Lofts in Stratford divide sharply between historic buildings, where the roof is part of what is protected, and modern housing, where a conversion is routine.
In a timber framed or historic building the roof structure is frequently original fabric, and in a listed building it is covered by the listing. That does not rule a conversion out, but it does mean the design works around the historic timbers rather than cutting through them, and that any new structure is introduced in a way that could in principle be reversed. It is a design problem with good answers and it is emphatically not a job to price from the pavement.
Head height in older buildings is the other early question, and it is frequently the one that ends the conversation. These roofs were not built for standing room, and we measure at the quotation rather than after.
On the modern housing out towards Shottery and Tiddington the roofs are trussed, which means the structure gets reworked rather than strengthened. Routine work for us and not the same job or the same price as a cut roof.
The permitted development volume allowance is forty cubic metres on a terrace and fifty on a semi or detached house. A dormer facing the road is not permitted development anywhere, and in Stratford’s conservation areas anything altering the roofline the street can see will be examined very closely indeed. Our loft conversion page goes through the structural options.
