More Information

Launch sell out

Such is the popularity of Four Hundred Caledonian Road that units sold out entirely at launch. The commercial spaces are filled by creative businesses, including the scheme designers Brady Mallalieu Architects.

Fabric first

igloo used a fabric first approach to designing the building, meaning the components and materials used were chosen to optimise performance. Time has been spent considering elements like the wall, floors, windows, roofs and insulation.

Sustainability as standard

As a result of the¬†sustainable approach to design, heat loss from the building is very low, with a fabric performance that is 40% higher than the Building Regulation standard. In addition, an efficient communal Combined Heat and Power (CHP) engine produces heat and electricity for the homes. Mechanical Ventilation and Heat Recovery (MVHR) brings fresh air into the home without heat loss, and ‘green’ roofs provide added layers of insulation.

HIgh-spec and high-tech

The homes all boast cutting edge technology. There are Neo Wi-Fi connected thermostats in each room, which can be controlled via mobile devices, and underfloor heating with sustainably sourced bamboo flooring. Each home has its own outdoor space and large balconies, as well as access to two green courtyards and cycle storage.
