Robin Nest - how not to disturb

Hello,

I've just discovered a robin nest tucked behind my shed. Absolutely wonderful, except my plan was to demolish the shed!! I dont want to disturb the nest, so willing to wait, but wanted to make sure I won't cause them problems. From my understanding, once the chicks fledge, the nest won't be used again (at night or for a future clutch). Is that correct?

TIA
