By Adam Challis, Head of Residential Research, JLL In my first proper job, I had the opportunity to help organise a sales conference for a carpet manufacturer. We called it the 'Wall to Wall Conference'. Thankfully my stint as a marketeer was short lived. I came across the same company many years later when analysing the purpose-built private rented sector in the United States. One investor/ landlord talked to me about the bedroom sizes, which were a specific width to fit a standard roll of carpet. Fewer cuts meant less wastage, faster turnaround between tenancies, and bluntly, contributed to more profitable buildings. The investor had thousands more homes planned, chock full of tiny tweaks to standard building practices that drove better returns. I like this little anecdote in the context of Space Standards, because it reminds me of how far away they are from serving any commercial purpose. On a good day they represent a planning simplification of what would otherwise be quite complex issues of design quality. On a bad day, they represent a lazy proxy for design standards.
