We need a debate on standards in housing now. The new approved house types do not address demographic trends and changes in housing need (“Super models”, 7 November, page 24). The Housing Corporation claims they are minimum standards but they will be used as benchmarks when, in our view, some do not even meet the corporation’s mandatory development standards – let alone the rising expectations of residents.

Let’s not have a discussion about ensuite toilets when these designs don’t even allow access to the toilet for many of our customers. Can the corporation really say these house types are fit for purpose?

The corporation must withdraw plans that do not meet scheme development levels.

All approved designs must include Lifetime Homes standards.
