Renovation or Rebuild? Deciding in Mallorca

Key takeaways

  • Settle what the plot allows before comparing any prices. It can change the answer completely.
  • A rebuild removes the unknowns that make old buildings expensive, and it removes some of the building too.
  • Demolition is never free, and it is frequently left out of the comparison.
  • Keeping the shell and rebuilding inside is a third option people forget.

The question usually arrives at the end of a renovation conversation rather than the start of one. Somebody gets the work priced on an older property, the number is larger than expected, and replacing the building starts to look like the sensible alternative. Sometimes it is. The comparison is just rarely as simple as the two figures.

Settle the plot question first

What may be built on a plot now is not always what is already standing on it. A building that predates the current arrangements may have floor area, a height or a position close to a boundary that a replacement would not be permitted to repeat. Demolishing it can therefore cost you part of the property permanently, and no price comparison that ignores this means anything.

This is established by a technical team for your specific plot. It is not expensive, it is not slow relative to the decision it informs, and it is the single most useful thing to buy before choosing a direction.

The third option most people miss

Keeping the structure and rebuilding everything inside it. On a sound old building this is frequently the best value available: the shell has already proved it stands up, the walls are usually generous, and rearranging within them avoids almost everything that makes new construction slow and expensive. It is what complete refurbishment means, and it sits between the two headline options in both cost and disruption.

How to actually compare

  • Establish what the plot allows. In writing, before anything else.
  • Get the existing structure surveyed, so the renovation price is real rather than cautious.
  • Price the renovation and the rebuild against the same finished result, not against different ones.
  • Include demolition and disposal in the rebuild figure.
  • Include the technical and design work in both, since both need it.
  • Ask what each route does to the programme, not only to the total.
  • Ask one company to price the refurbishment option as well, as a third number.

If the plot is empty already, or the existing building genuinely has nothing worth keeping, new build covers what that route involves. If you have not bought yet, this belongs in the questions asked before completion, when the answer can still change what you offer.

Is rebuilding usually cheaper?

Sometimes, and it depends on the property and on the plot rather than on any rule. A rebuild removes the unknowns that make old buildings expensive to renovate, and it also removes whatever the old building had that could not be built again.

How do I find out what the plot allows?

A technical team establishes it for your specific plot. It is the first thing worth paying for, because everything after it depends on the answer and nothing before it is worth much.

Can I keep the facade and rebuild behind it?

It is done, and it is structural work rather than a compromise between the two options. Whether it is possible and whether it is worth it are separate questions and both are established on the property.

What if the building has real character?

Then it is worth pricing the refurbishment route properly before deciding, because character is one of the few things a rebuild genuinely cannot recover. Rooms of old proportion cannot be built new at any sensible cost.
