Credenza: nobody knows what this is. A type of fish soup?
Curated: the home as the heavily-edited gallery exhibition of the self. If you expect your friends to pretend to admire it, serve wine and cheese at the opening.
Fitted kitchen: old industry joke. If it's fitted, it won't. You haven't felt this rubbish about sizing since the Topshop dressing rooms.
Fixture: a terrifying word to hear from a tradie, as in: "I've fixture toilet," when - as far as you were aware - it wasn't broken.
Flashing: what the plumber's heavy toolbelt is responsible for.
Flock wallpaper: already over. Get the flock out of here.
Greige: grey-beige, the most popular interior colour because it matches all your possessions once the plastering dust settles on them permanently.
Incandescent: what you'll be when you get the final bill.
Hardware: something the doors need, so called because it costs the same as a new computer.
Minimalism: Great if you like clean lines and a slight echo. You'll need a storage unit for your knick-knacks because the designer threw up a little when you used the word knick-knacks.
Moulding: either ornate plasterwork on your ceiling or what they find when they open up the bathroom gib. Confusingly, your moulding can be moulding.
Paint sample chart: a torture device. None of those paint colours actually exist; Half Tea is the only one they really make because that's what you'll choose when it all gets too overwhelming.
Open plan: the ongoing changes to the supposedly approved design. Requires an Open Wallet.
Shabby chic: the furniture, the rugs, the walls and the inhabitants are distressed.
Splashback: what the shower does since you went for the waterfall showerhead.
Suite: what you say with deep satisfaction when you hear the unfixable cracking sound your old bathroom units make hitting the skip.
Test pot: what you'll be tempted to do to make the renovation process more enjoyable.
Throw pillow: the safest way to express mid-project frustration.
Waste: what you'll feel about the project manager's fee when you realise you haven't seen him in weeks.
Vanity unit: an interior designer.
