After a 26-year TV career visiting hundreds of homes, property guru Phil Spencer knows what makes a well-designed house. Now the Channel 4 presenter has revealed to the Daily Mail the design flaws that have left him reeling – and the popular trends he believes people are now turning away from. Teaming up with long-time friend Kirstie Allsopp, he has presented a number of property shows, with the most popular being Location, Location, Location and Love It Or List It. In Love It Or List It, they visit a person's home to help decide if they should make renovations to their space so it better suits their needs; or if they're better off selling up. Phil, who is also an ambassador for Wickes, says that while filming this show in particular, he has come across homes with the biggest design flaws.He said: 'We're going to a house that doesn't work for some reason, and the family can't decide what to do about it. And so we do see a lot of houses that are just badly laid out. Property guru Phil Spencer speaks exclusively to the Daily Mail about the design flaws in homes that have stayed with him during his 26 year TV career 'Particular things that are noticeable, that stick in my mind, are when toilets are off kitchens. How does that happen so often?'Other notable design flaws include long corridors which cause 'wasted space', and corridor designs with 'doors in the wrong place or doors that hang the wrong way', or 'doors opening on to themselves'. As interior trends move with the times, Phil said he has also noticed a change in the way people want their homes laid out. In particular, he said he has seen a reversal in a desire for open plan houses. The previous trend for 'opening things up' in Victorian buildings, to 'cope with modern lifestyles' is no longer as popular as it once was, says Phil.'Open plan was such a popular thing pre-Covid. But it's gone slightly the other way now, with more people working from home realising that being completely open plan can have its disadvantages.' Phil noted that open plan homes are slowly falling out of fashion as people work from home more - and therefore feel the need to separate their working space from the rest of their homeHe added: 'If somebody's opened up their kitchen through to their living room, and they're now working from home, and the kids come home from school - that's a disaster! So we are seeing some people closing space back up.'In addition to different layouts within the home, the property expert also previously revealed how a house's outside space might be affecting its selling potential. 'The garden is as important and as valuable as a room,' he said. 'And it needs to be treated as such. So, it does need to be looked after, it needs to be presented.'You walk into a garden that's full of dog poo, it's an immediate turn off. And I see it. It's such a basic "don't do that." Clean up after you go.'Phil added that the key is keeping your garden full of life: 'Personally, for me, a garden is about plants, greenery and nature.''I love a garden, it's super important to me. And when I was house hunting, when I'd arrive at the house, the first thing I wanted to do was look around the back. What does it look like? Are there any trees? What would we do? How easy will it be to look after?'He suggested a 'fussy' or overgrown garden may put off a prospective buyer because it requires a lot of maintenance. Similarly, extravagant water features, when not looked after properly, can end up looking mossy and dishevelled, and also turn off a potential buyer.As for the garden features he thinks can make a positive impact, Phil recommended investing in a water butt to save water (particularly in increasingly dry summers) and using things such as bird houses to encourage wildlife into the garden.
