Types of windows for your loft conversion

Every loft conversion is different. You can decide to simply refurbish the space you already have waiting for you, or completely overhaul your loft along with your roof structure in order to gain an entire additional floor in your home. Whatever your choice may be, one of the most important factors you should consider when planning a loft conversion are the windows. Here are some of the most prominent types of windows used for loft conversions.

Dormer windows

This is the most commonly type of window found in loft conversions in the UK, as dormer conversions are the most popular type of conversion around. The main features of this type of window are a raised box (dormer) that is cut into the original sloping roof of the home. This helps increase the headroom in the loft, making it a perfect choice for lofts with low-hanging ceilings. Dormer windows usually do not require any form of planning permission, though some restrictions may occur, for example requiring the former windows to be rear-facing or constructed from materials that match the rest of your home.


Whether you call them rooflights or skylights, this type of window is a fantastic, modern option that can work with any type of roof, whether it’s pitched or flat. Whichever type you have, however, rooflights are the best choice is you really want to flood your loft with light. Since they point directly to the sky, natural light has no problem coming in and making your loft space brighter than ever. Keep in mind, however, that that also means the sky is pretty much the only thing you’ll be able to see through them, so don’t get them if a view is what you want. Since these windows do not protrude outside or inside, they won’t change the height of your ceiling in any way. An extreme version of this that you might want to consider is a roof lantern. Basically, you replace parts of your roof with a glass box, creating a greenhouse-like aesthetic, maximising the amount of daylight coming in. How’s that for a view?

Gable-end windows

The gable is the triangular part of your wall that connects to your roof. As the name suggests, gable-end windows are installed in this portion for great effect. If you get all the right permissions, you can even get a window that will go all the way from the floor to the ceiling for a fantastic, panoramic view.
