A 10-foot-wide house was built 'out of spite' on a leftover piece of land in Florida and is selling for $619,000. See inside.

"We don't create our own subdivisions and build — typically, we build on lots that exist," he said. "In this particular neighborhood, which is typical of beach areas or areas of high density, you'll get some areas of smaller lots."

The lots were all 25 feet wide, according to Wetherhold, but eventually, some owners started to combine lots together, leaving some uneven spacing.

"They'll say, 'OK, you can build within the setbacks, you can build wider, you can build deeper, you can go up front,'" he said. "Typically, it's a fairly straightforward process."

"What we were left with was to build within the building code, a modern building code that's been revised that's pretty conservative at 35% law coverage and seven-and-a-half-foot setbacks on each side," Wetherhold said. "So it made us build a 10-foot wide house. We had no other choice."

"Had they understood the process better they would've worked with us to help us build a wider home," Wetherhold said. "But their whole idea was once the pot got served, 'We can stop it from being built,' which is counterintuitive because obviously that was not the case.

While it is only 25 feet wide, the lot is 140 feet deep — deeper than some typical lots in the neighborhood, Wetherhold said.

"You're not supposed to put floor area in them, but you can put seating area — so you're not able to stand on it, but you can do build-in seating," Wetherhold said. "We built a ton of built-in seating because it's narrow anyway. To try to put a couch in a 10-foot-wide house isn't really practical."

"The builder's son did this really cool dining table that was made from boards from when our pier was destroyed by Hurricane Matthew," Wetherhold said, referring to the 2016 storm that destroyed a pier in Jacksonville Beach and caused damage throughout the Atlantic coast. "He kept all those boards and then made a dining room table front on it, which was a really cool thing."

Wetherhold said he had a deal lined up within the first week, but it fell through.

"We thought originally we'd be maybe $450,000 to $500,000, and then as it evolved and we started to see it come to fruition and actually walk through it and finish it out, it really felt better than the way it looked on paper," he said. "Ten feet wide does not sound appealing at all, but once you're inside, the typical room is maybe 12 to 15 feet wide.

"I had an open house the weekend after the 'Zillow Gone Wild,' and it was a three-hour open house, and I probably had 300 people to 400 people — which is just unheard of."

Wetherhold said the house is perfect for "a person that wants to be in a neighborhood of million-dollar homes but doesn't want a maintenance factor of that and still wants to be in a nice area and pay about half the price."

"And come to find out, we weren't sure if that was a niche that was out there, but sure enough it is," he added.
