The end of terrace conversion has 40 cubic metres to work with rather than the 50 cubic meters available to the semi detached property. Because of this it can be a challenge to get the conversion fully extended particularly if you have an hip end roof, which slopes in, as we have to end this as well as adding a rear dormer extension, so the 40 cubic metres is stretched to it's limit.
The plans shown here in the drawing are of an end of terrace hip to gable conversion. You will see that the dormer is set in from the sides and the rear. Even so a full double bedroom was achieved with a shower room.
