Now’s the time to make the most of the space you have in your existing home – and converting the loft is the best way to do it. At its most basic, a loft conversion can be a quiet place to set up your Hornby model railway, with a flip-down ladder for access and simple Velux windows. But a temporary staircase means it won’t count as extra living space when you come to sell, so generally it’s a mistake to do it on the cheap. Getting a specialist company or an architect on board will give you the best end result, whether you want the space to flow seamlessly on from the rest of the house or you just want to make a statement with a light-filled studio.

Location, Location, Location’s Phil Spencer’s number 1 way to add value to your home:

Go for a loft conversion

The easiest way to get an extra bedroom and bathroom. Not particularly disruptive, either, as most of the work can be done from outside. The key thing is to make sure access to the loft is easy and that the conversion fits the rest of the house, rather than looking grafted on. You will have to strengthen the floor joists, which will raise the floor level, so make sure you leave yourself with sufficient ceiling height to stand up in. Converting your loft usually costs around £20,000 and you can add £40,000 value to your house. I am always wary of quoting figures, but for the purposes of this article, I am using a survey of 110 estate agents, carried out by mortgage lender GE Money, which concluded that a loft conversion adds an average 12.5 per cent to the selling price.
