Casarão Azul is a historic house in Planaltina, an administrative region of Brazil’s Federal District. Its Portuguese name means “Blue Mansion.” Researchers connect the house to Dr. Hosannah de Campos Guimarães, a physician who later held senior public offices. Studies describe adobe walls, a fired-brick front, and signs that the house was built in more than one stage.
Its exact age is still debated. One university study dates the property to around 1921. Architectural research dates its brick façade to 1926. Those two years may describe different parts of the same building.
The name is not unique, so a search for “casarao azul” can bring up several places. Vacation rentals in Paraty, Doutor Pedrinho, and Salvador use similar names. This article covers the historic house in Planaltina: where it stands, how it was built, who is tied to it, and what is known about its status today.
What Is Casarão Azul?
Casarão Azul is a historic residence in Planaltina, in Brazil’s Federal District (Distrito Federal). In Portuguese, casarão means a large house, and azul means blue. In Planaltina, the name points to one specific building on Avenida Salvador Coelho.
Academic research describes the house as the former home of Dr. Hosannah Guimarães. The same research ties the building to his medical consultations. The house also draws attention for its mixed building materials and a façade that has changed over time.
Some claims about the house are well supported, and others rest on local memory. Its link to Dr. Hosannah appears in academic work. The idea that it once served as a hospital comes from local accounts, so it needs more careful wording, as explained below.
Where Is Casarão Azul Located?
The historic house stands at Avenida Salvador Coelho, Quadra 57, Lote 141, in Planaltina, Federal District, Brazil. This address comes from a 2023 University of Brasília study. It also helps separate this house from other places named Casarão Azul.
The house lies in Planaltina’s older district, known as the Setor Tradicional, or Traditional Sector. This area has historic streets, public squares, and older buildings. Planaltina has a history that goes back well before Brasília became Brazil’s capital in 1960.
An address does not tell you whether a building is open to the public. The sources reviewed for this article do not say that the house is a museum or offers tours. Anyone planning a visit should check access with a reliable local source first.
The History of Casarão Azul
Why Sources Give Different Dates
Two dates appear in the research. A University of Brasília study places the house at around 1921. An architectural study dates the brick façade to 1926.
These dates do not have to conflict. A house can get a new front, a veranda, or extra rooms years after it is first built. So the age of the façade does not always match the age of the house.
The careful reading is that the house dates to the early 20th century, and its brick front dates to 1926. Researchers have studied the order in which the main house, façade, veranda, and southern annex were built. Until that order is settled, no single year should stand as the date of the whole house.
Casarão Azul and Old Planaltina
Planaltina’s old center feels different from the planned capital. It has older streets, squares, and homes. An August 18, 2011 report from the Federal District’s Legislative Chamber named the blue house, São Sebastião Church, and the Historical and Artistic Museum as part of Planaltina’s historic identity.
The house matters because of its age, its changing architecture, and the people tied to it. The sources do not show that it was built to serve Brasília’s construction. It is better described as part of Planaltina’s own story.
Casarão Azul Architecture and Building Materials
Architectural research gives a concrete picture of the house. It describes a mix of older building methods and a front with a different style. Together, these details say more about the building than its color does.
Adobe Walls and a Brick Façade
Researchers found fired brick in the front façade and adobe in most of the rest of the structure. Adobe is a block made from earth, usually soil mixed with water. Fired brick is clay that has been shaped and hardened by heat.
The study places this mix in a wider shift across central Brazil. Builders there were using more fired brick, but adobe was still common. The study treats the main house and the façade as separate parts, and it does not claim that every wall has been checked for the same material.
A Neoclassical Front
Architectural research describes the façade as neoclassical. This style draws on ancient Greek and Roman forms. It often uses balanced proportions and orderly, formal details.
The façade matters because it shapes how the house looks from the street. A new front can change a building’s look without changing the age of what stands behind it. A single photo shows only one moment, so it cannot explain the whole history of the structure.
Interior Layout
The architectural plan identifies a corridor, a veranda, storage rooms, service areas, a kitchen, and covered outdoor space. This layout reads like a home built for daily use. A veranda gives a covered space between inside and outside, and service rooms support household chores.
The plan shows which spaces existed. It does not prove how each room was used over the years. For that reason, this article describes the layout without assigning set roles to rooms.
