I like number 3. Minimalistic but I would use concrete slap, no fountain, no bird feeding stations, may be put couple of pots, some outdoor furnitures and set up a BBQ area, aim for low maintenance
👍You laid real turf ( real grass for those not familiar). I dreaded you laid Astro turf and even more dreadful you suggested to HKers to do that., ( artificial grass) because there are too many HKers followed suit ,走佬巴 and posted silly videos boasting how good it looks.🤦♀ You claimed you lived in U.K. for more than 10 yrs, surely you must realised British people love their gardens and endless promotions embrace wildlife, support birds & bees. Maintain green spaces to support environment. Even the late Queen asked to plant a tree for Queen’s Green Canopy project to mark her Platinum Jubilee. Life in U.K.is not insular, think COP 27.
