Minimum Ceiling Height in an Office

Apologies in advance if I’ve posted this in the wrong forum. I can see there have been some previous threads on minimum ceiling heights in residential buildings but I wanted to ask if there is a legal minimum height for ceilings in offices?

A web search seems to suggest either 2400mm or 2134mm (7ft) but I’m not sure if these are just guidelines and if they apply in Ireland.

I’ve been advised by my employer that they intend to refurbish a storage room for use as a office and the ceiling seems really low. I haven’t had a chance to measure it yet but it’s certainly much lower than 2400mm.

HSA Regs should answer most of your questions.

Should be 2.40m. See Technical Guidance Document F here. Have a read from about page 27 onwards. It should confirm it there.

Thanks for that answer. I read through that document and I don’t see 2.4m mentioned. In terms of ventilation this room has an external door and a small window. It doesn’t have a connecting door to the rest of the building, nor as far as I know, any vent. The window can be opened so I suppose that will count as sufficient ventilation? This might be too specific a question but is there a minimum size a room needs to be for four people to work in? I saw a figure for the UK of 11m3 per person.
