State aids

The Luxembourg State provides a broad array of individual housing subsidies to facilitate the purchase, construction or renovation of a property.

Premiums and interest subsidies

You are buying, building or improving your home? You might benefit from a premium as well as an interest subsidy and aid to cover the architect or engineering consultant’s fees when you meet certain conditions.
These include criteria on the useful floor space, as shown here: 


Single-family home Apartment

65 m² minimum

45 m² minimum

140 m² maximum

120 m² maximum


Useful floor space is the surface area of the home inside the exterior walls, except for cellars, garages, attics, workshops and other professional outbuildings and, in joint ownership properties, excluding the communal areas. However, attics or areas permitting the fitting out of attic rooms are included, on condition that the minimum height of the attic space is at least 2 metres, that it can be accessed normally and has a window measuring at least 0.375 m x 0.750 m.

These surface areas may be increased by 20 m² for: a third and any subsequent child or a direct ascendant living in the household if: the household counts more than four people, the ascendant does not own their own property and the ascendant cannot live alone due to their state of ill health. For properties built before 10 September 1944, the surface area conditions do not apply.

Please get in touch for further information or to calculate the amount of aid you are entitled to.
