Dormer Roof Extensions and Windows

Dormers: Roof Extension & Dormer Windows

Dormer conversion, Macclesfield, Cheshire

The word dormer originates from the Latin for sleep, 'dormir'.

Sleeping rooms, 'dormers', today describe one of two styles of roof loft:

1. A vertical window set into a gable projecting from a sloping roof.
2. A loft conversion or extension generally with a flat roof and vertical sides.

Structural difference between dormer windows and extensions tends to be one of scale.

1. Dormer Windows

Eyebrow dormer

Dormer windows are an attractive and stylish roof addition.

Dormer windows increase headroom within a loft and often span only the width between adjoining rafters, using them as support for the dormer frame.

2. Dormer Extensions

Dormer Extension

Dormer extensions require a much broader roof frame and removal of rafter sections during framing.

The existing roof is reinforced with RSJs (Reinforced Steel Joists) to support the ceiling and vertical walls.

Dormer Design

Dormer conversions create very versatile rooms because of the additional headroom when compared with many loft conversions.

Internally, design ideas include greater use of vertical windows and walls. Externally, designs will be subject to planning permission and building regulations.

External design of roof extensions are controlled because of their visual impact, they are required to be within character of the house, which usually includes reproducing the house style and using sympathetic materials.

Dormer Plans

Dormers are subject to planning controls - always-requiring planning permission, and compliance with building regulations.

Regulations and controls exist to ensure dormers are built in the right place (protecting amenity and environment in the public interest), to the right size, layout, site and external appearance of your house.

Specific regulations cover dormer extensions and dormers (windows).

They need to be within character, so extensions and windows are constructed in a design and to a style that generally blends with the existing look and feel of your property.

Many Councils require 'they are not out of character with the ... area'.

Many dormers are only built on rear facing roof sections as there are fewer controls than for street facing windows.
