Hip house numbers: Numerals at Another Country
The actual numbers are made in the UK, crafted from oak and available in numbers as well as lower case letters. Just in case your house is one of those with a 'name'. They have also been UV lacquered for long life, although they will 'age' with the weather and sunlight over time.
Not cheap at £18.49 each, but these should be with you and your own home for the long haul.
