Question

what's the meaning of t1 ,t2,  t3 for the house ?
what do these words mean when refering to an apartment or a flat?

Answer

This is apparently a French usage.

T1, T2, T3 ... T# corresponds an apartment with the indicated number (#) of main rooms (living room, dining room and bedrooms). The kitchen and the bathrooms are not included.

Thus, an apartment with a living room and two bedrooms is a T3.

Example: T2 = apartment with 1 bedroom + 1 living room.

Example: T3 = apartment with 2 bedroom + 1 living room.
