They're big and noticeable - and on Monday the city of Denver said change is needed.
On Monday, the city's Slot Home Task Force, formed early in 2017, announced its proposed plan to change how slot homes are built.
The amendment would require the dwelling to face the main street on which it is placed. In November, we reported that some researchers have found this type of building orientation can elicit a fear response in people.
Other proposed changes would include requiring developers to add more windows to the buildings, make them shorter and lower the minimum size of the driveways.
City Councilman Rafael Espinoza, who represents District 1, is on the task force as his district has seen some of the most widespread slot home development.
"I won't be so naive to say that we got it 100 percent right [with this proposal]," he said. "I hope we came a lot closer."
Slot homes began popping up in Denver in 2012 as a way to accommodate the city's rapid population boom. Typically, developers will purchase a single-family home, or lot, and raze it before building their slot homes. They face inward so they can use as much of the lot space as possible, maximizing density.
The city assigned a slot home task force to try and amend zoning regulations so the townhomes could better fit in in the neighborhoods they are built.
"This is not going to fix [the slot home problem]," said Lakewood resident Brad Evans. "This is not going to be the answer."
Evans moved out of his Sloan's Lake neighborhood when he noticed slot homes going up around him. He's started a Facebook Page, Denver FUGLY, to highlight the developments, and hopefully, initiate change.
"I think we'll still be talking later about, 'God why are they building these things so ugly,'" he said. "Zoning never really talks about look and feel, and so until neighborhoods get together and say hey we want our neighborhood to look like this, [not much will change]."
Denver has said it is thinking of increasing the number of design reviews needed to build slot homes as a way to address their aesthetics.
The amendment proposed on Monday will officially go in front of Denver City Council for a vote in May.
