OA custom server on NA - World 1, Monolith: Exo (7145.09,-6868.75) 🥰

I've had a lot of fun with this challenge!

Always wanted to make a build with us (meta's) really small, or like the ants in a way .
And having a huge construction to build into. I also wanted to have a treehouse so this was the perfect oppurtunity to do both!

Its been real challenging to build around such a big tree with clipping issues but I managed and here's the result.

The tree has the exact constructional build as the original and tried replicating each part to those measurements, JUST BIGGER!!!!

You can find the build at Europe ( 6250 , 6720 )

ps: worked hard on lighting so you might wanna visit when its dark outside to see it pop

I played this game once months ago, however I fell out of it after reaching level 50 and doing everything I could in a novice server. After I found out you had to start fresh at the end of a scenario, I didn't want to play again.

However my girlfriend wanted to play and I got sucked into it again, finding myself obsessed with the building aspect, trying to copy this image I found on pinterest with what I have..

Are there any builders out there that have any suggestions as to what I should build or idk tips and tricks for hiding wires and pipes? (not the settings way) or just building in general?

Leaves have started to fall and turned this place into a zen area where you can rest after having a stressful day 🍂 ; come visit and take a break under the warming lights 🧡

Just finished building my Junkpunk treehouse, made entirely from junk collected all over Nalcott!

The treehouse layout is based 100% on the challenge tutorial. If you’re stopping by for a visit, enjoy the piles of golden, crunchy autumn leaves, and don’t forget to explore the surroundings! You won’t be disappointed.

Long shot but here it goes ...my wife and I are new to once human and we're addicted. She purchased ithe romantic misty purple street expansion pack not knowing it was only a part of it. Would someone cool enough friend her and possibly share the entire if not a second or first part of it. She only got 65 pieces included in it. Thanks in advance! We're also very confused on how to link up inside the game even though we are both in manibus. If someone could explain how to link up I would appreciate it!! Thank you red!!!!!!

📜 Event Overview

Built on SEA Once Architect Custom Server, Location:

World 1, Monolith: Exo [Vena Fjord - Hiverail:(564,5071)]

PLEASE come to visit if you can. I put a lot of effort into this one especially in the small details which can only really be appreciated while walking through in game!

Eyrie Ridge sits on top of a rocky cliffside with panoramic views. It may be small, but it has everything you could need!

For this challenge, I wanted to do what I love most: focus on interior décor using a specific color palette, while maintaining harmony between the furniture and the plants. I wanted to create a "home" with a classic and cozy style.

Built a little Mid-Autumn Festival hideaway in the cliffs! Two Asian-style tree houses and a pavilion connected by winding cliffside walkways, surrounded by red maple trees, lanterns and a whole lot of autumn atmosphere. And because no Mid-Autumn build is complete without the Moon Bunny… I also built a giant bunny happily eating a mooncake . Now I just need to figure out how many lanterns is too many…

For this build, I wanted to see if I could push for an industrial garden home.

A mesh up of harsh materials, but softened by lush greenery. There are cozy living areas, gardening space at the entry and a full rooftop garden. Also, a nice sunken fire pit for those chilly nights in Nalcott.

It feels like, and is a functional living space for any gardener, or tiny home lover. A little industrial, a little overgrown and cluttered, but I'd call it home any day.
