Schöck Isokorb for award winning ‘Sky-House’ scheme


The ‘Sky-House’ development, at Oughtibridge Mill to the north of Sheffield, comprises forty high-specification homes. The term ‘Sky-House’ being derived from the spacious feel of the properties, which benefit from unrivalled views and offer bright and airy living, complete with riverside balconies.

Designed by CODA Architecture, it is built very much with sustainability in mind and minimising any risk of thermal bridging at the balcony detailing is critical. The load-bearing structural thermal break that easily achieves this; and most effectively helps the project meet compliance with the necessary Building Regulations (and the impending Future Homes Standard criteria) is the Schöck Isokorb. Specifically it is the Schöck Isokorb T type SK for concrete-to-steel connectivity that is incorporated at Oughtibridge Mill. This is a complete system thermal break. It is unique in being the only formally UK approved product that satisfies the load-bearing and thermal insulation requirements for this type of application, providing assurance to the end-user that the safest product has been selected for their building needs.

The avoidance of thermal bridging is extremely important for a number of reasons. Any local heat loss will result in more energy being required to maintain the internal temperature of the building. Also, low internal surface temperatures in the area of any thermal bridge can cause condensation and this in turn is likely to result in structural integrity problems. Mould growth too is a possible risk, which in a residential situation can cause asthma and allergies.

Award winning scheme

Oughtibridge Mill ‘Sky-House’ is an award winning scheme – recipient of the Development of the Year (fewer than 50 homes) at the Insider Yorkshire

Property Industry Awards 2021. It is part of a wider scheme for 320 new homes that will enable the regeneration of this former industrial mill site. It had been a flourishing paper mill from Victorian times until its closure in 2007 and renovation of the old mill building for use as a mixed-use food hall, community hub and leisure facility is underway. To reference the industrial history of the area, a sensitive contemporary design style features saw-toothed roofs on the three and four-bed townhouses.
