A "bubble" has appeared under my living room floor.

Hi all
I live in a mid-terraced house. On the ground floor living room floor, there is a slight "bubble" that has appeared. Almost like the wood flooring does not quite fit but I think it is getting worse.
You notice it a lot when walking as you step on one hump and it will move it to another location. I initially dismissed it as poor flooring (we've been here for years" that has somehow got worst but it now looks like it is expanding in length. Any ideas?

Could be a leak. My parents had this, warping of the wood and it was a few days later major leak found and all the floor ruined.0

Lift the wood floor at that point and investigate.Impossible to diagnose from your limited description.0

JP, what kind of flooring is it? And what's underneath - 'solid' or 'suspended' timber floor construction?

just your standard wood floor. When I knock on the affected area, it definitely sounds hollow in comparison to the rest of the floor. Anyway a pretty hopeless DIYer can pry one of these off to see the issue?

My money is on lack of expansion space where it meets the wall.3

Can I ask Jonathan when the floor was laid, and who did it?
It looks like engineered wood flooring. Do you know what it is, exactly?
No reliance should be placed on the above! Absolutely none, do you hear?2 -

The lack of space seems like the obvious thing but why is it getting worse? If it was simply a lack of space, wouldn't it be the same since the day it was laid?0 -
I would suggest maybe floorboards aren't nailed down but glued to an underlying substrate. In one room in my house this was hardboard and the adhesive under the hardboard failed with age and perhaps the slightest damp causing it to expand and bubble. As you experience this moves around as weight is transferred (with none of the traditional floorboard creaking either). My floor was on a solid concrete base with a 1930s tar based damp course.
