Shed advice

Hi, I'm looking for a bit of direction from anyone who recently got a shed or built one themselves maybe.

I'm in the market for a new shed. The shed will be used for storage and as a bit of a workshop as I'm getting into woodworking so need an area to play around and do some diy projects etc.

I was initially considering a 16x10 shed, but there's easily enough space for 20x10 if need be, (maybe slightly bigger again) and if the additional cost isn't crazy. I'm kind of thinking that if I just go for the bigger size then it's future proofed. But again, it comes down to cost really.

From a bit of research online I've seen some eye watering quotes. I've also found some reasonably priced options but I'm unsure if they'd meet my needs or it the quality would be up to scratch.

There's also a lot of conflicting information online about whether I'd need a concrete pad or prop the shed up on blocks.

I'd prefer a timber shed over a steel one due to looks and customisation possibilities.

Can anyone point me in the right direction where I could source something that ticks all the boxes? I've never built a shed before but I'd be willing to give it a go if that was the best option but I wouldn't know where to look for plans, material lists, cut lists etc.

If anyone here can recommend shed companies that are reasonable and reliable, or if you can advise on a diy build I'd be very appreciative.

I'm based in Meath btw.
