The building, from primary sources
The Royalton at 3333 Allen Parkway: A Buyer's Guide to the Building
Updated August 2026
Bottom line: The Royalton is a 33-story condominium tower at 3333 Allen Parkway, built as a rental building in 2002 and converted after a December 2004 sale. It holds 253 homes across 27 floor plans, facing Buffalo Bayou Park.
What is The Royalton, and how is it different from Houston's other condominium towers?
The Royalton is a 33-story condominium tower on the north side of Allen Parkway, facing Buffalo Bayou Park. It holds 253 homes, and those homes are laid out across 27 different one, two and three bedroom floor plans. That combination is the fact to hold on to, because it is what makes this building a different problem from the other Inner Loop towers.
A building of seventy or ninety homes offers a handful of plans, and a buyer's real decision is whether the address and the price are right. Here the address and the price band admit a much wider set of buyers, and the decision moves inward: which of the 27 plans, on which floor, facing which way. Two homes in this building with the same bedroom count and a similar stated area can be quite different places to live, because the plans are genuinely different rather than mirrored variants of one another.
The other consequence of scale is that the building generates real transaction history. A 253-home tower produces enough sales a year for a median to describe something, which is not true of a building a third the size. That does not make a building-level statistic behave like a city-level one, but it does mean the numbers on this site are worth reading rather than merely reporting.
Who built The Royalton, and when was it finished?
The tower was developed by Simmons Vedder Partners. Its architects were The Steinberg Design Collaborative and Ambrose McEnany & House. Construction started in October 2001 and the building was complete in December 2002. It opened as a rental building carrying its street address as its name, and it was sold in December 2004, 85 percent leased at the time of sale, to a condominium converter. A widely used building page names that buyer as Group LSR, a Montreal-based developer, and it is the conversion that gave the tower the name it uses now.
This two-stage history explains something that otherwise looks like a gap in the record. Search for the origins of a building called The Royalton and very little comes back, because the construction record was filed under 3333 Allen Parkway and the name arrived two years after the building did. The developer's own project record is the primary document for how the tower was built; the recorded declaration and the association's documents are the primary record for how ownership here works. They are different filings made by different parties, and a question about one is rarely answered by the other.
The distinction is not academic for a buyer. The date that governs the declaration, the allocation of common expenses, the association and every governing document handed over at a sale is the conversion, not the completion. A source that gives a single year for this address has quietly chosen one of three, and it is worth knowing which.
| Source | Stories | Homes | Floor area | Year given |
|---|---|---|---|---|
| Developer's project record | 33 | 253 one, two and three bedroom units and 4 penthouses | 417,748 square feet building area; average home about 1,650 square feet | Construction start October 2001; complete December 2002 |
| Construction trade report, August 2022 | 33 | 253 | 550,000 square feet | described as an 18-year-old building |
| Widely used building page | 33 | 253, in 27 varying floor plans | not stated | 2003 |
| Market-statistics feed behind this site | not stated | not stated | not stated | not stated |
What does the published record disagree about?
Two things, and both are worth understanding rather than resolving by picking a favourite. The first is floor area. The developer's project record gives a building area of 417,748 square feet; a construction trade report covering the 2022 flooding described the same tower as a 550,000-square-foot building. Neither is likely to be wrong. A developer's building area normally counts the space built to lease or sell, and a figure quoted in a construction context often counts the whole structure including the parking podium and back-of-house space. On a tower like this one that difference is large.
The practical upshot is that neither figure should be divided by 253 to get an average home. The divisor and the numerator do not describe the same floor area, and the answer that falls out is a number with no referent. The developer's own stated average of about 1,650 square feet is the figure to use if an average is what you want, and it is still an average across 27 plans that differ substantially.
The second disagreement is the year, and it comes from the building having three defensible start dates: completion in December 2002, service as a rental building through 2003, and the conversion to a condominium regime after the December 2004 sale. A trade report described it in 2022 as an 18-year-old building, counting from the conversion. A widely used building page gives 2003. The developer's record gives 2002. All three are on the table above.
