{"product_id":"loft-conversions-isbn-9781118400043","title":"Loft Conversions","description":"Pressure on space and changes in planning law mean that loft conversions are now at the forefront in the race to improve the performance of Britain's ageing housing stock. Since 1990, roof space conversions have increased UK housing capacity by more than 200 million square feet - a living area equivalent to a medium-sized city - without the loss of a single square foot of greenfield land.\u003cbr\u003e\u003cbr\u003e\u003ci\u003eLoft Conversions\u003c\/i\u003e is the definitive technical guide to the conversion of roof spaces in single family dwellings. It brings together a wealth of practical and regulatory guidance in a form that is easy to read and comprehensively illustrated.\u003cbr\u003e\u003cbr\u003eThis fully revised and updated second edition is intended primarily for architects, builders, surveyors and others professionally involved in the process of loft conversion. The insights it provides are also invaluable to self-builders and to householders wishing to achieve a deeper understanding of what a loft conversion involves. \u003cp\u003ePreface xiii\u003c\/p\u003e

Since 1990, roof space conversions have increased UK housing capacity by more than 200 million square feet – a living area equivalent to a mediumsized city – without the loss of a single square foot of greenfield land.  \u003c\/p\u003e\u003cp\u003e\u003ci\u003eLoft Conversions\u003c\/i\u003e is the definitive technical guide to the conversion of roof spaces in single family dwellings.
