Recommended home builders – Sapporo

Any recommendations for home builders?

We've visited a few showhomes from Cosmo Kensetsu(Hokkaido only?) and visited one today from Sumitomo.

Sumitomo was ok, but for a model home, there was A LOT of melamine cabinetry
It was a 2×6 build which was nice to see, but certainly necessary.

Where the walls met the ceiling, they had this plastic trim which looked really cheap and tacky.

Cosmokensetsu was marginally better, but at least they didn't have the ridiculous trim along the ceilings.

The exterior of the Sumitomo place seemed nice.

Any recommendations from people have built?

Thanks!
