LPS know loft conversions...very well. Not only have we designed hundreds of conversions across London and the South-East but we have also built them, so we know better then anybody the limitations and possibilities. 

Let our in-house specialist architectural designers produce the loft conversion you want!

Planning permission is not normally required for this type of project assuming the design and your property falls within the permitted development policies.
However you will need a certificate of lawfulness which will not only ensure that what you are proposing to build is lawful but also that there is not legal issues in the future when you come to sell the property.
