[LONDON]  For anyone with one eye on a sweet penthouse in London, every day is like Black Friday.

Prices for some jewels of London real estate are falling fast, with more coming on the market even as fears of a market crash and uncertainty weigh on demand. Purchasers are asking for reductions of 15 per cent or more when they bid for homes, and penthouses are no exception, according to Hannah Taylor, an assistant sales manager at broker MyLondonHome.

Here are five penthouses in the city that have had their asking prices cut by at least 20 per cent:
