Guide to Loft Conversions in Dorking

Our company completes high-quality loft conversions for homeowners throughout Dorking. This includes transforming forgotten attic spaces with new bedrooms or bathroom installations. Larger remodelling work involving mansard property extensions requires planning permission from the local authorities. Our designers and builders ensure loft conversions comply with building regulations for any size project and we manage any property maintenance you need too.



Loft Conversions



Dormer windows and lofts are popular designs for bedrooms and bathroom installations, including en suites. These loft conversions extend outwards with a flat or hipped roof to add more head room and floor space. Our builders efficiently install dormer lofts at the rear of your Dorking property. Loft conversions which measure the full width of the property or positioned at the front or side of your home require planning permission. We complete any property maintenance for the rest of the loft to accommodate new dormer windows.


Hip to Gable

A ‘hipped’ roof is the traditional pitched shape with sloped sides. These are like dormer lofts, which extend outwards from the existing roof. Builders complete hip to gable loft conversions by adding the new hipped aesthetic that blends in with the existing roof at your Dorking property. Property maintenance experts ensure new roofs are fully insulated and damp proof.



Mansard property extensions span the full length of the property. Our builders carry out extensive work to alter the original pitched shape into a 72° angle roof. The extra floor to your home is ideal for master bedrooms or family-size bathroom installations. Permits from the Dorking Council need to be obtained before construction on mansard property extensions can commence.



Planning Permission


We recommend applying for planning permission as early as possible. When extensions and renovations like bathroom installations have been decided upon, our professional designers and builders help Dorking customers with the submission process. Because this can take up to 8 weeks, we assist with the application and liaise with local authorities on your behalf.


Planning permission is required for the following loft conversions at your Dorking property:


  • If loft conversions at terraced houses exceed 40 cubic metres or if they exceed 50 cubic metres in total at detached and semi-detached homes. This applies to other property extensions at your Dorking property
  • If the height of loft conversions is higher than the apex of the roof
  • If loft conversions or property extensions extend further than the roof plane
  • If builders don’t use materials that match the exteriors of the Dorking property
  • If balconies, verandas or raised platforms are installed
  • If loft conversions with windows at the side of the property aren’t obscured for privacy
  • If window openings measure less than 1.7m above the floor
  • If dormer or hip to gable loft conversions are less than 20cm from the existing eaves
  • If your Dorking property is a listed building or located on a British Heritage site or conservation area
