For added storage space and secure parking have you thought of a garage?
These can be designed any size and shape to suit your requirements. Adding value to your property whilst making savings on car insurance.
Alternatively, if you already have a garage have you thought of converting it to a more usable space for the modern family? Perhaps an extra lounge, play area, bedroom or utility room.
Many people have converted their previously under used garage to a home office, a potentially tax deductible approach to working from home, a cost effective way of adding value to the property.
