Add a bedroom to give more value to your house
If you are planning on selling your property consider the possibility of adding an extra bedroom to add re-sale value to it. A four bedroom house will have more value than a three bedroom house. Thereby it is possible to earn double or more than the amount you invest in the home improvement when selling it.
You can make the addition by doing a loft conversion or by doing an extension, depending on the amount of space you have. You could also convert an existing space in the house such a home office in you an additional bedroom.
More value to the property will be added by extending the floor space rather than a conversion. To maximize the benefit of the renovation make sure you spend no more than 10% of the value of the property on the extension.
Also keep in mind the locality of the house. Adding two bedrooms to a house in a street which has two bedroom houses will make hard to sell.
It is better to have a little garden space rather than adding too many rooms. Too many additions will make it out of scale and may require the addition of another bathroom as well.
