The RUST Foundry Clan Base Design (2019)

The RUST Foundry Clan Base Design

The Foundry Clan Base Design video was created by our partner Rust Daddy.

This clan base is designed for vanilla gameplay servers and is intended to be a complex clan base design with three different levels of completion. This base is a follow up to The Colossus Clan Base Design, in which numerous areas were improved upon.

Features this design improves upon:

  • At level 3, it can house 24 large furnaces
  • Disconnected multi-tool cupboard design
  • Easy access helipad with copious space for rough landings

This base utilizes the disconnected multi-tool cupboard concept, stair foundation, build privilege transfer trick. The trick allows for each external tool cupboard to be disconnected should any tool cupboard need to be replaced, which is handy for recovering a raided compound.

The sheer size of the compound is daunting for any set of raiders. This clan base design is a complex, expert-level build. It will take time to learn the full design’s footprint, but it is certainly worth the time. Be sure to check out the Fortify link below to assist you in the base design-build.

Video Transcript

What’s up guys, Rust Daddy here. A few months ago I introduced the Rust community to colossus, my biggest and most ambitious project yet. Despite the complexity of the build and to my surprise, the design received a lot of attention. One of the more unique properties of the base was the integration of multiple large furnace bases into the main base structure that both protected the furnaces and served as an additional honeycomb for the base itself.

The feedback regarding this feature was mostly positive and led me to further develop the idea of a large group utility base that would be relatively secure and easily expandable should the resource demand of the group increase. In this context, the foundry is a furnace based compound that utilizes a multi-TC concept, combined with a stair foundation building privilege transfer trick that was first introduced by Evil Wurst.

The trick allows to easily disconnect each external TC from the remainder of the base should any of the TC’s need to be replaced. This is a very handy technique when trying to require a compound that has been raided. In such a case you can break the foundation behind the armored stairs, replace the missing TC, and then simply place back all the foundations to reconnect the structure. Moreover, the centralized loot rooms make the base rather cost and effective. In effect, the compound is relatively difficult to raid and grief, which should ultimately discourage potential raiders. 

Before I begin building the base, bear in mind that this is going to be an expert build, so I expect you to put your own spin on the design. Moreover, throughout the video, I will assume that some of the building steps like upgrading, or finding good spots for traps and water turrets are self-explanatory. Instead, I will focus on showing how to build the base in its final tier and suggest the optimal building sequence to do so. Finally, I want to give special thanks to Classy for making the custom map, and to Nagas for making the track that for both use and making the cinematic. I left the contact details in the description, so make sure to check them out. 

Main Base Core 

We will begin building the base from the main base core. To build it, you will need 135 HQM, 1.3 key metal, and stack of stones and wood each. In addition to that, you will also need a TC, 3 garage doors, 2 reinforced glass windows, and some storage containers.

Once ready build a hexagon core, making sure the lower foundations are well off the ground and you can still place base foundations as well. Now place two armored walls and armored floor triangle on top. Place the TC inside and close it with a stone window frame and fit it with the reinforced glass window. Once surrounding the hexagon with walls as shown and finally add a metal wall frame fitted with the garage door.

Then seal the roof. Shield the loot room to the left of the TC, and close it with a garage door. You can fill the loot room with containers of your choosing. You can also fit the vending machine on a triangle in front of the TC for more storage. If placed correctly you should be able to fit a small box on the floor and close it up with a stone window frame and reinforced glass window. Lastly, fit the remaining slot with an additional garage door as well.

The base core is now complete, however it still lacks proper airlock and is an easy target for door campers. Therefore, next we will be concentrating on completing the main footprint and building the external TC’s which will allow us to seal the area into a precisely shaped compound. 

External TC’s

Before you begin gather 294HQM, 20.7 thousand metal, 17,000 stone, and 10.5 thousand wood. In addition to that have garage doors, reinforced glass windows, and storage containers ready. Go outside and surround the core with triangle foundations as shown. Now pick a corner and place a twig foundation and a triangle foundation on the side. Then build eight foundations out, and come back with four triangle half-moons, and add an extra triangle foundation at the end.

Break all but the last triangle foundations, upgrade those to metal, and then proceed forming the footprint of the first furnace node. Place two raised triangle foundations on the sides, followed by four square foundations as shown, and the raised triangle foundations all around. Place one more raised armored triangle foundation at the end, and follow up with the raised armor stair foundation facing outwards.

