An example of a void space in building construction is the architectural furring of walls, which creates a deliberate, concealed gap between the structural wall and the finished surface.
Understanding Void Spaces in Architecture
Void spaces are essential, yet often unseen, components within a structure. They are defined as concealed areas that possess floors and are distinct from penetational openings or vertical shafts (like elevator or utility shafts). These areas serve various functional and aesthetic purposes, creating non-occupiable but intentional gaps within a building's design.
They are typically integrated into a building's design to accommodate hidden utilities, improve insulation, or enhance the architectural aesthetic by creating depth and specific forms.
Common Examples of Void Spaces
Void spaces are frequently encountered in modern construction and can take several forms, each serving a specific purpose in the building's functionality or appearance. Here are some key examples:
| Type of Void Space | Description & Purpose |
|---|---|
| Architectural Furring of Walls | This involves constructing a secondary, non-load-bearing layer or frame that creates a gap between the main structural wall and the final interior finish. It is commonly used to: - Achieve a desired aesthetic or create decorative recesses. - Hide uneven surfaces or structural elements. - Provide space for insulation, electrical wiring, plumbing, or HVAC ducts.

| Double Walls | Constructed with an intentional cavity between two distinct wall layers, double walls are often implemented to significantly enhance thermal performance, improve sound insulation, or provide a spacious channel for the extensive routing of utilities. The void between the walls contributes to these functional benefits. |
| Column Bracing | When structural columns are enclosed for aesthetic reasons, fire protection, or to achieve a specific architectural profile, the space created around the actual structural support becomes a void. This often results in a larger, finished column appearance that conceals the underlying, essential structural element. |
| False Columns | These are decorative architectural features that are not designed to bear structural loads. False columns can be built around existing structures to alter their appearance or stand alone purely for visual impact, often concealing vertical conduits or adding architectural depth to a space. |
| Facades | In certain building designs, the exterior cladding or facade system is intentionally offset from the primary structural wall, creating a ventilated void or cavity. This gap is crucial for managing moisture, facilitating air circulation, enhancing the building's aesthetic depth, and discreetly concealing insulation layers or building services.

Key Characteristics of Void Spaces
Understanding the distinguishing features of void spaces helps in identifying their role within a building:
- Presence of Floors: Unlike open shafts that span vertically through multiple levels, void spaces typically have a definable "floor" or base within their extent, even if that floor is not designed for occupancy.
- Not Penetrations or Shafts: They are distinct from simple holes (penetrations) through a surface or large, multi-story vertical openings (shafts) meant for specific services like elevators or ventilation.
- Architectural or Functional Intent: These spaces are generally created with a specific purpose, whether for design aesthetics, concealment of utilities, or to improve building performance (e.g., insulation, soundproofing).
- Often Concealed: By nature, void spaces are frequently hidden from plain view, contributing to the clean and finished appearance of a building's interior or exterior.
