Double room + ensuite + private living room option

I have a big place (2 living rooms, kitchen, dining room + 5 bedrooms) that is too much for me on my own. Ideally looking to rent out the bedroom, ensuite & private living room / office that is on it's own level of the house (especially if someone works from home), so there is effectively a self contained annex within the house beyond just bedroom / bathroom for whoever moves in.

Looking for a super-chilled housemate, who likes dogs (I have a little cockapoo called Lola) tidy & relatively quiet. Might be a "unicorn" search as my last housemate who lived here for 8 years was super cool.

About the house / room:

A huge house & gardens with large rooms throughout decorated in New York loft style + Scandi decor. My office / recording studio is my private man-cave but there is a lovely living room that could be a shared space. Large garden with a variety of BBQs + ponds + a summer room for autumn / summer evenings outdoors.

The house has been designed for outdoor living, with bi-fold doors off the dining room / kitchen with decked areas and outdoor cooking / dining areas.

The HUGE bedroom on 3rd level of house (25+m2) can be private living room + office for home working, which in addition to the en-suite bedroom, which would be an additional £275 per month but it would mean you would have something like 50m2 of your own private space within the house (so only the downstairs kitchen would need to be shared).

About me:

I'm American born to German / Finnish parents who has lived most of his life in UK. I enjoy tennis, snowboarding holidays, kitesurfing, music production / DJing, occasional table football, talking business theory, cooking (especially new dishes) & generally chilling out. I retired early in life after being involved in dot. com development. During the summer I do LOTS of BBQing (American style, as in with offset smokers / Big Green Egg BBQs).

I have a long-term girlfriend & daughter in Dorchester, who I visit normally for 1-2 days per week or they come over here. Somethings you might find "a challenge" - I don't drink, really don't like football and enjoy chatting about something meaningful rather than just "sh1t talk" (that is the Finnish side of me, I guess).

Happy to start talking with people to find out if there might be a good match for a housemate but no rush on this, at all. :)
