Our office is quite good, the features I like are:
An expressing room for breastfeeding mother room. This is lockable, and has a comfy chair, a sink, a fridge with lockable compartments, and few non-refrigerated lockers. They don’t have that many women who need to use it, so you get a locker key from reception and keep it for a few months or however long until you’re done with expressing.
Various types of rooms, large meeting rooms, smaller ones with either two or four chairs, some “phone booths” that don’t have phones in but are that sort of size with a bar stool and a small ledge so you can take you laptop in and have calls in there. The phone booths and some meetings rooms aren’t bookable, you just nip in, others you can book if you know in advance you’ll need them. All these areas have ample charging points and the meeting rooms have a screen and a thingy for dialling in to calls.
We also have some different seating arrangements, so large desks with multiple chairs and some second screens for people to plug laptops into, big round tables for people who are working collaboratively that day (no second screens on these to block conversation), smaller desks in little booths where you’d work alone.
We have a lot of lockers, everyone is assigned one, so as we hot desk you can leave stuff in the office.
Somewhere there is a prayer room I think. Don’t know what the set up with that is.
What we are distinctly lacking is second screens, more desks could do with these, and they could be more reliable. Some are broken.
So I guess the features I like are all around flexibility, how do you want/need to work that day - in a group, or do you need to be somewhere quiet to concentrate, do you need to book a meeting room, or are you just after a quick private chat.
