Isekai Craft Gurashi ~Jiyuu Kimama na Seisan Shoku no Honobono Slow Life~

Miyabi always had dreams of being an architect, creating buildings that would inspire awe in others. And in the MMORPG Yume Sekai, he was finally able to achieve that dream - even if his constructions were used entirely to house marriage proposals. One day, Miyabi received a message from the admins of the game - as his architecture was so good for couples, they are gifting him with a once-in-a-lifetime opportunity to go to a new world. Assuming they mean a private server, Miyabi accepts - and quickly gets transported to another world.
