Looking for Annexe to Rent Only

Looking for annexe with ample space to rent in the area of on the West Berkshire/Hampshire border inclusive of all bills. Preferably around Headley, Kingsclere, Ashford hill and any areas close to. (I grew up in Headley for 18years and still have close family living there and I would like to move back to the area) my budget is a maximum of £1,000 a month and would need to be inclusive of all bills. (Negotiations can be had) I am not looking to share with anyone. PLEASE DO NOT MESSAGE ME ABOUT ROOMS THIS IS NOT WHAT I AM LOOKING FOR.

I am a working professional and usually is a mix of WFH and in the office - I currently work in Newbury. I am also away most weekends in my campervan mountain biking (so it’s likely that I won’t be around much at weekends) I also have extended periods of staying away in my campervan. Would ideally need space for parking as well as access to a garden. Ideally will also allow guests from time to time :)
