One possible story could be about a wife who discovers a new passion for gardening. She turns the backyard into a beautiful three - dome - like garden area with different types of plants in each 'dome' - one for flowers, one for vegetables, and one for herbs. It's free in the sense that she uses recycled materials to build small structures for the plants.
There could be a story where a wife decides to start a free community project in the neighborhood. She envisions three domes as different areas for activities. One dome is for art classes for kids, another for book clubs for adults, and the third for yoga sessions. She manages to get volunteers and donations to make it all happen without charging anyone.
A wife might have a dream of creating a three - dome - like space in her home for different purposes. The first dome - like area is a reading nook filled with her favorite books. The second is a small meditation space, and the third is a play area for the family pets. She makes it all free from clutter and a haven for relaxation by decluttering and repurposing old furniture.
