The true cost of a room: how to budget in bands, not guesses

Ask the internet what a living room costs and you'll get answers from £300 to £30,000. They are all correct, and none of them useful. Room budgets only become manageable when you stop chasing a single number and start thinking in bands.

A band is a deliberate choice about the role a room plays in your life and your finances. Once the band is set, the rest of the decisions have a frame.

The five bands

We use five, and they map to how people actually renovate: under £500 (a refresh with paint, textiles and one hero piece), £501–£5,000 (a proper makeover without structural work), £5,001–£14,000 (new flooring, good furniture, perhaps fitted storage), £14,001–£45,000 (a transformed room with kitchen work, bespoke joinery and trades throughout), and £45,000+ (structural change, extensions, the works).

None of these is a judgement. A £400 bedroom done with intent beats a £14,000 one done by drift, every single time.

Big pieces set the ceiling

Within a band, not all pounds are equal. A useful rule: the big-ticket item, such as the sofa, bed or dining table, should sit around a sixth of the room's total budget. Discretionary pieces, such as lamps, cushions and art, nearer a fifteenth. When the big piece is right for the band, everything downstream stays coherent.

This is also where overspend hides. Blow the ceiling on the sofa and you'll spend the next six months trying to make a £200 rug behave in a £5,000 room. Soft ceilings keep the room honest.

Expect the 15% you didn't plan

Every honest budget carries a contingency. 10–15% is the convention, and it's the first thing to protect and the last thing to spend. In older homes assume you'll meet something unexpected the moment a wall comes off. The contingency isn't pessimism; it's the difference between a surprise and a crisis.

Keep the running total visible as you buy, not at the end. A room that drifts £40 at a time is a room that ends £1,000 over.

Let the budget learn

Your first band choice is a hypothesis. As you save pieces to a room and watch what you actually gravitate towards, the right band reveals itself, sometimes higher (you kept falling for the £2,000 sofa), sometimes lower (the high street dupe genuinely made you happier).

That's the approach we take in Renosense: bands are soft, room-aware, and recalibrate as your taste emerges. The budget serves the room, never the other way round.
