im planning to increase my home living quarters by adding two rooms downstairs. a single story side extension to my lovely semi detached house.
the single storey side extension will be 4m wide and the total span length wise will be 12.5m. the roof space / atitic space will (im assuming) be quite massive?
the info im after and the help i need is calculating how much space i will get under this new roof to play with (perhaps enough to accomodate a spare bedroom?)
anyone know of any websites or information for calculating potential roof space on such projects
thanks in advance
