UK's most expensive homes
Brechin Castle in Angus, a snip at £3 million

While many aspiring homeowners are struggling to find somewhere affordable, the super-rich have been on a buying spree. According to independent analysts LonRes, last year they spent an unprecedented £11.6 billion on prime London property, and estate agency Knight Frank reports record sales of country houses costing £5 million plus. If money’s no object or you’re dreaming about what you could buy with a lottery win, here’s our pick of the priciest homes on the market across the UK.

1. Stuart House, Knightsbridge, London SW1, £35 million

At 11,855 square feet, this is the largest single house in the Royal Borough of Kensington and Chelsea for sale publicly as opposed to off-market (without being advertised and how many high value properties change hands). It’s in Cadogan Square, one of the capital’s most prestigious addresses, and a short stroll from Sloane Square, Harrods and Hyde Park. Grandly proportioned throughout, accommodation is spread over six levels with lift access, and includes six bedrooms, six bathrooms, five reception rooms, an indoor swimming pool and gym on the lower ground floor and a second floor roof terrace. Dozens of original features are intact, among them ornate stone and plasterwork wall and ceiling mouldings, sweeping staircases and oversized fireplaces. It's on the market with Rokstone.

2. Kensington, London W8, £23 million

This seven storey townhouse has been modernised and reconfigured to create the ultimate abode for a money’s-no-object buyer who loves keeping fit and entertaining. The basement houses a swimming pool, gym, treatment and steam rooms. A contemporary kitchen/breakfast room and separate dining room are at raised ground level, with a grand drawing room taking up the entire first floor. All six bedrooms have ensuite bathrooms, and thanks to extensive use of glass – including an atrium and partially glazed roof above the pool – the property is flooded with natural light. There’s also a lift, study and family room which leads out to a decked garden, and Kensington High Street and Kensington Gardens are round the corner. It's being sold by Strutt and Parker.

3. Harford Manor, Holyport, Berkshire, offers over £20 million

If you’re wondering why this 24,000 square foot modern mega-mansion looks familiar, that’s because it recently appeared on Britain’s Most Expensive Houses on Channel 4. The double height entrance hall gives you a taste of what’s to come, including a central galleria, an entertaining kitchen with a cantilevered island, a catering kitchen, sitting room, library, orangery, boot room, cinema and games room, gym, pool, a wine cellar with space for 1000 bottles, nine ensuite bedrooms and staff quarters. A roof terrace offers panoramic views towards Windsor Castle, and the house is surrounded by 40 acres of grounds with landscaped gardens, woodland, paddocks, stables, a helipad, and eight-car garage. It's on sale with Fine & Country.

4. Glen Usk, Llanhennock, Monmouthshire, £6.5 million

Unsurprisingly, the most expensive home for sale in Wales is a real stunner. Built in the 1820s in a symmetrical design typical of the Georgian era, Glen Usk has been sympathetically refurbished and overlooks the River Usk and the Ryder Cup golf course at Celtic Manor. On the ground floor, six palatial reception rooms open off a communal hall entered via a Tuscan-style colonnade. These feature soaring ceilings, full-height windows, carved marble fireplaces and decorative plasterwork, and the kitchen - which is bigger than an average one-bedroom flat - connects the house with an adjoining Grecian-inspired temple, added in about 1840 and containing a library with a minstrels gallery. Upstairs you’ll find eight bedrooms and seven bathrooms, it also has a playroom/gym, full-size snooker room, a wine cellar, a bar and a dance floor in the remodelled basement. Outbuildings, stables and two fully-renovated cottages are included, and there’s ample space to land a helicopter in the grounds. Fine & Country are the agents.

5. Brechin Castle, by Brechin, Angus, offers over £3 million

You get a lot for your money north of the border, as demonstrated by this huge and historic castle, lying in 70 acres of land on the east coast between Dundee and Aberdeen. It was constructed in the early 1700s, incorporating part of a 13th century fortress which once belonged to Scottish kings, and includes eight reception rooms, 16 bedrooms, 10 bathrooms, original wooden panelling, columns and a staircase with striking ironwork balustrades that were installed in 1659. The garden, regarded as one of the finest in private hands in Scotland, features a walled area linked to the castle by woodland paths bordered by banks of azaleas and rhododendrons that are a riot of colour in springtime, and the estate also comprises two gate lodges, three further cottages, stables and fishing rights on the river south Esk. If all this isn’t enough, a further 197 acres are available separately. Interested? Give Savills a call.
