When it comes to building design and construction in the Philippines, there are various factors to consider, including the number of storeys a building can have. One common question that arises is whether a roof deck is considered a storey in the Philippines. In this article, we will delve into the world of building codes and regulations to provide a comprehensive answer to this question.
Understanding the Concept of a Storey
Before we dive into the specifics of roof decks, it’s essential to understand what constitutes a storey in the Philippines. According to the National Building Code of the Philippines (NBCP), a storey is defined as “that portion of a building included between the surface of any floor and the surface of the floor or roof next above it.” In simpler terms, a storey refers to a level or floor in a building that is designed for human occupancy or use.
Types of Storeys
There are several types of storeys found in buildings, including:
- Basement storey: A storey that is partially or entirely below ground level.
- Ground storey: The storey that is at or nearest to ground level.
- Upper storey: Any storey above the ground storey.
- Mezzanine storey: An intermediate storey between the main storeys of a building.
The Role of Roof Decks in Buildings
A roof deck is a flat surface on top of a building, typically made of concrete or other materials. It serves as a roof covering and provides additional space for various purposes, such as:
- Recreational activities: Roof decks can be used for outdoor recreation, such as lounging, dining, or exercising.
- Storage: Roof decks can be used for storing equipment, machinery, or other items.
- Access: Roof decks can provide access to rooftop amenities, such as gardens, pools, or helipads.
Are Roof Decks Considered a Storey?
Now, let’s address the main question: are roof decks considered a storey in the Philippines? According to the NBCP, a roof deck is not considered a storey if it is not designed for human occupancy or use. However, if the roof deck is designed for occupancy or use, it may be considered a storey.
To determine whether a roof deck is considered a storey, the following factors are considered:
- Height: If the roof deck is more than 1.5 meters above the floor below, it may be considered a storey.
- Access: If the roof deck is accessible by a stairway or elevator, it may be considered a storey.
- Occupancy: If the roof deck is designed for human occupancy or use, it may be considered a storey.
Building Code Requirements for Roof Decks
The NBCP sets out specific requirements for roof decks, including:
- Structural integrity: Roof decks must be designed and constructed to withstand various loads, including dead loads, live loads, and wind loads.
- Fire resistance: Roof decks must be made of fire-resistant materials and designed to prevent the spread of fire.
- Accessibility: Roof decks must be accessible by a stairway or elevator, and must comply with accessibility standards.
Consequences of Non-Compliance
Failure to comply with building code requirements for roof decks can result in serious consequences, including:
- Fines and penalties: Building owners or developers may be fined or penalized for non-compliance.
- Building closure: Buildings that do not comply with building code requirements may be closed until the necessary corrections are made.
- Liability: Building owners or developers may be liable for any injuries or damages caused by non-compliance.
Best Practices for Designing and Constructing Roof Decks
To ensure that roof decks are designed and constructed in compliance with building code requirements, the following best practices should be followed:
- Consult with experts: Building owners or developers should consult with architects, engineers, and contractors who are experienced in designing and constructing roof decks.
- Conduct regular inspections: Regular inspections should be conducted to ensure that the roof deck is safe and compliant with building code requirements.
- Maintain accurate records: Accurate records should be maintained of the design, construction, and maintenance of the roof deck.
Conclusion
In conclusion, whether a roof deck is considered a storey in the Philippines depends on various factors, including its height, access, and occupancy. Building owners or developers must ensure that their roof decks comply with building code requirements to avoid serious consequences. By following best practices and consulting with experts, building owners or developers can ensure that their roof decks are safe, compliant, and functional.
| Building Code Requirements | Description |
|---|---|

| Fire resistance | Rooftop decks must be made of fire-resistant materials and designed to prevent the spread of fire. |
| Accessibility | Rooftop decks must be accessible by a stairway or elevator, and must comply with accessibility standards. |
By understanding the building code requirements and best practices for designing and constructing roof decks, building owners or developers can create safe and functional spaces that meet the needs of occupants and users.
What is a roof deck and is it considered a storey in the Philippines?
A roof deck is an outdoor space on top of a building, typically used for recreational purposes such as dining, entertainment, or relaxation. In the Philippines, the classification of a roof deck as a storey is a matter of debate among architects, engineers, and building officials.
The National Building Code of the Philippines defines a storey as “that part of a building included between the surface of any floor and the surface of the floor or roof next above it.” Based on this definition, a roof deck can be considered a storey if it has a floor area and is covered by a roof. However, if the roof deck is merely an open space on top of the building without any walls or roof, it may not be considered a storey.
What are the benefits of having a roof deck in the Philippines?
Having a roof deck in the Philippines can provide several benefits, including additional outdoor space for recreation and relaxation, improved ventilation and natural lighting, and enhanced aesthetic appeal. A roof deck can also increase the value of a property and provide a unique selling point for potential buyers or renters.
In addition, a roof deck can offer stunning views of the surrounding area, especially in urban locations. It can also serve as a space for social gatherings, parties, and other events, making it an attractive feature for homeowners and building occupants.
What are the common uses of roof decks in the Philippines?
Roof decks in the Philippines are commonly used for recreational purposes such as dining, entertainment, and relaxation. They can also be used as a space for social gatherings, parties, and other events. Some building owners and occupants also use their roof decks as a space for gardening, exercise, or meditation.
In addition, roof decks can be used as a space for outdoor furniture and decor, such as sofas, tables, and planters. They can also be equipped with outdoor amenities such as grills, bars, and outdoor kitchens, making them an attractive feature for homeowners and building occupants.
What are the building codes and regulations governing roof decks in the Philippines?
The National Building Code of the Philippines governs the design, construction, and maintenance of roof decks in the country. The code requires that roof decks be designed and constructed to withstand various loads, including dead loads, live loads, and wind loads. It also requires that roof decks be equipped with railings and other safety features to prevent falls and other accidents.
In addition, the code requires that roof decks be designed and constructed to prevent water leakage and other forms of damage. Building owners and occupants are also required to maintain their roof decks regularly to ensure their safety and durability.
How much does it cost to build a roof deck in the Philippines?
