Basically there is nothing wrong with those dimensions. The fact that the room opens to the kitchen makes room mode behaviour unpredictable. The pressure lines will no longer be parallel to the walls but curved, or there may even be "pressure islands". The only way to know beforehand is finite element analysis.

If the fire place is floor-to-ceiling, it too will affect mode behaviour.

Should there be still budget, I recommend an acoustic ceiling, especially if the walls are brick 'n mortar or concrete and the floor is tiled. Our Plameco ceiling has 26 cm air gap above and is extremely effective. It acts as a huge membrane absorber (read bass trap) and handles both vertical and horizontal room modes.
