The size of a lobby area depends on several factors, and consulting an Interior Designer in Greater Noida can help determine the optimal dimensions. Consider the purpose of the lobby, whether it's for a residential building, office, or hotel. For residential buildings, a spacious lobby that accommodates seating areas and reception counters is ideal for welcoming guests. In commercial spaces like offices or hotels, the lobby size should allow for smooth traffic flow, comfortable waiting areas, and space for amenities like concierge desks or seating clusters. Balancing functionality with aesthetics is key to creating an inviting and functional lobby area.
