Modern House Numbers Our larger format matt black floating house numbers are ideal for a bold statement to your luxe home! Powdercoated in matt black, these beautiful aluminium house numbers are corrosion resistant so perfect for environments with higher levels of salinity. The numbers are 150mm and offset 10mm from the wall/surface. Spacers, fixings and anchors are included. Please note that the '0' is styled in a wider format similar to a 'O' in our 15cm floating house numbers.
