New: The Complete Invisidoor Set

LL Company are excited to launch the complete Invisidoor Set which includes the Invisidoor Hinge Kit and NEW Secret Bookcase Bookpull Latches! Now you can buy all the products you need to create a secret entrance to your home office, cinema..... or underground bunker? 

Whether you're creating The Volcano Lair from You Only Live Twice or Kanaga's Lair in the green grotto caves in Live & Let Die.... you'll need a secret door and a hidden book pull (and maybe a security guard called Nik Nak) to conceal your evil mission. 

Since introducing the uniquely designed Invisidoor Hinge Kit, which has been very popular, we have had so many requests for other unique bookcase accessories. We sourced the Secret Book Latches from a high quality supplier in the States and are thrilled to be able to offer it as part of our unique and growing product range.

Other great ways to incorporate a Secret Door 

Dressing rooms, bootrooms (or shoe rooms!) pantries, children's playrooms, artist studio, quiet office spaces or reading rooms, yoga studios, bedrooms and so much more! 

Secret Book Latches

If you’re looking for a completely original interiors’ve just found it! Both fun and stylish, our new Secret Book Latches are pretending to be regular books on a bookshelf....until you pull them. This clever mechanism allows the book to open the door by simply rocking the door towards you to release the door catch. For gadget lovers, this is a winner and will remain completely undetected until you are ready to reveal the secret room beyond!  

Supplied as a complete kit which includes a black leather bound book, there is some easy assembly involved before you can play with your new product!
