Austin | Railyard | Two Towers | Proposed

[The ATX]

Filed for AULCC. These are going to be big.

ATX East Tower = 500 Apts. + 300 Condos + 15K Sq. Ft. Retail

ATX West Tower = 884K Sq. Ft. office + 15K Sq. Ft. Retail

Holy shit. It's real.

Can someone do some quick calculations to estimate the heights?

Let’s just assume those spec renderings were in the right ballpark. Hell, they might even be real renderings of the actual current design. So... ~950’ residential and ~750’ office.

If you want something a bit more specific, a quarter block in Austin allows around 15k square feet for a floor plate. For the office tower, that equates to 59 floors. Assuming a relatively conservative 12’ slab to slab height with no amenity floors and architectural flourishes and not counting the lobby or retail, that’s 705’ already.

For the condo + apartment tower, I’ll assume an average of 1000 square feet for the apartments and 1500 square feet for the condos. That’s 15 apartment units per floor and 10 condos per floor for about 30 floors of each. Again not counting amenities, retail, lobbies, variations in floor plans, architectural aspects, etc, which could all greatly affect height that gives you at least another 700’ tower.

Thanks! That's what I was looking for. 12' for office floors is pretty conservative, isn't it? Am I mistaken, or have I seen it estimated at 14' before?

Either way, add in the amenities/lobby and a crown, and this thing will be huge.

Yea, that’s conservative.

Although now that you reposted the renderings, I don’t think those are current. Notice that the east tower is labeled as having office, but the official filings do not have office in that tower

These properties are each 1/2 block or roughly 35,000 square feet. You also forgot to account for about 20 levels of parking.

Each tower is 1/4 block, not 1/2. The property itself is 1/2 block as a whole, extending from the alleyway to one street.

FWIW, I used google earth to measure the dimensions of the current buildings to estimate what floor plate square footage would be for each of two replacement towers.

And yes — I did forget parking, but it seems like parking might be mostly underground here.

Are you sure? Tract 1 is between the alley and 4th Street - Brazos and San Jacinto. Tract 2 is between the alley and 4 Street - San Jacinto and Trinity. That equals two half blocks or one whole block. That is how I see the site plans as they exist now for the Railyard Condos.

The "renderings" on page one show around 15 levels of above-ground parking for each tower.

I don't really care to do the math, but for comparison sake, these lots are 130 feet by 272 feet with 800 units in the residential tower. 360 Condominiums has 433 units, and the 360's tower's footprint is 100 feet by 272 feet. 360's roof is 472 feet 6 inches.

So wwimv's estimate of around 950' would sound about right.

Based on this model, the residential tower should be between roughly 875' & 1,075' (depending on amenity levels & crown height).

If the building actually ends up reaching these heights, it wouldn't just be the tallest all residential building west of the Mississippi River. It would likely be the tallest outside of NYC and Chicago.

From 112 units to 800 units plus office and retail. Massive increase in density here.

Someone noted this in the econ dev thread, but it's worth repeating here. Just the fact that something this size is moving forward might indicate there's a client or clients with strong interest in it. The alternative -- which is presenting it on spec -- seems really far fetched.
