UPDATE 9/6 10 A.M.

State agencies begin removing a structure that was unlawfully constructed on Mauna Kea.

--

Many people have been noticing a small building popping up on Mauna Kea over the weekend, they're wondering what it is and it has been getting a lot of attention on social media.

In the span of just a few months, protectors of Mauna Kea haven't just come together against the TMT but have also built what looks like a small town at base of the mountain with tents, food and even classes.

However, on Friday a more permanent building was seen coming up.

In this video taken just off the Daniel K. Inouye Highway near the Mauna Kea Access Road you can see a wooden building right near a group of tents.

"We got a library being built, we got kanakas getting established on their national lands."

The group there calls it a small library and learning center and it is going up quickly. While the land is owned by the Department of Hawaiian Homelands, it wasn't approved by them.

"As far as I could check there was no permit drawn by anyone. So as far I'm concerned there is no permit," Mayor Harry Kim said.

Without a permit the new building may not last long.

The Department of Hawaiian Homelands says they've told protectors it's not permitted and that after a notice to vacate is given the Department of Hawaiian Homelands could take it down as soon as they have the resources.

The Royal Order of Kamehameha 'Ekahi and Pu'uhonua O Pu'uhuluhulu gave a response saying they want the base of the mountain to remain a safe haven for protests and they have no intentions of building a permanent village.

The Pu'uhonua says that they don't endorse the building of the structure and that they want to maintain as light a footprint as possible.
