Some of the greatest moments in TV happen on the Antiques Roadshow when lucky owners get the surprise news that their item is worth a small fortune.

We’d all love to be in that position – and I’m sure that like me, you’ve occasionally looked at your possessions to see if a valuable find might be lurking.

But all antiques have to start somewhere. And by choosing key pieces carefully now, you could be laying down the heritage pieces of the future.

There are a number of things you should look for when sourcing beautiful items for your home that may turn out to be an investment.

Rarity is always an indicator that something may gain value as it ages, so individual pieces are a sound purchase. Take Ercol’s Blotch Studio Couch, which was designed in collaboration with the renowned Glasgow-based fabric and wallpaper studio Timorous Beasties.

Ercol is a design classic from the word go – the Studio Couch was originally conceived by founder Lucian Ercolani in the Fifties. But now it’s been brought exquisitely up to date by Timorous Beasties’ fabric.

Each fabric swatch is printed to order featuring their dashing Omni Splatt and Thunder Blotch designs, which means each piece is unique. Can you hear future Antiques Roadshow tills jingling gently?

Another unique piece is the Pashtun Chair, which not only has individuality but also heritage. The chair, made by British craftsmen, is upholstered in re-worked vintage Suzani throws hand-embroidered with words and pictures celebrating village life.

The throws – discovered by chance in Paris – are works of art in their own right, and bestow on the chairs a charmingly timeless appeal.

There are other pieces still available which – like the Ercol studio couch – were instant classics on their arrival and add long-lasting glamour to our rooms.

The Barcelona Chair is a fine example of this. Originally designed by Mies van de Rohe in 1929 – yes, that long ago! – it retains its almost futuristic good looks and works well with a wide range of decors.

Strong shape is often the key factor in determining whether something will continue to gain value down the years, and I always point to the Kartell Bookworm as a design piece that will always hold its interest.

Designed by an artist using a great company’s technology, this curvy yet sturdy wall-hung PVC bookcase can assume any shape you fancy – so it adds your own creativity to its appeal.

Sometimes, though, a classic in the making already looks like an antique. I adore Timothy Oulton’s crystal floor lamp, so delicate when compared to his chunky leather and wood furniture.

In creating this salute to the traditional crystal chandeliers of the 18th century, the designer employs the best, traditional methods of chandelier production for his collection.

It doesn’t get better than that, because – in the end – there’s one overarching thing that defines all pieces that will become an investment for the future.

So when you’re picking out a future heirloom, let quality be your guide and you can’t go wrong. Future generations will thank you.
