Hire cheap, slim construction of a particular shape (13)

I believe the answer is:

hemispherical

I'm a little stuck... Click here to teach me more about this clue!

'hire cheap slim construction of a particular shape' is the definition.
I can't tell whether this defines the answer.

'hire cheap slim construction' is the wordplay.
'construction' indicates an anagram (answer constructed from certain letters).
'hire'+'cheap'+'slim'='hirecheapslim'
'hirecheapslim' anagrammed gives 'HEMISPHERICAL'.

Can you help me to learn more?

(Other definitions for hemispherical that I've seen before include "Of half a globe" , "Domed" .)

I've seen this clue in The Daily Express.
