Most front doors open inwards, however if you are limited with internal space it is possible to get doors that open outwards.
Ultimately, the choice is yours and is dependent on what you need for your property.
The reason most front doors open inwards is for security. A door that opens outwards would normally have the hinge exposed on the outside of the building, which would make it accessible to anyone. With this in mind, it might not be possible to have the same choice of doors if you need them to open outwards, as not all designs will be able to have a hinge on the outside.
If you have limited space for an inward opening door, or need an outward opening door for accessibility reasons, please speak to your local installer and they will be able to provide you with helpful advice about your best options.
