What to do if I lost my house in Minecraft Creative Mode?

I play Minecraft.

I bought my dream house in a creative way for more than 3 months (I know that survival is better) … Today I go to the Nether portal which for some reason EXPLODED, and when I had rebuilt the portal, I spawned in the middle of it nowhere😭😭😭😭

Can someone help me find my house again? Would be really nice, thanks in advance

Have you memorized the coordinates?

Or being being you in the void around. Then you spawn near the worlds spwn point or in a bed. If you built your house near the world spawn point you can find it again.

Enter / kill
