The Olympic Village consists of 11 blocks, each block comprising between six and eight individual buildings, which are eight to twelve storeys high. Of the many amenities in the Village, by far the largest usage is for apartments, of which there are around 3000 units.

Despite the height and density of the scheme, it has a surprisingly open feel, aided by the glazed winter gardens and mostly generous sized balconies, which are very much in evidence throughout the entire development. There was a huge demand here for the Schöck Isokorb®, with around 10,000 thermally broken structural connections to be considered. For podium slabs and pre-cast balcony applications the Isokorb® type K, for concrete-to-concrete connectivity was used. The type KST, type QP and Schöck SLD dowels combined to meet the requirement for securing the winter garden balconies. Types KS14 and KS20 for steel-to-concrete, provided the solution for connecting the various concrete frames to steel balconies.Some of the steel balconies had a cantilever length of approximately two metres and in most cases KS20 units offered the ideal solution. However, in certain locations – concrete edge beams for example – the reinforcement bars had to be shaped to suit and for these applications special KS14 modules were utilised.

The unusual T-shaped winter gardens provided one of the greater challenges. Remarkably, the winter garden concrete slabs are designed to span two building blocks – approximately seven metres – and it was essential to allow for movement of the slabs by combining the Isokorb® type QP at one end and SLD dowels at the other.

Exceptionally strong steel-to-concrete thermal break connections were required and usually the Isokorb® type KS would be the natural choice. On this occasion however, the forces involved exceeded even the capabilities of the KS units and it was necessary to design a KST configuration, in combination with a specially developed steel bracket. Back at ground and first floor levels a huge number of type K concrete-to-concrete thermal breaks were required for the large slab sections. In some cases the extreme dimensions of the slab sections resulted in thermal movement beyond the Isokorb®'s capability and SLD dowels were used in their place.
