At 437 keys the hotel at Heathrow is the largest of the new Marriot brand, Moxy Hotels in Europe. The cores and level 1 slab were traditional steel frame construction with the rest of the building formed from Cross Laminated Timber (CLT) slabs which create a rigid cellular structure. The CLT section of the building was prefabricated in Italy as double bathroom pods with the walls prewired and preboarded almost totally removing the fitting out of the bedrooms from the critical path.
The construction of the hotel directly under the Heathrow flight path proved particularly challenging and was ultimately achieved without working at night and without affecting the speed of construction of the CLT rooms. Value engineering was a major driver for the Project, BSB drove the cost plan down to a level which allowed the project to proceed and then kept a tight rein on expenditure throughout the build.
