Everyone's tastes are different and we all have to make style choices when it comes to clothes, furniture, electrical appliances and cars. Therefore, surely when we make the biggest purchase of our lives we should get a choice?
However, this is often not the case even when buying an expensive new house as the design is limited by what the developer produces and planning regulations whilst the kitchen and bathroom specifications are at best chosen from a list.
A conversion or renovation can provide the skeleton of your self-designed dream home but the new build is the self builder’s ideal choice when they wish a blank canvas.
You could design your own layout yourself but it's probably best to get help from a builder or architect for regulations and practicality. There are books available to provide ideas that can be customised to suit the individual’s needs.
