Baihetan–Jiangsu ±800 kV Ultra-High Voltage Direct Current Transmission Line Project（66 units）

Project Overview

Located at the foot of Tianmen Mountain in Wuhu, on the banks of the Yangtze River, this project enjoys a superior natural environment, nestled against the mountains and alongside the water. It is a modern office complex that seamlessly integrates power engineering functions with natural scenery. By fully leveraging the site’s natural advantages, the project combines engineering facilities with a human-centered spatial experience, creating an efficient yet high-quality working environment.
Unlike traditional power-support buildings, this project introduces architectural aesthetics and landscape design concepts to achieve a balance between functionality and environment. It not only meets the operational requirements of an ultra-high voltage (UHV) transmission project but also provides high-quality working and living spaces for staff.
The project represents a shift in modern infrastructure development—from purely function-oriented to a balanced focus on quality and user experience.

Location：Tianmenshan Area, Wuhu City, Anhui Province, China

Scope：

lMaster planning and architectural design

lConstruction of power-support office buildings
lCourtyard landscape and leisure space development
lInterior design of office areas, corridors, and meeting spaces
lIntegration of UHV transmission supporting systems

lIntegrated project delivery covering design, construction, and handover

Solution：

The project adopts a nature-integrated architectural solution, fully combining the surrounding landscape with the functional requirements of power engineering, achieving a harmonious integration between architecture and nature.

The overall design follows a pastoral architectural concept, emphasizing openness, comfort, and a strong connection to nature. The façade features a color palette of gray, white, and gold, presenting a modern, stable, and high-quality visual appearance.

Key design features include:

lSloped glass curtain wall design enhances façade layering and natural lighting
lSquare-shaped entrance hall strengthens the visual identity and spatial presence of the entry
lSpiral staircase design combines functionality with artistic expression

The project features a specially designed courtyard garden that connects to the interior through glass, bringing in natural light and scenic views to create a quiet and comfortable space for relaxation.

In response to frequent cloudy and rainy conditions and potential shading from vegetation in southern regions, large floor-to-ceiling windows are installed along both levels of the office corridors, significantly improving indoor daylighting and spatial transparency.

The conference area adopts an extended layout combined with full-height glass windows, offering expansive views and flexible usage, and can accommodate events for over 100 people.

Highlights：

lPrime natural setting: rich ecological resources with mountain and river surroundings
lSeamless integration of architecture and nature: smooth indoor-outdoor connection
lIconic design elements: curtain walls, courtyard, and spiral staircase
lHuman-centered workspace: focused on comfort and experience
lOptimized daylighting design: adapted to local climate conditions
lEfficient meeting spaces: flexible for multiple scenarios
lEnhanced corporate image: establishing a modern benchmark project

Client Value：

This project delivers a high-performance and sustainable power office environment for the client, significantly enhancing user experience and corporate image while ensuring engineering functionality.

Core values include:
lImproved employee efficiency and satisfaction
lReduced long-term operational costs through natural lighting
lA modern corporate brand image
lFuture-ready design with strong scalability
lIntegration with green and sustainable development principles

The project successfully integrates engineering functionality with architectural quality, setting a new benchmark for power-support buildings.
