# Hotel Design Principles Hotel design is one of the most complex building typologies, integrating hospitality operations, guest experience, branding, building services, and commercial performance into a single building. The architect must understand room typologies, back-of-house logistics, food and beverage operations, lobby and public area design, and the service standards that define each hotel category. Every design decision impacts both guest satisfaction and operational efficiency. --- ## Table of Contents - [Hotel Classification](#hotel-classification) - [Guest Room Design](#guest-room-design) - [Floor Plate and Core Design](#floor-plate-and-core-design) - [Public Areas](#public-areas) - [Food and Beverage](#food-and-beverage) - [Back-of-House](#back-of-house) - [MEP Coordination](#mep-coordination) - [See Also](#see-also) --- ## Hotel Classification | Category | Room Size (min) | Key Features | |----------|----------------|-------------| | **Budget/Economy** | 14–18 m² | Functional, minimal services, self-check-in | | **Midscale (3-star)** | 20–26 m² | Restaurant, bar, meeting rooms, room service | | **Upper Upscale (4-star)** | 28–36 m² | Full F&B, spa/fitness, concierge, business centre | | **Luxury (5-star)** | 38–55+ m² | Multiple restaurants, spa, pool, 24hr room service, butler | | **Extended Stay** | 25–50 m² | Kitchenette, laundry, living area | | **Boutique** | Variable | Design-led, unique character, typically 20–150 keys | --- ## Guest Room Design ### Room Components | Element | Standard (4-star) | |---------|-------------------| | **Bed** | King (1800×2000mm) or twin (2× 1000×2000mm) | | **Bathroom** | Minimum 4.5 m²;
