Why Splash Out On a Loft Conversion?

Choosing to have a loft conversion is a great home improvement to expand your living space without the expense and hassle of finding a larger property, according to Mike Pritchard who runs the company Chiswick Loft Specialists. Almost every house can be extended via a loft conversion, although the ease and convenience of this project depends on the construction of the property.

There are many reasons why people choose to extend their property into their roof space. Often, growing families need an extra bedroom as they have more children, or sometimes families need more space if an elderly relative comes to live with them. Sometimes, couples like to expand into their roof space to make an attractive loft bedroom with en suite, and loft conversions also make a great study space.

Types Of Loft Conversion

There are four major types of loft conversion:

Velux Conversion

This method is popular as it usually does not require planning permission. In this type of project, the roof structure is not altered, but rooflights are fitted to give natural light to the room inside. This type of conversion is suitable if there is an adequate amount of headroom in the existing loft space.


There are four types of dormer conversion which alter the look of a property from the outside. All give extra floor and headroom by building a protruding extension from the roof of the house.


A mansard extension is a great way to get maximum floor space from your loft. It raises both walls on either side of the property’s roof and fills in the space with a timber framed structure.

Hip To Gable

A hip to gable extension builds onto the side of the house, raising the gable wall and filling in the gap with a new roof. This is useful in homes that have limited internal space.

Loft Conversion Rules

Many loft conversions do not require planning permission as long as the existing roof space is not extended or altered beyond the existing limits of 40 cubic metres for terraced properties and 50 cubic metres for detached and semi-detached homes. Building materials must be similar to the ones used in the original construction of the property, and the extension must not reach beyond the plane of the current roof slope at the front of the property. It must also extend no higher than the existing roof. There are also rules regarding obscuring of side windows which must be over 1.7m from the floor. In certain areas, such as conservation sites and areas of oustanding natural beauty, there can be no roof extensions. Any loft conversion must be carried out with due care and attention when bats may be nesting in the property and a licence may be required in these cases. All loft conversion work is subject to building regulations approval.
