From what I gathered of the talk between Gildarts and Makarov when they went to Lumen Historie the guild hall hasn't been destroyed, but sold (at least that's how I interprete the "repurposed" that was mentioned).

With the 30 million prize money from winning the GMG, they surely can afford to buy it back, once the Eclipse crisis is over.

And even if they don't get it due to the circumstances, with their core members back and them being recognized as the strongest guild in Fiore, they'll see a great influx in requests and thus have a lot more income in the future (compared to the 7 "missing years").
