I. HOTEL INTERIOR DESIGN STANDARDS:

Hotel Interior Design and Construction Standards include core elements of functionality, aesthetics, safety and comfort, in compliance with star classification standards such as TCVN 4391:2015 of Vietnam. These standards clearly specify the size and equipment of furniture (beds, cabinets, tables and chairs, ...), construction materials, lighting systems, ventilation, electricity and water, security (fire protection, fire alarm, door peephole), utilities (wifi, telephone), ... and accompanying services such as minibar, sanitary equipment. The level of detail and luxury of equipment, materials, as well as the scale of utilities will increase gradually according to the star level of the hotel, from basic in 1-star hotels to high-class and luxurious in 5-star hotels. 

A. Important factors in Hotel Interior Design standards:

1. Function:

+ Clear division of space: reception hall, waiting area, hallway, break room, restaurant, auxiliary area (storage, laundry room, duty room...), amenities such as spa, swimming pool.

+ Each area must have a minimum wide aisle : to serve the disabled (wheelchairs), and reduce traffic density between areas to avoid mutual influence (for example, meeting rooms should not share thin walls with break rooms).

+ Bedroom area according to star rating: mini single room ≧ 12‑14 m² (room + bathroom) for low rating; double room or double bed ≧ 30‑35 m² room + bathroom for 4‑5 star rating. Special rooms / suites must have much larger area, with separate living area.

+ Ceiling height of bedrooms and public rooms: high-class bedrooms have ceilings ≧ 2.7-3 m to create an airy feeling; the reception hall is larger, can be from 3.5-4 m (or higher depending on the design for chandeliers and decorations).

+ Corridor: standard corridor width is not narrower than 1.2-1.4 m, 4-5 star corridors are wider to have decorative tables, decorative lighting next to the corridor, and a small lobby between rows for guests to wait.

+ Bedroom windows are large enough to take advantage of natural light. If there is a good view, open a balcony or loggia. The room must have windows that can be partially opened for natural ventilation, except for technical rooms.

+ Arrange the desk near the window (if any), with a separate desk lamp, power outlet next to it, USB port; if it is a business-oriented room, there should be a large desk, separate lighting, and international sockets.

+ The bathroom in the bedroom must have a sink/multiple sinks if the room is large, shower + bathtub (4-5 star room), large mirror, anti-fog mirror, hair dryer, high-quality amenities, doormat, enough robe hangers.

2. Aesthetics:

+ Consistent Design Style: From the lobby to the bedroom to the amenities. For example, if the design is modern (minimal), the furniture has sharp lines, straight lines, and minimal details; if the design is neoclassical, it needs curves, moldings, materials such as stone, carved wood, and warm yellow light.

+ Color: Main color is light - neutral (white, beige, light gray) to create a clean, bright feeling; secondary color is accent (bold or brand color) to create an impression. Light must coordinate with wall color/material so that the blue/negative light does not destroy the friendly feeling.

+ Decoration: Wall paintings, decorative lights, local artworks, trees, local materials if available (wood, bamboo, stone) to create a local mark.

+ Surface finishing materials: Floor, ceiling, wall; choose glossy or matte anti-slip stone tiles in public areas; in the bedroom, wooden floors or high-quality industrial wood materials, soft carpets (if any) next to the bed to keep guests' feet from getting cold; room doors made of thick wood or alloy + soundproofing; door handles and hinges must be of high quality.

+ Emergency lighting system : For corridors, stairs, fire exits; clear and illuminated signs in power outage conditions.

+ Noise-proof standards : Main door, soundproof windows; partition between bedroom and restaurant, meeting room must be soundproof; floor of room above/next to room must not vibrate.

  II. NOTES WHEN DESIGNING HOTEL INTERIOR:

1. Identify the target customers:

+ International guests: Need international amenities (international sockets, equipment instructions, international standard amenities), culturally appropriate decor, cleanliness (extremely clean, standard room service), illustrated language (signage, menu, catalog).

+ Family / group guests: There are connecting rooms or larger suites; many common facilities; there are chairs and small tables in the room, convenient for communal activities; the room has a small living area.

2. Choose Style and Color:

+ The Hotel Interior Design style should be consistent with the overall architecture: If the exterior architecture is in the French classical style, the interior should have moldings and soft details; if the architecture is modern, the interior should be simple, with materials such as glass, light metal, neutral colors, and minimalist design.

+ Main color : Light paint, light walls + borders, lobby with brand color/ accent color (logo color). Use warm yellow or warm white light to create a comfortable feeling, avoid strong blue-white LED light in the bedroom.

+ Combine secondary colors/sub-materials: To create highlights such as decorative lights, wooden borders, natural stone, small decorative objects with special colors (wood brown, copper, bronze, matte black).

3. Optimizing Space and Function:

+ Scientific floor plan design: Avoid diagonal traffic routes, straight corridors, room doors are not arranged opposite to room doors to reduce noise and unnecessary interactions.

+ Maximize usable space: Use multi-functional furniture (chairs with storage compartments, built-in cabinets, folding tables if needed), take advantage of wall space and hidden corners.

+ Take advantage of natural light: Large windows, balcony/loggia if available; design a canopy if the sun is facing the West to avoid heat; outside/inside curtains to adjust the light.

+ Neat and easy-to-clean common spaces: Corridors, restaurants, and spas use easy-to-clean, moisture-resistant materials; avoid cluttered decor in the hallways that makes it difficult to clean dust.

4. Use Natural Light and Elements:

+ Natural lighting: Arrange large windows, loggias, tempered glass doors; if there is a skylight, skylight in deep areas; avoid covering windows to reduce light.

+ Artificial lighting: Use energy-saving LED lights, indirect lighting (ceiling lights, wall panels); central lights for general lighting; separate reading lights by the bed; decorative art lighting; zoned lighting control (separate switches for table lamps, ceiling lights, decorative lights) so guests can adjust.

+ Other natural elements: Green trees in the lobby and corridor, small landscapes (plant pots, plants in hanging pots) to purify the air; use natural materials (wood, stone, bamboo) to create a warm feeling; if there is a nice view - open a balcony or loggia for guests to enjoy nature

5. Pay attention to materials and decorative details:

+ High-quality, durable materials: Wood is treated to prevent mold and termites; stone (marble, granite) must be treated to prevent water; metal is coated with anti-rust; fabric, carpet: fireproof, easy to wash, does not fade.

+ Small details make a difference: Door handles, locks, hinges, table legs - details can use brass, matte chrome, plated materials; beautifully framed mirrors; pictures with luxurious frames; decorative lamps made of glass, crystal or handmade lamps if the style suits.

+ Brand decoration: The hotel logo can be embedded in the interior (headboard, reception floor, carpet); the brand's signature color is repeated in small details (cushions, pillows, towels); signature decorative patterns if any. 

+  Surface finishing: Smooth, suitable glossy/matte paint; connect wood or stone joints to avoid gaps that can easily collect dust; the bathroom needs small, waterproof, stain-resistant, easy-to-clean grout joints.
