There are many single-story houses in this area.
I'm looking for a single-story shop building.
平屋 is a simpler noun meaning 'single-story house' or 'one-story building', while 平屋建て explicitly emphasizes the construction style (建て). Both are often interchangeable, but 平屋建て is more common in formal descriptions.
Standard spelling. 平屋 (single-story) + 建て (building style).
Abbreviated form, often seen in real estate listings.
Variant using 家 (house) instead of 屋; both are used.
Abbreviated variant of 平家建て.
Compound of 平屋 (ひらや, 'single-story house') + 建て (だて, 'building style, construction'). The reading だて is a rendaku form of たて.