Lastly, form a hexagon for the external TC as shown, keeping the innermost foundation wood. Place two metal walls in the outmost triangle and place a TC inside. Close the TC with a stone window frame fitted with a reinforced glass window. Seal the perimeter of the hexagon with metal walls, placing a half hole on top of the stair foundation instead. Then form a metal shelf in front of the TC and a stone shelf on the opposite side. Place three garage doors inside as shown, and then seal the roof leaving one floor triangle open.

On top, you can place three stone walls and a garage door to form an entrance, and add an additional stone shelf for extra storage. Finally to match the rocket cast, honeycomb the outermost triangle that contains a TC. Once done repeat the process five more times around the base. Once again you can fit each external TC base with containers of your choosing. 


So with the external TC’s now in place, and before building the furnace nodes, we will first focus on enclosing the entire structure behind compound walls for added security. For this step you will need 6 high external stone gates, and 18 high external stone walls. In addition to that, you will also need 6 metal barricades.

Before you start placing metal barricades on each of the external TC’s outermost stone triangle. You can do this by placing a few twig triangles, placing the barricade, and breaking the twig. Once done proceed with the compound. Place twig foundations and triangle foundations directly outwards from two neighboring raised triangle foundations of the furnace nodes.

Position yourself to the center and hold the high external stone gates. You can hold the Alt key to look up and make sure that the top cover is facing outwards. Then use a twig as a guide to place the gate in the center as close and flush to the twig as possible. Now place two high external stone walls on each side of the gates.

When placing the wall use the horizontal metal bars on the side of the gate as a guide in order to position the walls horizontally. They clip the second wall right in front of the metal barricade perpendicular to the external TC wall.

Lastly break one outermost triangle foundation on each side and once again use the remaining twig as a guide to place a high external stone wall right in front of the gates. Repeat this process five more times around the base. The base is now more secure behind compound walls, so it is about time to finally start making good use of your investment. Therefore we will finally start building the first six furnace nodes. 

Level 1 Furnace Nodes

At this stage you will need 4.8 thousand metal, 38 thousand stone, and 6.3 thousand wood. In addition to that you will also need 6 large furnaces, 6 refineries, and other deployable.

We will start with the one furnace node at a time. Begin by placing ten walls on the ready-made furnace node footprint as shown, making the three outermost walls metal. This is where the furnace node neutral will be formed.

Once done, make an airlock entrance closer to the main base and seal the roots of the airlock and the loot room with stone and metal floor triangles respectively. Follow up with one layer of stone walls around the square perimeter and then seal the roofs with two layers of floor frames fitted with floor grills.

Use twig where appropriate to be able to place floor frames at half height. Now go inside and form the loot rooms as shown. You can consider upgrading the wall frame to metal to avoid splash damage. Now fill the loot room with containers of your choosing, then break the twig foundation and place a furnace in the far right corner.

If placed correctly, you should be able to place a few more large boxes on the ground. For easier access, place a ladder on the side of the loot room. Now repeat this process five more times around the compound. The oil refineries may be fitted in the creases between the furnace nodes.

To do that, build twig triangles to form a hollow diamond shape in the middle and place the refinery inside. It may take some time to find the right spot. With six furnaces and six refineries now finally cooking the resources, we focus on completing the main base. 

Main Base

For this step you will need 5.2 thousand metal, 11.7 stones, and 3.2 thousand wood. In addition to that, you will also need garage doors, reinforced glass windows, ladders, and optionally wood shutters. At the core entrance shape a metal chute going up.

Put the metal shelf inside and close it with the garage door. Once done, honeycomb the core with metal and stone walls where appropriate. On the second floor shape the internal hexagon core with metal walls and a garage door on the side. Inside it, form two loot rooms, and fill the rest of the open slots with garage doors. Then seal the roof. Once again you can fill the loot rooms with containers of your choosing, and then proceed to shape the outer corridor.

To do that, surround the hexagon core with stone walls and stone window frames and then form an airlock at the end. Once done fit the window frames with reinforced glass windows and optionally wood shutters on the inside. And then seal the roof.