What does The Royalton offer its residents?
A widely used building page lists a pool with a sundeck, a fitness centre, a private theatre, a ballroom with a caterer's kitchen, a recreational game room, a garden cocktail terrace, a business centre, guest rooms, an outdoor kitchen and storage, alongside 24-hour concierge service and valet parking. Homes carry assigned spaces in a private garage, with valet and self parking both available and valet offered to guests. The same source describes an open pet policy with no restriction on the number or weight of pets, limited to cats and dogs, and the building carries a pet run.
An amenity list of that length is better read as a payroll than as a set of features. A staffed lobby, round-the-clock valet, a theatre and a ballroom are people and plant under contract, and the monthly assessment is the only thing paying for any of it, whether or not a particular owner ever uses them. For a buyer who wants the services that is a fair trade and part of why the building is on their list. For a buyer who does not, it is a recurring cost attached to things they will not use, and that is a legitimate reason to look elsewhere.
One caution applies to everything in this section. These are listing fields rather than statements from the association, so they describe what was offered when a listing was written rather than what is staffed and open today, and a pet policy in particular is a house rule the board can amend. If any of it is decisive for you, ask for the current rules and the association's own documents rather than relying on a published summary, this one included.
What is across the street from The Royalton?
Buffalo Bayou Park, a 160-acre green space that runs from Shepherd Drive to Sabine Street, between Allen Parkway and Memorial Drive. The Royalton stands on Allen Parkway inside that stretch, which is why the park is opposite the building rather than a drive away, and why the building's north outlook is over parkland and water rather than over a neighbouring roof.
The park carries a ten-foot-wide concrete trail, the Sandy Reed Memorial Trail, and a separate five-foot asphalt path for walkers and joggers, the Kinder Footpath. Among its named destinations are Lost Lake, The Water Works visitor centre on Sabine Street, the Johnny Steele Dog Park, the Barbara Fish Daniel Nature Play Area and Picnic Pavilion, and Eleanor Tinsley Park, with bike and kayak rentals and public artworks along its length.
For an owner the practical effect is that outdoor space is not confined to the building's own terrace, which is a materially different proposition from a tower whose green space stops at its property line. It has a second consequence worth stating plainly: the bayou is the drainage way for this part of the city, and any buyer should treat flood diligence at this address as a real step rather than a formality. This site does not publish a flood zone for the building, because it has not been able to retrieve one from the federal map service; the current map, and an elevation certificate if one exists, are what to ask for.
What does it cost to buy at The Royalton?
The median sale price across homes sold since February 2026 is $466,062, at an average of $348 per square foot, with 9 homes sold in the trailing twelve months out of the 253 in the building. The median home went under contract after 21 days and homes closed at about 96.8 percent of asking. Those figures come from the market-statistics feed behind this site and were computed as of August 2026.
What they describe is a price band rather than a trend. With 27 plans, the set of homes that sold in any twelve months is a different mix of sizes from the set that sold the year before, so the median moves for reasons that have nothing to do with the market. The per-square-foot figure is the more portable of the two, because it adjusts for the size mix, and it is the number to carry into a comparison with another building.
The cost of owning here is a separate question from the cost of buying, and at a full-service building it is the one that more often decides whether a home works. The monthly assessment, how it is allocated between homes, what it covers and how it has moved over the last decade are set out on the fee page.
What can this page not tell you?
The floor plans. Twenty-seven plans is the building's defining feature and the plan set is not a public document, so this page cannot compare them, rank them by usable space, or tell you which ones read larger on paper than they live. That comparison exists in an agent's working knowledge of the building rather than in any published source, and it is the single thing most worth asking for directly.
Which floors and exposures see what. The building faces parkland to the north and the city to the east, and a home's outlook depends on its floor, its side and what has been built next to it since. No published source sets that out floor by floor, and this site will not guess at it.
