'm not sure how much notice to take of it tho because it calls Collin McAllister and Justin Ryan "Two property experts" LOL
here is the basic gist of the article ( my favourite is the garden gnome! ) :
The following is a list of the top twelve 'design crimes' and the amount it could knock off the value of your home:
- Dirty or paint spattered light switches - £3,000
Grubby light switches imply that the wiring in the house is old and will need to be replaced. Buyers will reduce the offer price as a result.
- Stone cladding or pebbledash - £3,000
Take one look at Coronation Street and you'll see exactly why people have gone off stone cladding. Vera Duckworth has much to answer for.
- Modern UPVC windows in an old or period property - £10,000
Bidders adjust their offers drastically, either as compensation to put up with them or as means of paying for re instatement of proper period windows.
- Overcrowding rooms with furniture - £2,000
Too much furniture and clutter makes a room seem smaller than it really is.
- Gnomes in the garden - £500
They're tacky and buyers will think you're strange and therefore your house must be too.
- Dead or dying pot plants on show - £500
This suggests a badly lit or sick house.
- Gloomy interior lighting - £500
Buyers may get the impression that there's not much natural light. It's also depressing.
- Extension or porch which is not in keeping or is badly built - £2,000 (minimum)
Ugly add-ons are a major detraction particularly if buyers think they'll have to knock down and rebuild.
- Patterned or brightly coloured carpets - £2,500
Unless the buyer also likes loud swirly carpets, they're going to be thinking about the cost of replacing them.
- Carpet in the kitchen or bathroom - £1,300
It's unhygienic and could be hiding dirt, damp and mould.
- Walls painted in bold or clashing colours - £1,000
Unless the buyers like your colour choices, they're going to be looking at repainting.
- Lime scale around the shower or bath - £500
It suggests a general lack of hygiene or cleanliness. Most people don't like grubby houses.