For easier access into the base, place stone wall frames and a floor triangle on top on one of the external TC’s triangle foundations, and one more floor triangle at the entrance to the main base. If you have a heli, place the ladder by the entrance to be able to get onto the roof. 

Auto Turret Network

Finally, to improve the security of the entire compound, you can set up an auto turret network. For the simplest network containing on and off switches for each of the turrets, you may consider the following scheme.

To power the network you will need a power source that will be powerful enough to fuel the auto-turrets and charge the large battery at the same time. You can choose between solar panels, wind turbines, small generators, or better yet a combination of them. Know that all of them have their own advantages and disadvantages.

Once ordered go outside and place metal floor triangles under every window frame of the main base and employ the auto-turrets. Then proceed setting up the control panel, preferably at a secure location such as the main base core.

Deploy one master switch, three splitters, and six more switches for each of the six auto-turrets. Now grab the wire tool and closely follow the connection sequence. Do not hesitate to pause and rewind the video at any time, and when in doubt consult the schematic that was shown previously.

If you manage to follow the building steps so far, you should have a level one foundry up and running at its full capacity. However, at any stage, you can decide to upgrade the base and increase the production capacity even further. 

Level 2 Furnace Nodes

To upgrade the base to level two you will need 10.4 thousand metal, 33.7 thousand stones, and 8.2 thousand wood. In addition to that you will need sheet metal, and garage doors, furnaces, floor grills, and other deployables. Begin by forming roof entrance chute on the most distal external TC foundations as shown.

Place three wall frames and two-floor triangles on top, followed by two more floor triangles at half height, and one more wall frame, and one more floor triangle on top. Eventually, the wall frame should be fitted for garage doors.

Once done, do this five more times around the main base. Before you continue, honeycomb the roof of the main base with half walls and floor triangles as shown. You can use metal or stone to fill the honeycomb, or you can leave it unfilled to reduce the costs. To make the furnace node footprint, place two raised metal triangle foundations by the refinery. Then place two metal walls in the left for the loot room, and form an airlock on the right.

Now complete two layers of stone walls all around the node, and then level the tops with half walls. Finally, seal the roof with two layers of floor frames and floor grills. Once done repeat this process five more times around the base. For easier access however, consider placing your wall frame and a garage door by the main entrance instead.

You can set up the furnace nodes the same way as previously described, however, if you’re like me and get paranoid about pickaxe raiding, upgrade the left stone wall inside the loot room to metal and rotate it. In addition to that, the upper outmost furnace node walls may be upgraded to the metal as well.

You will find that a large furnace may fit into the far left corner of the node like so. If placed correctly you should be able to place additional large boxes on the ground as well. With extra six furnaces up and running you’ve got yourself a fully functional level two foundry. However, you do not have to stop there. For the ultimate resource cooking capacity, you may decide to upgrade your foundry to the max level. 

Level Three Furnace Nodes

In such a case you will need 15 thousand metal, 47.8 thousand stones, and 11.7 thousand wood. In addition to that you will once again need sheet metal, and garage doors, furnaces, and floor grills, and other deployable.

Begin by making the furnace node footprint. Build four more raised metal triangle foundations by the refinery. Then starting from one side build out three to eight foundations to be able to place raised metal triangle foundations as shown. Repeat the process on the other side to complete the footprint.

Now follow the same steps as previously described to build the furnace node, making the metal loot room on the right and then a garage door pass-through, and an airlock on the left. Now build two layers of stone walls all around. To be able to place floor frames at half-height, place twig on the other side of the wall.

Then seal the roof with the furnace node with two layers of floor frames and floor grills. Repeat this process five more times around the base, and proceed setting up the furnace nodes as previously described. Once again upgrading and flipping the loot room wall.

You can fit two more large furnaces in each of the furnace nodes and place several more large boxes on the ground. With the final building steps now complete, you are now a proud owner of a maxed-out level three foundry. 

Please note that in this video I was going for the most economical version of the base. Never the less, there is still space and numerous modifications that may be done throughout the base to increase its capacity, security, and even function. Lastly, I should stress that expanding the base from its initial level one version may be done in even smaller steps by adding a single furnace node at a time. 

And there you have it.

A large expandable furnace base that will hopefully answer all of your resource demands. So if you like what you saw do not forget to give it a thumbs up and subscribe.
