There are many ways people are looking to improve properties at the moment from double glazing, installing bifold doors, removing internal walls to create a more open living environment and general DIY and decorating. The reason seems to be the slump in the economy, which does initially seem a strange concept, however, think of it this way:
During a recession, house prices are lower and it's more difficult to get a mortgage, therefore people are less inclined to move house, this means even for the households who are unaffected, there are far less properties available for them to move into, so they tend to extend or improve what they already have.
Whilst building and extension can add significant value to a property, it's also very disruptive and costly. I know this first hand, as when I moved we had the back of the house extended and moved the kitchen into the new bit, leaving a nice space to open up as a dining room, however, this meant walls coming down, walls going up, plasterers, electricians, plumbers and double glazing fitters, all in all total disruption for a few months. This was of course made more difficult by kids and dogs running through what was the muddy building site at the back of the house.
So bearing this in mind people are starting to opt for less intrusive home improvements, the type of thing which improves the value of a property, but also enhances their lifestyle, thinks like big outward openings on the property which look down the garden, with multislide or bifolding doors, which can be opened up in nice weather to almost make the room become part of the garden.
Multislide doors are the ones which slide back on themselves and leave a few thicknesses of glass at each end, while bifold doors are the ones which fold up on themselves and can leave the opening completely clear of glazing when fully folded back. They come in a wide range of glazing finishes and can have UPVC, wood or aluminium frames, so can be designed to fit in with the existing architecture of the property. They are usually also made to order, so can be fitted in pretty much any opening.
Of course there is always some disruption, as a large section of your wall will need to come down to fit the doors and an RSJ will probably need to be fitted to support the wall above. But all that said, even considering the time needed for building control to come in and inspect the work, it should all be done and dusted inside a week and you could be redecorating around your new sliding or bifold doors by the weekend.
