We get this question constantly from families with a home that's 20–40 years old: is it worth renovating, or should we just rebuild? The honest answer depends less on the home's age and more on three specific things.
First, the foundation and structural frame. If the existing foundation is sound and the structural columns show no cracking or corrosion, renovation is almost always the more economical route — you're preserving the most expensive part of the building. Second, floor-to-ceiling height and layout flexibility: older homes built to older norms sometimes can't accommodate a modern layout without expensive structural changes. Third, the scope of what you actually want changed — a kitchen and bathroom upgrade is a straightforward renovation; adding a full additional floor on an old foundation needs a proper structural assessment first.
Our approach on every renovation enquiry is the same: a structural engineer inspects the existing building before we quote anything. That inspection tells you honestly whether you're looking at a renovation, a renovation with foundation reinforcement, or a rebuild — and it costs far less than discovering the answer halfway through construction.
