Preparing puppy for work

Hey folks, looking for a little bit of advice please.

Bit of info before the question. I live in Cumbria, UK and have a 9 week old golden retriever working line pup. I'll be returning to work in a couple of weeks and I've made plans for her to come with me, though she is required to stay outside. She'll be in a secure courtyard a few metres away from my workbench (I'm a cabinet maker). I've made a decking area with a secure pen and crate setup, similar to what she is used to at home. The area has a roof and is protected from the wind. I'm concerned about her being warm enough, though there are things I can do to help with that.

I'll also be able to continue the 1 hour play/training and 2 hour nap time schedule that I've got her comfortable with. There's also a field for exercise when she's older.

So, my question – Is it actually okay to keep my puppy outside under these conditions? I feel like it's a reasonable solution for an older dog, considering the alternative of being at home alone all day. But an adult would be more resilient to the weather conditions here in the UK. I just worry if I'm doing the right thing. Is it morally okay? Can a puppy cope with being outside like this?

There is an alternative, which is to keep her in our kitchen area. She could still have a crate and pen and would be warmer. My plan was to use this only during the winter months, but now I'm wondering if it's a better option for all year round…

Any thoughts, advice, opinions, suggestions welcome, thanks!
