stages of surface water treatment and was crucial to securing planning approval from the Council and the Environment Agency.

What our other Customers say

The installation of a system comprising a device of concrete construction, until now our only option, would have required the use of a 350 tonne crane and most likely, due to the massive inconvenience not just to us but to the airport and local road network, would not have been feasible at all. The Aqua-Swirl™’s versatility meant that we could design the devices for the specific requirements of this site, without the need for any bends in piping, whilst their inherent strength allowed us to save on time and cost through not requiring a concrete surround. Their compact size and small footprint, together with the lifting supports and straps provided, meant installation was very quick and simple and final placement could be done manually; we needed only a single day in which to dig, position, connect up and back fill.
