Door Question

[Reinder W]

I am building a sound studio on the top floor of an office building and because it will be a "room within a room" design (for soundproofing), the inner dimensions will shrink a fair bit. So, Is there a minimum height regulation for the doors? I have space for a 1940mm high door. Is that OK?

Whilst UK standard doors are generally 6ft 6in tall (1981mm) we do sometimes fit 6ft 3in (1905mm). However, they are not off the shelf doors and we generally need to have them made or cut down flush fire door blanks and relip the bottoms
