Because the labour is semiskilled, it helps to keep build costs down too. There was also a wider emphasis on using local suppliers and labour on the job and, according to Beattie Passive estimates, for every £1 spent on the Bradwell project, £2.84 was circulated back into the local economy. Beattie Passive has published a breakdown of the costs for two of the certified passive houses at Bradwell on its website: The total build cost was £65,785 per unit, which comes to £842 per square metre or £78 per square foot, including all labour, internal finishes and external render, but not external site works, preliminaries, fees, overheads, profit and services. “To make passive work it’s got to be at the same price as standard building costs,” says Ron, “Beattie Passive is.” The Bradwell houses are primarily heated with u
