A sunroom in a house: windows on every side, morning light, a round wooden table under a pendant lamp, and plants

Find a home you never want to leave.

Light that reaches the back of the room. Ceilings you notice. We measure how a home will feel to live in, from its floor plan, before you buy it.

The problem

Listings measure energy. Not life.

A listing shows the price, the square metres and the energy class. So that is what new buildings are designed to hit.

Big windows make a good energy class harder to reach. Small ones make it easy. A flat can be rated A+ and still feel like a box.

Buyers cannot ask for light, tall ceilings or solid walls, because no listing measures them. Airloom does.

The check almost nobody makes

The lot across the street is empty today, so the flat is sunny today. The zoning plan says how tall it may be built. We read it, and tell you how much sky you could lose.

See the home it could be

Most buyers see a house as it is. We show the score it could reach, and the moves that get it there.

  3. Remove the loggia infillno structural change+8

Whether a wall carries load cannot be known from a plan alone: every "probably" is confirmed by a structural engineer before anyone picks up a hammer.

Buying a house to renovate? It is part of the Airloom Report.

Build it with friends

Near Lisbon, a duplex with a double-height living room, a wall of glass, a garden in the middle and a shop downstairs is listed at €4 million. The things that make it lovable cost a fraction of that.

A few households, each putting in what a good flat costs anyway, can commission a building like that. No developer between you and tall windows. Neighbours you chose.

Why you can trust a score

Never paid by those who sell or build

No seller, developer, builder or prefab maker pays us to be rated, featured or recommended. Not once.

Every number has a source

The plan, the page, the date. Where a developer publishes nothing, we say so.

The method is public

Published before the first named score, so anyone can redo the sums.