The building's flood zone, its current permitting status, and the schedule of allocated interests that fixes each home's share of the common expenses. The first was not retrievable from the federal map service; the second is a live record held by the city; the third is an exhibit to the recorded declaration and is obtainable, but this site has not obtained it and will not publish a figure it has not read. Where a number matters, this site publishes the document it came from or says that it does not have one.
Questions & answers
The Royalton questions, answered
What is The Royalton?
The Royalton is a 33-story condominium tower at 3333 Allen Parkway in Houston, standing on the Allen Parkway edge of Buffalo Bayou Park. It holds 253 homes laid out across 27 one, two and three bedroom floor plans, and it runs a staffed lobby with concierge and valet.
The building opened in December 2002 as a rental tower named for its address, and became a condominium after a sale in December 2004. That history is why a search for its origins so often comes back empty: the construction record is filed under 3333 Allen Parkway, not under the name the building carries now. What separates it from the small towers elsewhere in the Inner Loop is range. Twenty-seven plans across 253 homes is a wider spread of size, layout and outlook than a building of seventy or ninety homes can offer, which is why the questions buyers ask here are about which plan and which exposure rather than whether the address suits them.
Where is The Royalton, and what is it across from?
The Royalton sits at 3333 Allen Parkway in Houston's 77019, which the market-statistics feed behind this site classes as Inner Loop. Buffalo Bayou Park runs directly opposite, along the strip between Allen Parkway and Memorial Drive, and downtown Houston stands about ten minutes away by car.
The park is the reason the address behaves differently from a tower on a commercial street. It is a 160-acre green space stretching from Shepherd Drive to Sabine Street, so the building's north outlook is over parkland and bayou rather than over a neighbouring rooftop. The drive times the operator publishes for this site put downtown at about ten minutes and the Texas Medical Center at about fifteen, and the same figures come back from the market-statistics feed. Treat both as typical weekday drives rather than guarantees; Allen Parkway is a commuter route and it does not behave the same way at eight in the morning as it does at eight at night.
How many floor plans does The Royalton have?
Twenty-seven, across one, two and three bedroom layouts, in a building of 253 homes. That is an unusually wide range for a single tower, and it is the single most useful fact about buying here: the plan matters more than the building does, because the building offers so many different ones.
The developer's own project record describes the tower as 253 one, two and three bedroom units plus four penthouses, with an average home of about 1,650 square feet. An average is not a range, and the range is what a buyer needs. Two homes of the same stated size here can differ in how much of that size is usable, because a plan's shape, its window wall and where its corridors and closets fall decide how much of the floor area is living space. This site cannot publish a plan-by-plan comparison yet: the plan set is not a public document, and it is the one piece of building information most worth asking an agent for directly.
When was The Royalton built, and why do sources disagree?
Because the building has three plausible start dates and different publishers picked different ones. Construction began in October 2001 and the building was complete in December 2002 according to the developer's own project record. The condominium came later, after a sale in December 2004, and a widely cited building page gives the year as 2003.
None of the three is wrong; they answer different questions. The developer records when the structure was finished. The 2003 figure is the year the tower was in service as a rental building. The 2004 date is when it became a condominium regime, which is the date that matters for the declaration, the association and every document a buyer of a unit here will actually be handed. A trade report on the 2022 flooding described it as an 18-year-old building, which counts from the conversion. When a source gives you a single year for this address, it is worth knowing which of the three it means.
Who developed and designed The Royalton?
The tower was developed by Simmons Vedder Partners, with The Steinberg Design Collaborative and Ambrose McEnany & House as its architects, and was completed in December 2002. It was sold in December 2004, at 85 percent leased, to a condominium converter, and a widely cited building page names that buyer as Group LSR, a Montreal-based developer.
