I’m looking to build an extension, pre cast concrete or normal route?

Hi

I am starting to plan an extension to my property and have looked at various options and one option that pops up is pre cast concrete, as more and more homes are being built this way has anyone tried extending with it, if you have what’s the pros and cons? The extension is going to be about 30 square meters and there’s plenty of access to the property where it is going, or am I being silly and should I stick to the traditional route of blocks and mortars? Thought process behind it is hopefully it should be a bit cheaper, quicker installation and I don’t have to rely on weather for block layers?
