The district in Wuhan with the most expensive houses is typically the Wuchang District. This area is known for its historical significance, vibrant commercial activity, and proximity to key landmarks, which contribute to its high real estate values. According to data from the Wuhan Real Estate Regulatory Bureau, the average price per square meter in Wuchang District reached approximately 18,000 RMB in 2023, significantly higher than the city's average.

The high real estate prices in Wuchang District can be attributed to several factors. Firstly, the district is home to the famous Yellow Crane Tower, a UNESCO World Heritage site, and the Wuchang Fort, which attract both domestic and international tourists. This tourist appeal drives demand for properties in the area, pushing prices upwards. Additionally, Wuchang is a central business district with a concentration of high-end office buildings, shopping malls, and restaurants, making it a prime location for professionals and investors.

Furthermore, the transportation infrastructure in Wuchang is exceptional. The district is well-connected by major highways, the Wuhan Metro, and is a short distance from the Wuhan Tianhe International Airport. This accessibility makes Wuchang an attractive option for those seeking a convenient lifestyle. The presence of prestigious educational institutions, such as Wuhan University, also contributes to the area's appeal, as families are willing to pay a premium for properties in close proximity to quality education.

In contrast, districts like Qiaokou and Hongshan, while still desirable, have lower average house prices due to factors such as less tourist activity and a slightly less central location. Qiaokou, for instance, has an average price per square meter of around 14,000 RMB, and Hongshan around 15,000 RMB, according to the same data source.

It is important to note that real estate markets are dynamic, and prices can fluctuate based on economic conditions, government policies, and market demand. However, as of the latest available data, Wuchang District remains the district in Wuhan with the most expensive houses.
