Regardless of your profession – or even if your home office is mainly for managing family life – you’re very likely to need a desk.
The size of that desk needs to reflect the tasks at hand but also the size of the space: small office designs can include a desktop that folds out from the wall or has an extension that slides out.
Building in bespoke home office desks or a computer desk can often make the most of a limited area (so perhaps under the stairs if you need somewhere to gather the detritus of family or school life).
If you are worried about being too sedentary, standing desks are increasingly popular. They allow you to flip between, sit/stand working and have adjustable height options (as do lots of the best modern office furniture).
But if you have a yearning for something more traditional, great bargains are available from auctions for something with gravitas (these tend to need more space) like a large leather-topped writing desk.
Or pick up a classic L-shaped or corner desk with some modernist chic, so two can work on it at once.
