Starting a reforma integral casa 120 metros cuadrados is both exciting and, let's be honest, a bit terrifying when you look at the potential costs. A 120-square-meter home is really that "sweet spot" for many families—it's big enough to breathe but small enough that every decision counts. If you're living in an older flat or house of this size, you've probably noticed that the layout feels a bit cramped? Maybe you have way too many hallways and tiny rooms that don't serve a purpose.
Modernizing a space of this size isn't just about picking out pretty tiles. It's about rethinking how you move through your home. In this article, we're going to dive into what actually happens during a full renovation, how to prioritize your budget, and how to make sure those 120 square meters feel like 200 by the time the dust settles.
Rethinking the layout: The death of the hallway
Most older homes around the 120m² mark suffer from what I call "hallway syndrome." Back in the day, houses were built with a lot of separate, closed-off rooms. You'd have a long, dark corridor with five or six doors leading off it. If you're doing a reforma integral casa 120 metros cuadrados, the first thing you should do is look at a floor plan and see how much of your footprint is being "eaten" by those corridors.
By knocking down a few non-load-bearing walls, you can create an open-concept living area that combines the kitchen, dining, and living room. This doesn't just make the house look bigger; it makes it more social. You can be prep-cooking dinner while still chatting with people on the sofa. For a 120m² house, this usually allows for a massive "day zone" while still keeping three solid bedrooms and two bathrooms tucked away in a quieter "night zone."
Where does the money go?
Let's talk about the elephant in the room: the budget. People often ask what a renovation like this costs, and the answer is usually "it depends," which I know is a frustrating answer. However, when you're renovating 120 square meters, you're looking at a significant investment in both materials and labor.
The "wet areas"—the kitchen and the bathrooms—are always the most expensive parts. If you have two bathrooms and a decent-sized kitchen, those three rooms alone could easily take up 40% of your total budget. Then you've got the flooring. Replacing 120 meters of flooring isn't just about the cost of the laminate or wood; it's the labor of leveling the subfloor and the baseboards.
Don't forget the hidden costs. You'll likely need to update the electrical panel and the plumbing. It's not the glamorous part of the job, but there's no point in putting €2,000 worth of designer tiles on a wall if the pipes behind them are forty years old and ready to burst.
The kitchen as the centerpiece
In a reforma integral casa 120 metros cuadrados, the kitchen usually ends up being the star of the show. Since you have a decent amount of space, you can probably fit a kitchen island. If you can swing it, do it. An island provides extra prep space, storage, and a place for the kids to do homework or for friends to hang out while you're opening a bottle of wine.
When picking materials, think about durability. Quartz countertops are great because they don't stain like marble does. Also, think about your appliances early on. If you want a double-door American-style fridge, you need to plan the cabinetry around it from day one. You don't want to realize three months into the build that your dream fridge won't fit through the door or into the gap you left for it.
Lighting: The most underrated element
I see this mistake all the time. People spend a fortune on a reforma integral casa 120 metros cuadrados but then just stick a single light bulb in the middle of each room. Lighting is what creates "vibes."
You want layers. You need your "task lighting" (bright lights over the kitchen counter or in the bathroom), but you also need "ambient lighting." Think about dimmable LED strips in the ceiling coving, or wall sconces that create a warm glow in the evening. In a 120m² space, you have enough room to play with different zones. You can use lighting to visually separate the dining area from the lounging area without actually needing a wall between them.
Energy efficiency and windows
If you're doing a full renovation, it's the perfect time to think about your utility bills. Replacing old, drafty windows is one of the best things you can do. Go for double or triple glazing with thermal break technology. It might seem expensive upfront, but you'll notice the difference in your heating and cooling bills immediately.
Also, consider the insulation in the walls. If you're already stripping the place back to the bricks, adding a layer of rock wool or high-density insulation is relatively cheap and makes a massive difference in how quiet and comfortable the house feels. A 120m² home can be expensive to heat if it's leaking air everywhere, so don't skip this step.
Flooring choices for a cohesive look
One trick to make a house feel bigger is to use the same flooring throughout the entire space. If you have different tiles in the kitchen, wood in the living room, and a different tile in the hallway, it "breaks up" the floor and makes the house feel like a series of small boxes.
Using a continuous floor—whether it's a high-quality laminate, engineered wood, or even a large-format porcelain tile—creates a visual flow. It leads the eye from one room to the next without interruption. Most modern materials are durable enough now that you can even put the same "wood-look" porcelain tile in the bathrooms and kitchen that you have in the bedrooms.
Survival tips for the renovation process
Doing a reforma integral casa 120 metros cuadrados is a marathon, not a sprint. You're looking at anywhere from 3 to 6 months of work, depending on the complexity and how many surprises your house is hiding behind the walls.
My biggest piece of advice? Don't live in the house while it's happening. I know it's tempting to save money on rent, but living in a construction zone with no kitchen and constant dust is a recipe for a breakdown. If you can, find a short-term rental or stay with family.
Also, expect things to go wrong. It's just the nature of the beast. A delivery will be late, a tile will be out of stock, or the plumber will find a weird leak. If you go into the project knowing that there will be a few bumps in the road, you'll handle the stress a lot better. Always keep a 10% to 15% "emergency fund" in your budget for these exact moments.
Wrapping it up
At the end of the day, a reforma integral casa 120 metros cuadrados is your chance to build the home you actually want to live in, rather than just adapting to someone else's old layout. Focus on the flow of the space, invest in the "bones" of the house like plumbing and windows, and don't be afraid to open things up.
When it's all finished, you'll have a space that feels fresh, modern, and perfectly suited to your lifestyle. It's a lot of work and a fair bit of stress, but when you walk into that brand-new living room for the first time, I promise you'll feel it was worth every penny. Just take it one step at a time, hire professionals you actually trust, and keep your eye on the finish line.
