Circumstances change over time, and the choices you make when you first move in do not have to determine how you use your home forever.
Layouts are designed to be flexible, so a bedroom can become a study, guest room or hobby space as your needs change. And if stairs become difficult in future, the ground floor has been designed to support single-level living.
Where future layout changes may be needed, these have been considered from the outset so they can be made without major alteration. It means you can choose the arrangement that suits you now, knowing your home has been designed to adapt with you.
