Is a dormer conversion right for me?

A dormer is where part of your existing sloped roof is replaced with a box-shaped extension to maximise headspace and usable floor area.

The addition of well-placed windows can bathe your new space with natural light, so consider where the sun moves through the day to inform your floorpan. If you benefit from spectacular views, full width sliding doors with a Juliet balcony can maximise the panorama.

A dormer conversion is favourable choice over a VELUX conversion if you are looking to maximise design options, which often enables the creation of multiple rooms (e.g. adding an en-suite).

A style to suit

Full-width, flat-roof dormers are usually found at the rear of a property, and pitched-roof dormer conversions at the front of a house.

Rear dormers are typically cladded or rendered. There are many finishes and colours available including innovative composite woods made from recycled fibres, to self-colour renders which require little maintenance. Choice ultimately comes down to the style of your house and personal preference.

Pitched roof dormers can be faced with brick, render, or cladded to be sympathetic with the style and age of your house or surrounding properties.

Local planning may require use of specific materials or finishes so it’s worth contacting your local council for guidance. Planning rules may differ from street-to-street, though it’s always a positive indicator if a neighbouring property has used materials that you wish to employ – it’s definitely worth a walk around your local area to do a bit of research.

Need some advice? Simply call us to discuss your project or for a no-obligation home visit.

  • Dormers maximise the potential floor space thanks to increased headroom
  • A dormer conversion will typically add more value to your property than a roof light conversion
  • A large panoramic window or balcony can give your dormer conversion an added wow factor
  • Increased design freedom means your roof space can often be converted into multiple rooms
  • Planning permission may be required for a dormer conversion – it is advisable to consult the local planning authority to understand any requirements or restrictions before you invest in any plans and drawings
  • A dormer conversion requires more structural changes compared to a VELUX conversion which will increase budget and construction timelines

How long will it take?

From a construction perspective, a standard dormer loft conversion can take between 4-8 weeks to complete. This also takes electrics and plastering into consideration.

As dormers provide you with increased design freedom, there may be certain aspects which influence your project’s duration, for example including an en-suite.

Do factor upfront timings for architectural drawings, structural calculations and approval from your local planning authority. We can discuss this aspect of the project during your initial home visit.