The two-stage history is worth holding onto, because the people who built the building and the people who created the condominium are not the same and they left different records. The construction record belongs to the first group and is filed under the address. The declaration, the association, the allocation of common expenses and the governing documents belong to the second and are filed under the condominium's name in the county's real property records. A question about how the building was put together and a question about how ownership here works have different answers and different documents behind them.
How big is The Royalton building?
That depends on which published figure you take. The developer's project record puts the building area at 417,748 square feet with an average home of about 1,650 square feet. A trade report on the 2022 flooding described the same tower as a 550,000-square-foot building. Both figures are published; they are not measuring the same thing.
A building area figure from a developer usually counts the space that was built to lease or sell. A figure quoted in a construction report often counts the whole structure, garage and back-of-house included, which on a tower with a parking podium is a large difference. Neither number tells you anything about a particular home, and dividing either one by 253 does not give you an average unit size that means anything, because the divisor and the numerator do not describe the same floor area. The developer's own average of about 1,650 square feet is the more useful of the published figures, and it is still an average across 27 plans.
What amenities does The Royalton have?
A widely cited building page lists a pool and sundeck, a fitness centre, a private theatre, a ballroom with a caterer's kitchen, a game room, a garden cocktail terrace, a business centre, guest rooms, an outdoor kitchen and storage, alongside 24-hour concierge and valet parking.
The list is longer than most buildings of this price carry, and that is the point worth understanding rather than admiring: an amenity set of this size is staff and plant, and the monthly assessment is the only thing paying for it. A staffed lobby, round-the-clock valet, a theatre and a ballroom are recurring costs whether or not a given owner uses them. That is a fair trade for many buyers and a poor one for others, and it is the honest way to read a long amenity list. Note also that the list is compiled from listing data rather than from the association, so it records what was offered at some point rather than what is staffed and open this month.
How does parking work at The Royalton?
Homes carry assigned spaces in a private garage, and the building runs valet parking as well as self parking, with valet available to guests. The garage is part of the common elements, so its upkeep is paid for out of the monthly assessment rather than billed separately to the owners who use it.
Two things a buyer should confirm on a specific home rather than on the building. First, how many spaces come with that home and whether they are assigned, deeded or licensed, because those are three different rights and only one of them travels automatically with the unit. Second, where the spaces physically are: in a 33-story tower over a podium garage, two homes with the same number of spaces can have very different daily experiences of using them. The resale certificate and the declaration are where those answers live, and both are documents a seller is required to furnish.
What is the pet policy at The Royalton?
A widely cited building page describes an open pet policy, with no restriction on the number or the weight of pets, limited to cats and dogs. The building also carries a pet run. For a high-rise this is unusually permissive, and it is a genuine differentiator for an owner with a large dog.
It is also the claim on this page most worth verifying before you rely on it, and the reason is structural rather than a doubt about the source. A pet policy is a house rule, and house rules are adopted and amended by the association's board, not fixed in the declaration. A listing field records what was true when the listing was written. If a pet is part of why this building is on your list, ask for the current rules document alongside the resale certificate rather than taking any published summary, this one included, as the operative version.
What is Buffalo Bayou Park, and how close is it to The Royalton?
It is a 160-acre green space running from Shepherd Drive to Sabine Street, between Allen Parkway and Memorial Drive. The Royalton stands on Allen Parkway inside that stretch, so the park is immediately opposite the building rather than a short drive from it.
The park carries a ten-foot-wide concrete trail, the Sandy Reed Memorial Trail, and a separate five-foot asphalt path for walkers and joggers, the Kinder Footpath. Its named destinations include Lost Lake, The Water Works visitor centre on Sabine Street, the Johnny Steele Dog Park, the Barbara Fish Daniel Nature Play Area and Eleanor Tinsley Park, with bike and kayak rentals and several public artworks along its length. For an owner here the practical effect is that the building's outdoor space is not confined to its own terrace, which is a different proposition from a tower whose green space stops at its property line.
