Fancy buying a house that stands out?
The standard advice is that, for a house to sell, it should be as neutral and bland as possible. However, many of us prefer something a bit different.
We've rounded up our top 10 quirky properties currently on the market.
The gun emplacement
The uniqueness of this property starts with its address: Number 1, The Thames. Sited on a spit of land on the Isle of Grain, near Sheerness, it is only accessible at low tide. Similar to a Martello tower, it's described as bomb-proof but is in need of complete remodelling: agents River Homes say it could become anything from a private home to a nightclub. It's priced at £500,000.
The castle
The description on Zoopla is "three-bed house" - but this is selling the property short, to say the least. Kilmartin Castle is a semi-fortified, late 16th-century castle in Argyll, boasting three towers and two stone spiral staircases. It does, though, boast all the comforts of the present day, with three ensuite bathrooms - one of which is circular. It's for sale with Knight Frank for offers over £375,000.
The tiny one
£275,000 doesn't buy you much in Barnsbury, Islington - just what may be the capital's smallest house. It has just 188 square feet of living space, with the bed on a mezzanine accessed by steps from the kitchen worktop, and a loo inside the shower. Agent Winkworth suggests it would make a great pied-a-terre.
The water tower
Prospective buyers will be relieved to discover that this four-bed property in Lutterworth has a lift: it's set over five floors. The fourth consists of a high-ceilinged sitting room with a 360-degree balcony running all the way round. Outside it has two acres of gardens, including woodland and a disused quarry. It's for sale with Strutt & Parker for £549,950.
The hobbit house
This "earth sheltered" eco house doesn't exist yet: purchasers will be paying £400,000 for a set of plans and a piece of hillside near Canterbury. When completed, though, the house should be near-invisible from any distance, thanks to the way it's built in to its hillside site.
"Conceived to take full advantage of the hillside site without interfering with either contour of the hill or the view from below, the design has been cleverly planned to allow maximum light into the main living and entertaining spaces," say agents Strutt & Parker.
The lightkeeper's house
Attached to a decomissioned lighthouse near Portpatrick on Scotland's west coast, Killantringan Light Keepers House has the living areas on the first floor, to take advantage of the spectacular views.
Perfect for wildlife lovers, the area is home to pine martens, golden eagle, red deer, red squirrels and natterjack toads. Agent Knight Frank says the vendor is looking for offers over £485,000.
The church
This former church, near Leeds, retains its stained glass windows, marble columns and statues of saints. It has a grand hall measuring 28 feet by 21, several further reception rooms and four bedrooms, three with ensuites. Even the clock tower has been restored and is in full working order - meaning the buyer need never sleep through the alarm.
The log cabin
Right on the banks of Loch Lomond, this three-bedroomed log cabin has far reaching views and feels as if it's in the middle of nowhere. But it isn't by any means basic: it has both central heating and air conditioning, as well as Sky TV and Wifi. It costs just £30,000, through agents Trinity Irvine.
The high-up one
St George Wharf Tower, also known as the Vauxhall Tower, is the tallest residential-only building in the UK, at 181 metres high. This two-bedroom flat, for sale through I Am The Agent, is on the second-highest level and boasts 2,029 square feet of space. The building houses a residents' spa, swimming pool and gym, as well as a business centre and cinema room.
The houseboat
For sale through agent Foxtons for just under £210,000, this charming boat is moored right next to Kingston Bridge. It has a bright reception room with bi-fold doors to the deck, a double bedroom with fitted wardrobes and a kitchen and bathroom. There's even a jacuzzi hidden under the deck.
