A guide to Loft Conversions In London

A huge premium for space exists in London. With house prices rising over the past 20 years across London, converting a loft or extending a home has been a tried and tested way of adding value to properties with the additional value added far outweighing the cost of build.

Moreover, over the past decade planning regulations have been simplified! As a result we have witnessed a huge upsurge in the number of households opting to convert their lofts with some households no longer requiring planning permission. Our team can help establish the pertinent requirements for your property as it may be possible to convert your loft under Permitted Development regulations.

Different types of Loft conversions In LONDON

There are several different types of loft conversions in London that you can have built on your home, the main three types are Dormer conversions, Hip to Gable conversions and Mansard conversions. The type of loft conversion that is suitable for your property will depend on a number of different aspects of your loft (e.g. the size or square footage; how you plan on utilising the space; the planning permission that is likely to be granted, if required).

Feel free to call or email us to discuss which type of loft conversion is most suitable for your property.

Dormer Loft Conversion

The most common type of loft conversion;

• A Dormer loft conversion includes a vertical wall from the bottom of your sloping roof. A flat roof is then built to meet the vertical wall, allowing maximum headroom in the new loft extension.

• It is unlikely that you will need to obtain planning permission for it.

• This type of conversion can also be gable or have a hipped roof

Mansard Loft Conversion

• With mansard loft conversions the gable or dual-party walls (dependant on whether your property is detached or a terraced) are raised to make a to a certain degree vertical – minimum 72° – profile for the mansard. A horizontal cross section and timber framing is then incorporated.

• A very common method of loft conversion, typically found in built up areas where terraced properties are more common

• Typically requires planning permission and windows within Mansard Loft conversions will be housed within the dormers.



Hip to Gable Loft Conversion

• Hip to gable loft conversions aim to maximize a smaller existing space of a property with a hipped roof. The sloping side of a roof is adjusted to a flat gable end to increase the overall space within the conversion.

• A hip to gable loft conversion achieves lots of heads space and as a result is suitable for a variety of uses such as: additional living space, office space and playrooms/entertainment rooms.

• Only suitable for properties which are detached, semi detached or a bungalow.
