6-Unit, 2-Storey Apartment Development | Ili Norte, San Juan, La Union

As La Union continues to experience steady growth in tourism, business, and residential demand, particularly within the municipality of San Juan, opportunities for well-planned rental housing have become increasingly valuable. Recognizing this demand, an overseas Filipino worker, has initiated the development of a six-unit, two-storey apartment building on his family-owned property in Ili Norte, San Juan, La Union.

The project was carefully planned to maximize the potential of the site while maintaining a comfortable and functional living environment for future tenants. Through efficient space planning and thoughtful design, the development optimizes the property’s capacity while preserving livability, accessibility, and adequate amenities for its residents.

Architecturally, the building adopts a clean and minimalist approach, utilizing conventional construction methodologies to ensure practicality, durability, and cost-efficiency. Sustainability features such as elevated water storage systems and solar panel provisions have also been incorporated into the design, helping reduce operational costs and promote long-term environmental responsibility.

More than just a rental property, the development serves as the first phase of a broader vision for the site, strategically planned to accommodate future expansions and enhancements as demand continues to grow.

A Vision Realized. A Destination Unveiled.

May 31, 2026 | De Sijn proudly marks the formal turnover of Solara Events Place in Brgy. Biday, San Fernando City, La Union.

What began as a vision has grown into a dynamic hospitality and events destination composed of these complementary developments: the Mattim's Staycation Units Building, featuring 10 well-appointed accommodation rooms designed for families, groups, and travelers; EcoHaven Multifunction Hall, a versatile gathering space highlighted by its mezzanine loft area; and the landmark SOLARA Events Hall, envisioned to host celebrations, corporate functions, milestones, and community gatherings. Complementing these facilities is a swimming pool amenity, providing guests with a refreshing recreational space that enhances the overall staycation and event experience.

Designed in a contemporary interpretation of Modern Filipino Architecture, the development embraces clean lines, tropical sensibilities, open gathering spaces, and a harmonious relationship between indoor and outdoor environments. The architectural language reflects both functionality and hospitality, creating spaces that are welcoming, memorable, and distinctly Filipino.

More than a collection of structures, SOLARA represents a new destination where people can stay, celebrate, connect, and create lasting memories. It introduces a fresh venue to the growing hospitality and events landscape of San Fernando City, offering spaces that cater to both intimate gatherings and larger occasions while supporting local tourism and economic activity.

Designed with purpose and built through a shared vision, SOLARA now opens its doors to families, travelers, businesses, and communities seeking a place where meaningful moments can unfold. As its facilities begin welcoming guests and hosting events, a new chapter begins, one filled with celebrations, opportunities, and stories waiting to be told.

SOLARA Event's Place is more than a venue; it is a destination built for experiences.

Today, 30 May 2026, a milestone was celebrated within the 6-Studio Unit Apartments with Café/Restaurant as it welcomed its very first gathering: a meaningful occasion marking the Client's birthday celebration, facility blessing, and renewal of vows.

More than an event, it was a moment that brought the building to life.

For De Sijn, witnessing spaces transition from drawings and construction works into places where memories are created is among the most rewarding aspects of our profession. The occasion allowed us to see the facility in its intended purpose: serving as a venue for gathering, celebration, fellowship, and everyday life.

As family and guests filled the spaces, conversations flowed through its halls, and families gathered under its roof, the true success of the project became evident: not merely in its completion, but in its functionality and the experiences it now enables.

Today, the building was not simply occupied, it was lived in, celebrated in, and made meaningful by the people it was designed for.
