Planning permission is not normally required for a Garage Conversion in Essex or Suffolk,however Building Regulations are required for a habitable room.
However,there are occasions when that does not apply,and these instances are usually related to the fact that the property is a listed building.
Another reason why permission may be required is that something called permitted development rights have been removed from a property. This is a rare occurrence but can occur in new houses on estates.
Also a walk in bay that extends past the property line will require a planning application.
The change of use from a garage to a habitable room will mean compliance with building notice to your council.
Building regs apply to ventilation,insulation,moisture proofing,fireproofing and escape routes.
The building inspector will want to inspect the windows,doors,dpm,insulation.
The existing garage floor will be strong enough however it will need a 1200 gauge damp proof membrane and rigid insulation of at least 75mm to meet the regulations.
External walls must meet the requirements in terms of moisture proofing and thermal barriers.
We tend to build another wall alongside the existing outer wall with a 50mm cavity,100 mm insulation,a vapour barrier and then plasterboard.
