The 2 extra facilities will overflow into the right corner of the base, as so:

You will need to build 6 facilities that get no adjacency bonuses (Officer Training, Alien Containment, Foundry, Psionic Labs and 2 plot facilities which cannot later be removed or moved), and 2 square blocks of 4: 2 Satellite Uplink + 2 Satellite Nexus for a total of 16 satellites (which is exactly the number of satellites you need) + 2 Power Generator + Steam Generator + Elerium Generator to power the whole thing (a base with such a layout will produce 107 power and draw 102 power you can replace the Thermo Generator with an Elerium generator if no steam block is in a suitable location, allowing you to drop 1 Power Generator and placing one of the non-adjacent facilities there, freeing up a slot in the right wing for another lab/workshop).Īs you can see, 6 + 2 * 4 = 14, the number of rooms in one side of your base + 2. I would recommend dedicated the entire right side of your base to laboratories and workshops, save for 1 or 2 rooms, which you will need for facilities that get no adjacency bonuses.
