After entering house number it appears in red suggesting that it does not exist, The house has been there for around 90 years . My Son lives in that number. Many other numbers in that street also show red. Similarly a house I used to live in and was built around 1936 also shows red together with many numbers in the street. The first example is in Cardiff the second example is in Edinburgh
