DOOR FEATURES & OPTIONS
Rest assured, no matter which material you choose,
you’re getting a door built with an authentic style.
Material Options
A steel door is your best bet if security and durability are top priorities. Steel units are more robust than wood or fibreglass doors, and they won't crack or warp.
Locks
Our doors also come with a choice of various multipoint locking systems as standard. We can also integrate biometric, app-based or motorised access solutions upon request.
Iromongery
Ironmongery comes in a range of beautiful finishes, modern or traditional designs, sizes and materials, so we can perfectly match and style your door furniture to your door with refinement and luxury, whether it’s for a residential or commercial application.
Design Options
A wide range of customisable design options mean we can copy aspects of an existing door to match an original design, come up with something completely new and bespoke, or replicate on a like-for-like basis to ensure compliance with even the most strict heritage and conservation requirements.
