I’m worlbuilding a city full of treehouses for my Drifting Amalgams universe. Here’s what I’m asking and learning to create a rainforest community.

How to Worldbuild Homes in Sci-Fi Worlds
Environment and community are two essentials for worldbuilding a sci-fi home.
Environment guides choices like building materials and style of residence. While community helps turn a physical space into a place for social connection.
Questions about special building constraints or construction advantages can help.
When exploring these, you’ll want to think about things like gravity and magnetism, or planetary phenomena like earthquakes.
And to worldbuidl beyond just a house to create a neighborhood, look at gathering places that foster community. Things like community centers and libraries.
Greenspaces, too, can bring people together–especially for sporting events.
And remember it’s sci-fi. Only the culture you’re building limits your creativity.
…That’s why it’s time for me to build a community of treehouses.
How I Worldbuild Treehouse Environments
As I’m worldbuilding treehouse communities for my orangutan-based species, I’m finding some interesting real-world inspiration.
For the large, sturdy structures I need, I researched Earth’s biggest trees. Hyperion, a redwood in California, stands tallest at about 380 feet. That’s roughly 32 floors in building terms.
Based on this, I’m making my world’s trees an average of “Hyperion height”. And since orangutans as well as Hyperion’s species are native to rainforests, I have the perfect environment for my treehouse community.
Now, I need to figure out how to make treehouse residences more than just standalone structures.
How I Worldbuild Treehouse Communities
Community is about neighbors, but it’s also about amenities. Places like libraries and parks do a lot to create a sense of belonging.
This poses an interesting challenge as I create a community of treehouses.
Luckily, the trees in my world are much larger than those native to Earth. With them, I can create neighborhoods of multi-use tree buildings akin to skyscrapers.
Each tree houses schools and community centers. And I can designate full groves for entertainment and fashion districts.
Plus, parks can …branch out from the trunks, and they will be abundant throughout the neighborhood.
With skyways connecting nearby buildings and easy aerial transit, the people of this world have a convenient way to live their lives in the clouds.
Model of Tree-partment Community
Welcome to one of Prime Metropolis’ major government buildings.
Zoned with levels for industry, residential, and administration, government functions can be found at the top of the tree.
Aerial roots are trained to secure buildings to the side of the tree while engineered roots provide swinging playgrounds for children.
A large red communications antenna help officials stay in touch with the rest of the forest city.
And since most transportation is aerial based, there are beacon lights on the tops of most structures to prevent collisions. This includes the park to keep children safe.
Po'ongabel rely on public transit for movement between trees. So transit stations are abundant for individuals–whether they need a maglev train to another tree in the city or a bus to another level on their current tree.
And with ground transport for cargo and skyways for short trips, Prime Metropolis is the perfect home for the cosmopolitan Nation citizen.
Until next time, keep creating.