How Casarão Azul Has Changed Over Time
The house looks different in different records. A university study includes a 1991 photograph of the façade. Later research tracks changes to the façade and its annexes between 2012 and 2023, including changes in color.
Three parts of the house’s story need to stay separate:
- Original structure: Research dates it to around 1921.
- Front façade: A separate architectural study dates it to 1926.
- Later changes: Research records changes to the exterior and annexes through 2023.
These records show that the house has changed, but the newest one is from 2023. None of them shows how the house looks today. A photo also captures only one moment, so anyone using images of the house should confirm the location, date, and source of each one.
Dr. Hosannah Guimarães and the Medical Connection
Hosannah de Campos Guimarães was born in Planaltina on October 31, 1905. According to his official biography, he studied medicine in Rio de Janeiro and graduated in 1929. He later served as mayor of Planaltina and held senior roles in the Goiás state government.
Academic research calls Casarão Azul his former residence and links the house to his medical consultations. That gives the building a human story as well as an architectural one. His name is spelled in more than one way across sources, including Hosanah and Hosannah. This article uses Hosannah.
A doctor’s home, a consulting room, and a hospital are different things. A physician can see patients at home without running a medical institution. Local accounts say the house may have served as a hospital for a time. A 2009 report in Correio Braziliense passed this along as oral history and noted that written records were limited.
So the evidence supports a link to Dr. Hosannah and his consultations. It does not support calling the house a formal hospital or Planaltina’s first hospital.
Why Casarão Azul Is Culturally Significant
Casarão Azul links one building to the architecture and social history of Planaltina. Its materials, façade, and recorded changes show how a local home developed. Its tie to Dr. Hosannah connects it to a man whose career moved from medicine into public office.
The house is easier to understand alongside the Traditional Sector around it. The old streets, squares, and buildings give each property context. That is why conservation there involves more than a single façade.
Residents have also taken part in this discussion. A 2009 Correio Braziliense report described residents organizing to defend local heritage and noted the poor condition of the façade at that time. That report shows concern in 2009. It does not describe the house today.
Cultural value and legal protection are two separate things. Research and community interest show why a building matters. They do not prove that it holds a legal protection status.
Preservation and Current Status
The record shows steady attention to the house. A 2009 report raised concerns about its façade. Later research documented changes between 2012 and 2023. These sources are snapshots in time.
They do not show the house’s condition today. Without recent, dated evidence, it would be wrong to call it restored, abandoned, or in any specific state of repair.
Legal status is a separate question. In 2024, the Federal District’s urban development agency, SEDUH, published a report on regularizing land in the Traditional Sector. That report covers the wider area. It does not, by itself, list Casarão Azul as an individually protected building.
Three questions are worth keeping apart:
- Is the house historically significant? Academic research and local reporting point to real architectural and local value.
- Does it have individual legal heritage protection? The sources reviewed here do not confirm it either way.
- What condition is it in now? That takes recent evidence that clearly identifies the property.
Other Places Named Casarão Azul
Several other places in Brazil use the same or a similar name. Search results show vacation rentals and venues. These are separate places, not chapters in the history of the Planaltina house.
| Location | What the name refers to |
|---|---|
| Planaltina, Federal District | Historic house associated with Dr. Hosannah Guimarães |
| Paraty, Rio de Janeiro | Vacation rental listed under the same name |
| Doutor Pedrinho, Santa Catarina | Holiday accommodation using the same or a similar name |
| Salvador, Bahia | Accommodation listed under the same or a similar name |
A booking listing says nothing about the Planaltina house’s age, design, or past use. Check the city and the type of property before applying any facts to a place. For example, a Paraty rental listing describes a holiday home, not a historic house in the Federal District.

Why Casarão Azul Matters
Casarão Azul is a distinctive piece of Planaltina’s built history. Its adobe structure, brick façade, and recorded changes offer clear architectural details. Its tie to Dr. Hosannah Guimarães links the house to the town’s medical and civic past.
The story also shows why historical claims need care. The estimated date of the house and the reported date of its façade are different claims. The medical link is documented in academic research, while possible hospital use remains a local account. Its condition today and its individual legal status still need confirmation.
For anyone searching for Casarão Azul, the first step is to find the right property. The historic house in Planaltina is not the same as the vacation rentals and venues that share its name. Once that is clear, the house offers a focused look at the architecture and memory of an older Brazilian town.
