Tips from some experts loading up sheds for modern yards (6)

'modern yards' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps there's an association between them I don't understand?

'tips from some experts loading up sheds' is the wordplay.
'tips from' indicates taking the first letters.
'loading' indicates putting letters inside (some letters are loaded into others).
'up sheds' becomes 'mews' (I can't justify this - if you can you should believe this answer much more).
The first letters of 'some experts' is 'se'.
'se' inserted into 'mews' is 'MEWSES'.

'for' acts as a link.
