I think the idea is impractical, It's too narrow a space for plants and furniture and any people. The best use for this space is exactly as what it was designed for: an outdoor vestibule.

You could put a bench or a couple of small chairs/bistro set in there, especially towards the end wall or under the window. It doesn't look like the covered veranda is used for any sort of access to anything other than the door so keep that end free.

Some shade tolerant container plantings, a small rug and some colorful pillows and it could make a very pleasant sitting area. But not exactly what I would consider a "hang out" space :-)

And I have no idea what you intend with the wood pellets.......

PAllets, perhaps? DIY furniture?

Thank you for the input. I was intending to use the wood pellets as seats. Painted white and use colorful pillows. Actually the width is 1. 5 Metres

🤦‍♀️ OH dear typo error 🤣. Thanks for that.

Yes, the pallet bench is too rustic for the position imo. The verandah needs painting and then a more elegant bench or two chairs. Perhaps cane or metal.
