Garden design

We’re looking to create an amazing design for our long straight garden. We want something modern and functional near the house and a secret hideaway retreat at the back, a tiny house in the woods where we can have a wood burning stove and sleep the night.
We’re a family of 4 with 2 kids age 9&11, we have lots of friends and a large family who we’d love to entertain outside in all weather.
Needs to feel like the outside, but also not be too much maintenance.
Do you think you can help?
Kind regards,
Susie
