# Museum and Gallery Design Museums and galleries are among the most demanding building types, requiring precise environmental control, flexible spatial configurations, and the orchestration of visitor experience through carefully sequenced spaces. The architect must balance the preservation needs of collections with public accessibility, create spaces that enhance the encounter with art and artefacts, and design buildings that are themselves culturally significant. --- ## Table of Contents - [Gallery Types and Proportions](#gallery-types-and-proportions) - [Lighting Design](#lighting-design) - [Climate Control](#climate-control) - [Circulation and Visitor Flow](#circulation-and-visitor-flow) - [Collection Storage](#collection-storage) - [Security](#security) - [Universal Access](#universal-access) - [Exhibition Design](#exhibition-design) - [See Also](#see-also) --- ## Gallery Types and Proportions | Gallery Type | Character | Typical Dimensions | |-------------|-----------|-------------------| | **Enfilade** | Rooms opening in sequence along an axis | 8–12m wide, 4–6m high | | **White cube** | Neutral, flexible, minimal distraction | 6–15m wide, 3.5–5m high | | **Industrial/loft** | Raw, flexible, large-scale work | 10–20m wide, 4–8m high | | **Cabinet** | Intimate rooms for small objects/works on paper | 4–6m wide, 3–3.5m high | | **Great hall** | Monumental space for large installations | 15–30m wide, 8–15m+ high | | **Sculpture court** | Open or semi-enclosed for 3D work | Variable, natural light preferred | ### Proportional Guidelines | Ratio (height:width) | Effect | |----------------------|--------| | 1:2 | Intimate, domestic scale | | 1:2.5 | Standard gallery proportion | | 1:3 | Grand gallery, spacious viewing | | 1:1 | Monumental, compressed feeling | Wall area per linear metre of hanging space is the primary driver of gallery capacity. Standard picture-hanging height: 1.5m centre line from finished floor. --- ## Lighting Design ### Natural Lighting | System | Description | Light-Sensitive Material Suitability | |--------|-------------|--------------------------------------| | **Top-lit (roof light)** | Skylights, lanterns, saw-tooth roofs | Excellent control with UV filters and louvers | | **Side-lit** | Windows on one or more walls | Difficult to control; glare risk on nearby walls | | **Clerestory** | High-level windows above eye line | Good balance of daylight without direct sun on exhibits | | **Light well** | Vertical shaft bringing light to lower floors | Indirect, diffuse light | ### Artificial Lighting | System | Application | |--------|-------------| | **Track-mounted spotlights** | Flexible accent lighting for paintings, objects | | **Wall washers** | Even illumination of hanging walls | | **Fibre optic / LED display** | In-case lighting for sensitive objects | | **Ambient uplighting** | General gallery illumination, indirect | | **Programmable LED** | Colour temperature adjustable for different exhibitions | ### Illuminance Limits (Conservation) | Material Sensitivity | Maximum Lux | Annual Exposure (lux-hours) | |---------------------|------------|---------------------------| | **Highly sensitive** (textiles, watercolours, photographs) | 50 lux | 150,000 | | **Sensitive** (oil paintings, bone, leather) | 200 lux | 480,000 | | **Insensitive** (stone, metal, ceramic, glass) | No limit | No limit | UV radiation must be filtered below 75 μW/lumen for all museum lighting.
