Nanhu No.1: terracotta rainscreen and glass facade case study
Nanhu No.1 is a mixed commercial and residential complex in Changsha, Hunan. This source-bounded case study preserves the three original project photographs and the archived record of cream terracotta panels used with glass curtain-wall areas.

What the archived project record establishes
The original post places Nanhu No.1 in Changsha and gives a total gross floor area of 112,328.50 m². A related LOPO-owned archive record identifies the owner and design institute, describes three high-rise buildings facing the Xiangjiang River, and distinguishes two residential apartment buildings from a boutique mixed-use building. Because this is a same-company source rather than independent project documentation, those names are retained as archived project facts.
The 112,328.5 m² figure describes the gross floor area of the complete development. It is not the terracotta-cladding area, a panel quantity or evidence of commercial scope.
| Field | Archived record | Evidence boundary |
|---|---|---|
| Facade materials | Cream or creamy-white terracotta panel areas combined with glass curtain-wall areas. | The record does not provide a facade-area split, system build-up or interface details. |
| Panel orientation | The supplier-authored text describes vertically installed terracotta panels on the residential buildings. | No setting-out drawing, rail direction, anchor layout or fixing detail is supplied. |
| Product model | Not stated. | Do not assign a model from a photograph, later catalogue or similar project. |
| Panel dimensions | Not stated. | Do not estimate face size, thickness or joint width from the images. |
| Cladding area / quantity | Not stated. | Total development gross floor area must not be converted into facade area or supplied quantity. |
| Construction record | Contractor, installer, support system and completion year are not stated. | Current project use requires drawings, specifications, approvals and responsible-party records. |

Facade composition visible in the archive
Terracotta and glass
The photographs show light cream panel-clad volumes beside broad glazed areas. They support a discussion of material contrast, but do not establish the glass or terracotta specifications.
Tower rhythm
Repeated floor lines, panel joints and vertical window zones organize the elevations. Exact modules, tolerances and movement-joint positions are absent from the source record.
Podium and transitions
The overall view records changes between tower, podium and entrance zones. It does not reveal brackets, cavity barriers, membranes, flashings or perimeter details.
Precedent boundary
The photographs can brief colour and elevation intent. They cannot approve structural, fire, water, thermal, acoustic, weathering or maintenance performance for another project.

What to verify before using this precedent
For a current facade package, request the exact panel model, face dimensions, thickness, colour and approved variation range; elevation setting-out and replacement strategy; panel, rail, bracket and anchor responsibility; backing wall, cavity, drainage and perimeter details; project-specific structural, fire, water and movement requirements; sample and mock-up approvals; production-lot traceability; cleaning access; quantity, delivery scope and written commercial terms.
Discuss a terracotta facade brief
Send the project location, elevations, target colour and module, preliminary area, wall-system concept, applicable requirements, delivery destination and programme. Ask for current samples, scoped technical documents and a written commercial proposal.
