If you are considering carrying out a major property improvement, it is essential that you consider all of your options before proceeding with a final design. You may, for example, have thought about extending over an existing ground floor structure to create a bedroom without realizing you have fantastic potential to convert your loft at a lower cost. You must be clear about why you want to extend your home and what the room or rooms will be used for. You will need to consider furniture arrangements at an early stage which may well impact on the overall room sizes you require.
