8_tgMqnX-o8 0:00–1:03 — I'm Valery Augustin and I've been an architect in Los Angeles for over 20 years.
8_tgMqnX-o8 1:06–2:07 — The construction of dingbat apartments really exploded in the post-war boom of the '50s and '60s in Los Angeles when many people were moving for jobs.
8_tgMqnX-o8 2:08–3:13 — So one of the first things we're gonna see when we look at this image is how closely spaced all these buildings are to each other.
8_tgMqnX-o8 3:17–4:18 — Whereas the dingbat apartment stacked and maximized the property for a maximum number of units, bungalow court apartments offered a taste of single family residential living for wo…
8_tgMqnX-o8 4:20–5:24 — They're also an endangered species in Los Angeles, much like the dingbat apartment, because current zoning laws wouldn't allow for this many units to be built on these size lots.
8_tgMqnX-o8 5:27–6:28 — There are small courtyard spaces, the courtyard is still landscaped and abundant, natural light goes into every unit.
RL7BECNn-RI 0:00–1:02 — And I've been an architect in New York City for 35 years.
RL7BECNn-RI 1:06–2:10 — And there's a big stoop that leads up to it. Stoop is just a Dutch word for staircase. Servants usually entered down on the ground floor.
RL7BECNn-RI 2:14–3:16 — So that's the basic building block of a New York City block.
RL7BECNn-RI 3:18–4:24 — As an overhead view, you have one room leading into another room.

字幕依据：I'm Valery Augustin and I've been an architect in Los Angeles for over 20 years. Today I'm going to break down architectural details of some of the most popular housing styles in Los Angeles, from some of the earliest built structures in California. 8_tgMqnX-o8@0:00
字幕依据：So one of the first things we're gonna see when we look at this image is how closely spaced all these buildings are to each other. There's only street frontage, which is dominated by the parking spaces for the cars and every building just has a tiny side yard, which you can see here or there. 8_tgMqnX-o8@2:08
字幕依据：They're also an endangered species in Los Angeles, much like the dingbat apartment, because current zoning laws wouldn't allow for this many units to be built on these size lots. The houses were small, typically five to 600 square feet, but you could essentially fit sometimes four to six units on the same lot that would hold a single family residence. 8_tgMqnX-o8@4:20
字幕依据：And I've been an architect in New York City for 35 years. Today, I'm gonna break down the architectural details of some of New York City's most popular apartment layouts. So a brownstone is just one house in a series of row houses along the street that's actually made out of brownstone which is a type of sandstone. RL7BECNn-RI@0:00
字幕依据：And there's a big stoop that leads up to it. Stoop is just a Dutch word for staircase. Servants usually entered down on the ground floor. And the family entered on what was called the parlor floor. And the parlor floor is elevated just to avoid all of the horse manure that filled the streets of mid 19th century New York. RL7BECNn-RI@1:06
字幕依据：So that's the basic building block of a New York City block. And if you multiply that by 20, you pretty much get a mile, and that's why 20 New York City blocks is considered one mile. So you'll notice in these overhead shots that there's no alleyways behind these rows of houses. RL7BECNn-RI@2:14
字幕依据：As an overhead view, you have one room leading into another room. So if this was the flat, like that, there'd be one room here and another room here, another room here. So if I'm in this room, in order to get to any other room, I've gotta pass through each room if I wanted to get to the back room. RL7BECNn-RI@3:18
字幕依据：And usually, there were just like three rooms. There was a bedroom, a kitchen, and maybe there was another room between them. So originally, when these were built, a lot of these rooms didn't have any light and air. So light and air means natural light and operable windows to let fresh air into the rooms. RL7BECNn-RI@4:25
