How much does a small apartment renovation cost? An honest per-m² breakdown

Before we talk numbers, you have to understand that the price of a renovation is never just tiles and paint. It's made of several layers you don't see: demolition and waste removal, preparing the substrate, the wet work and plumbing, the electrics, and only at the end the finish you pick out at the shop.

The easiest part to price is the finish, because it has a price on the shelf. The part that surprises people is what's underneath: old pipework that needs replacing, electrics that don't handle today's load, a floor that needs leveling, or damp that shows up the moment a wall is opened. Those are the things that move the final number, and they're what you can't see from a photo.

That's why we work with a detailed BOQ that breaks every item out separately. That way you see what you're paying for, you can drop or add items to fit the budget, and you don't get one round number that can't be unpacked.

The biggest difference in price isn't the size of the apartment but the depth of the work. The same 60 m² apartment can cost one figure if you only refresh it, and double or more if you go down to the concrete and replace the infrastructure. It's worth knowing which level you're at before you compare quotes.

A cosmetic refresh is the light level: paint, swapping fixtures without moving pipework, sometimes tiling over existing tile, replacing interior doors. You don't touch the infrastructure, so it's also the fastest and cheapest. It suits an apartment in reasonable shape that just needs freshening up.

A mid-level renovation is the most common in small apartments: replacing the flooring, redoing one or two bathrooms with full waterproofing, updating part of the plumbing and electrics, maybe a small layout change. This is where real wet work starts, which pushes the price up but also extends how long the renovation lasts.

A full renovation goes down to the concrete: tearing out all the flooring and cladding, fully replacing the water and waste pipes, a new electrical board and points, re-waterproofing all the wet spaces, and sometimes a layout change. It's the most expensive level per m², but it's also the one that leaves an apartment you won't need to touch again for years.

Here are rough per-m² cost ranges by depth, so you can build a first estimate yourself. Note: every figure here is for guidance only, based on typical work in central Israel, and is not a quote. The real number for your apartment is set only at a site visit, after we see the infrastructure.

To translate this into a whole apartment, multiply the per-m² range by the apartment's area, then add the one-off items that don't divide neatly per m², like a full bathroom or a new electrical board. A small apartment tends to come out more expensive per m² than a large one, because the fixed jobs, the bathroom and the kitchen, are spread over fewer meters.

Once you have a rough range, it's worth understanding what pushes it either way. Most of these things don't show up in a photo, which is why we insist on a site visit before any number.

What raises it: old pipework that needs a full replacement, an electrical board that can't handle the load and needs updating, an uneven floor that has to be leveled before tiling, existing damp that surfaces when a wall is opened, a layout change that means knocking down walls, and difficult access to an apartment on a high floor with no lift, which raises the cost of waste removal and carrying materials up.

What lowers it: keeping the existing layout without moving walls, tiling over existing tile when the condition allows, leaving the pipework and points where they are, and choosing a finish in the reasonable range instead of a luxury item. Every item you can leave as-is saves on both labor and material.

The finish level is a variable on its own. The same tiling work can cost very differently depending on the tile you pick out at the shop, and that part is fully in your control. We always separate labor cost from material cost in the BOQ, so you can play with the finish without it muddying the labor price.

Beyond the work itself, there are a few items that always appear and that people tend to forget when they build a budget. It's worth giving them room up front so you don't get stuck midway.

Construction waste removal is a real line item, especially in a full renovation that generates a lot of demolition. In a shared building you also have to account for protecting the stairwell and common areas. An apartment on a high floor with no lift raises both the removal cost and the cost of carrying materials up.

Fixtures, taps, light fittings and electrical points are items you choose and buy, so they vary a lot by taste and budget. In the BOQ we separate the installation cost from the item cost, so you know how much of the price is labor and how much is your purchase.

It's also worth leaving a small reserve in the budget for infrastructure surprises, mainly in older apartments. We try to expose as much as possible at the visit, but some things only show up when a wall is opened, and it's better to start a renovation with a cushion rather than on the edge.

The difference between a good quote and a bad one isn't the number at the bottom but how detailed it is. A quote that sums everything up in one line, apartment renovation, an amount, tells you very little and leaves a lot of room for surprises midway.

A good quote breaks the work into items: demolition and removal, plumbing, electrics, waterproofing, tiling and cladding, paint, finish. Each item has a quantity and a price, with labor cost separated from the cost of the material you buy. That way you see what you're paying for, you can compare quotes item by item, and drop or add to fit the budget.

It's also worth checking what isn't written: whether waste removal is included, whether there's a written warranty on wet work, and what happens if an infrastructure surprise turns up midway. A transparent quote addresses these up front instead of leaving them to an argument on site.

You can get a rough range on the phone, and that's fine for a first feasibility check. But a real price, one we can stand behind, requires seeing the apartment: the state of the plumbing and electrics, how level the floor is, the condition of the wet walls, and the access to the apartment.

A site visit takes us an hour and it's what separates a guess from a quote. On the visit we measure, open test points where needed, and understand what's hiding behind the plaster before we commit to a number. That way the quote you get is realistic, with fewer surprises midway through the renovation.

After the visit you get a detailed BOQ with clear price ranges, a written warranty on wet work, and a fixed crew that sees the apartment through from demolition to handover. That's the basis that lets us stand behind the price, rather than just throwing out a number on the phone.
