Construct new house or Buy used ready house?

AOA All,
I have 7 marla plot in Phase 8.
Is it a wise decision to start constructing house considering the current situation where the cost of construction is high?
or should i sale this plot and add more money and buy ready house 5 marla?
is merging deal beneficial or should sale plot first ?
I need your kind suggestions plz.
Thank you - Jazak.Allah.
