In combination with rear dormers

One of the most common types of Loft Conversion we design is known as a "Hip to Gable Loft Conversion". For owners of detached, semi detached or end of terrace houses this type of Loft Conversion often represents the best option available due to the large amount of usable space that is created inside the Loft.

On this page we have the answers to a few of the most common questions we are asked about Hip to Gable Loft Conversions and a few sample Planning Issue Drawings for you to look at. If you are interested in having us draw up some plans for your Hip to Gable Loft Conversion please get in touch. Here's how it works:


As you can see in this image the front and rear facing roof pitches can be extended out, eliminating the third roof pitch or "hipped end" so that a triangular "gable end" is formed instead. Making this change will have the effect of increasing the area within the loft where it is possible to stand up. Adding a gable end like this is often crucial to the design of a loft conversion especially if  the existing "hipped end" happens to be on the same side of the house as the existing staircase. Ideally the new loft staircase would be located above the existing one because this reduces circulation space but if there is no standing space up in the loft above the existing staircase that arrangement doesn't usually work. For this reason adding a gable end can make all the difference to the deign of some loft conversions. To get even more usable space in the loft you also add a rear dormer like this;

Adding a rear dormer creates a much bigger internal space to work with. Standing space is usually more than doubled and this is extra standing space generally creates a space big enough that it can accommodate a bedroom with an en-suite and storage spaces as well as the new stairwell.

This is an example of a hipped roof such as you might find on a typical semi detached house. This particular roof consists of three pitches (sloped roof faces) but there could just as easily be four or more pitches if we were looking at a detached house. The loft space that exists within this roof will be of limited use when it comes to creating a room. There simply isn't enough space where you can stand up to form a decent sized room and to accommodate the space required for a stairwell. Most of the time the best (or perhaps only) solution is to change the shape of the roof by adding a gable end and a dormer. It works like this:

We have designed many hip to gable loft conversions down the years. Here are a few recent examples:

If you have a project in mind we'd love to hear from you so please get in touch.  We offer a comprehensive service which we think represents the best value for money available. You can read all about it here:


If you've already looked at our prices and want to get started the first step is to book a visit from one of our experienced design consultants. The consultant will take a look at the property and discuss the potential loft conversion with you. If the project is feasible and you are happy with what is suggested then our consultant will take a full site survey then and there so that we can move forward to getting some plans drawn up for you. If the project is not possible, or at least if it is not what you were hoping for then there is no further commitment. The survey isn't performed and we part company. There is no charge in that situation. We find this approach suits both parties as it avoids the need for return visits. 

To make an appointment you can either call the office on 020 3031 6628 or book online. It's easy.
