PROJECT TITLE: PROPOSED 2-STOREY RESIDENTIAL BUILDING

LOCATION: BRGY, BALATONG, LAOAG CITY, ILOCOS NORTE

OCCUPANCY CATEGORY: STANDARD OCCUPANCY STRUCTURES

BUILDING STRUCTURAL SYSTEM: MOMENT RESISTING FRAME SYSTEMS

– SPECIAL REINFORCE CONCRETE MF’S

PROJECT DETAILS:

This project entails designing and constructing a two-story, 140 square meter

residential structure that will offer a practical, cozy, and visually pleasing comfortable

living area. The building incorporates glass and other contemporary architectural

elements. walls, large glass windows for natural light, and a large patio outside as

well as a large carport and porch. The ground level of the residence has a communal

living area. with a study space and individual bedrooms on the upper floor.
