A full mid-range renovation typically runs somewhere in the range of ₪6,000–₪12,000 per square meter, depending on demolition scope, finish quality, and how much of the building's systems (electrical, plumbing) need upgrading. For a 90 square meter apartment, that puts a full renovation roughly between ₪270,000 and ₪450,000 — though high-end finishes, structural work, or full mechanical upgrades (smart-home wiring, underfloor heating, expanded electrical capacity) can push that higher.
A few things move the number more than people expect:
Full demolition vs. partial — stripping an apartment back to its shell costs meaningfully more than working around existing walls and layouts.
Building age — older Jerusalem apartments often have outdated electrical and plumbing that needs full replacement, not just cosmetic work, which owners frequently underestimate when budgeting from a "surface-level" quote.
Import and material choices — imported fixtures, custom aluminum work, and high-end finishes carry a real premium over locally sourced equivalents.
The single biggest cost risk isn't the renovation itself — it's mid-project change orders. Once demolition has started, a contractor knows you can't easily get a second quote, and pricing on additional work tends to reflect that. The owners who avoid this are the ones who lock in competitive bids and contract terms before work begins, not partway through.
If you're budgeting for a renovation, get a scope-specific estimate rather than relying on a per-square-meter average — apartment layout, building age, and finish level swing the real number more than any general guide can capture.
