GLAS Tower: The Future of Office Spaces in Ortigas Center

Amid Ortigas Center’s established skyline of premier business addresses, GLAS Tower emerges as a forward-thinking landmark. Though construction commenced in 2016, its design was strategically refined during the global health crisis to directly address post-pandemic workplace priorities. This proactive enhancement integrated advanced air filtration systems, spacious low-density layouts, and operational flexibility—key pillars of crisis-resilient offices. Anchored by a cutting-edge glass façade, sustainable engineering, and wellness-centric features, GLAS Tower redefines modern commercial architecture in the Philippines, balancing aesthetic ambition with tomorrow’s functional demands.

A Distinct Vision in a Premier Business Hub

Located at the corner of Opal and Ruby Roads, near Topaz Road in San Antonio, Pasig City, GLAS is a 42-storey Grade-A tower with three basement levels and stands around 188 meters tall. It offers about 102,000 square meters of office space, with 1,500 square meters for retail. Developed by Green Asia Resources Corp., a boutique real estate firm founded in 2012, GLAS specializes in high-performance, design-led offices. The developer earned the Asia Pacific Property Award for Best Office Development in the Philippines (2017–2018) for GLAS and received PropertyGuru recognition for another project, Scape. Their “Design with Purpose” approach blends thoughtful architecture with sustainable technology to elevate tenant experience and neighborhood quality.

Built with Vision, Delivered with Excellence

GLAS broke ground on 5th of October 2016, marked by a time-capsule ceremony with Green Asia, Whiteport Inc., and ASYA Design, led by principal architect Albert Siy Yu. Construction began in 2017, overseen by ASYA Design, and included architecture, interior, MEP engineering, construction management, and leasing coordination. The building’s tapered glass façade adds visual drama to the skyline. It topped out in early 2021, reaching full height with a helipad and three basement levels. Arquee Construction Management led the build, and GLAS opened for leasing shortly after.

Prime Location, Elite Access

The tower occupies a prime location surrounded by offices, malls, hotels, and major transport routes. It enjoys direct frontage along Emerald Avenue, a key artery that connects to EDSA. From GLAS, commuters can easily reach the MRT-3 Ortigas Station in about five minutes on foot, while Shaw Boulevard Station is roughly a 15-minute walk away. In addition, the Ortigas-Antipolo UV Express terminal and the SM Megamall bus terminal are close by, offering convenient access to P2P and local bus services.

Retail, Lifestyle, and Wellness Proximity

Beyond its transportation access, GLAS is within walking distance of prominent commercial hubs, including The Podium, Robinsons Galleria, SM Megamall, and Shangri-La Plaza. These malls offer a wide array of dining, retail, and essential services. Onsite, the ground-floor lobby features a Starbucks and a Tealive branch for added convenience. Other nearby services such as banks, pharmacies, cinemas, courier offices, and wellness clinics further support everyday needs. For those commuting by bike, designated bicycle parking is available both onsite and along Emerald Avenue, promoting sustainable, low-carbon mobility. In terms of healthcare and safety, GLAS is well-positioned. Nearby medical facilities include SuperCare Clinic, Makati Medical Center, and The Medical City Ortigas, all located within 1 to 1.5 kilometers. The Eastern Police District Annex and Fire District IV Headquarters are also situated close by, enhancing security and emergency response coverage.

A Smart Designed Office Tower for a Smarter Generation

When it comes to architectural and technological excellence, GLAS stands out in multiple ways. It is the first tower in the Philippines to feature a double-glazed, triple Low-E glass façade, which maximizes natural daylight while minimizing heat gain. Its gem-inspired tapered form, accented with diamond frit patterns, helps control sun glare and gives the tower a distinct presence on the skyline. Each floor offers approximately 2,000 square meters of column-free space with 4-meter ceiling heights, providing flexibility and openness for various office layouts.

Inside, the building continues to impress. A luxurious three-story lobby showcases 8.5-meter ceilings, marble and stone finishes, and an impressive 6 × 5-meter indoor LED screen. This screen now features immersive 3D digital art installations created by Filipino artists, transforming the entry space into a gallery-like experience.

The building utilizes high-speed, destination-oriented elevators with touchless control and plasma air purification. Each office level is served by energy-efficient VRF air conditioning with occupancy sensors. Restrooms and entrances use sensor plumbing and revolving doors for hygiene and conservation. GLAS also includes rainwater harvesting systems and generous bicycle parking, promoting sustainability. These features earned LEED Platinum Core & Shell certification, reflecting excellence in environmental quality, energy efficiency, and occupant wellness.

Globally Competitive, Locally Distinguished

The integrated features shape a resilient, high-performance office environment that minimizes ecological footprint and boosts tenant experience. GLAS was recognized with the Asia Pacific Best Office Development award (2017–2018) even before topping off. It is PEZA-accredited, supporting export-oriented and multinational tenants. As a crisis-resilient tower, it earned praise during COVID-19 for its wellness-first design. Although not facilitating a merger of Makati and Ortigas offices, its forward-thinking architecture attracted multinational tenants to Ortigas and boosted the district’s prestige as a green development pioneering the next generation of CBD buildings.

More than a premium tower, GLAS embodies innovation, wellness, and sustainability. It is ideal for companies seeking a future-ready headquarters in Ortigas Center, especially those committed to environmental performance and employee well-being.
