Most venues that add a second bookable room budget for the shell and the floor, then discover that the bar is the part deciding whether the room actually earns. In a permanent ballroom the drinks infrastructure is invisible: a back bar built into the wall, a cool store, a glass washer with its own drain, water and waste in the right corner, and a locked cupboard for stock. A relocatable hall arrives as a weather-tight envelope and very little else. So the drinks plan is a site-services decision before it is a menu decision, settled before the first couple walks through the door.
Stand in your existing function room and count what the bar depends on: fixed shelving, chilled storage, running water, a sink, waste, glass wash with hot water and drainage, power for fridges and coffee machines, and somewhere to lock stock overnight. None of that exists in a second room on the lawn unless you build it or bring it.
The question that decides everything else is distance. If the new room sits within a short trolley run of the existing kitchen and cellar, you can run one service operation and restock during the meal. If it sits at the far end of the site, the room needs its own chillers, ice, glass and a person who does nothing else all evening. Answer that before choosing glassware, because it changes both the equipment list and the wage bill.
Where the bar sits inside the room decides the rest of the layout: near the service door for restocking, away from the top table so speeches are audible, and out of the line between the entrance and the dance floor so the queue does not block arrivals.
This is where the building itself starts to matter. One option is an expandable wedding venue that arrives on its own chassis and opens hydraulically on site, giving 96–235 m² of floor depending on model, interior height of roughly 3.8 m and above, and a B2 fire-retardant interior finish. For bar planning, three questions go to the supplier early: where a back bar and fridges can stand without overloading the floor, how power and water reach that corner, and how stock and kegs are delivered without crossing the guest route. LZM builds these units for hotels, resorts, wedding venues and event rental companies.
In most jurisdictions, selling alcohol needs either a premises licence covering the space or a temporary event notice for each date, and a structure that arrives on a trailer is not automatically treated like a brick room. Licensing officers tend to ask for capacity, layout, exit routes and sometimes structural detail.
Three practical points follow. First, ask the licensing authority in writing whether the room as sited can be covered by your existing licence or needs its own, and keep the reply. Second, consider the concession route: many venues let a licensed caterer or bar operator hold the alcohol licence and carry the risk. Third, tell your insurer what you plan to serve and where, because public liability and licensing conditions are usually reviewed together. Treat the authority's written answer as the ruling, not this article.
A drinks service fails in the forty minutes after the ceremony, not across the whole evening. Guests arrive together, they all want a drink, and a single service point turns that into a queue that reaches the top table. Revenue does not disappear; it moves to the table, where nobody is selling.
What changes throughput is dull and cheap to fix: two short service points instead of one long bar, welcome drinks poured and passed on arrival, wine already on the tables before guests sit, pre-batched drinks for the first hour, card readers that work without a signal, and enough ice and glass wash capacity to keep pace. Glass choice matters too. Real glass photographs better but breaks and needs washing; polycarbonate survives a late night but scratches. Whichever way you go, the store, the wash and the waste route all need a home in the plan before the first booking.
Send the bar position, your peak guest count, and whether you hold the licence yourself or work with a caterer — those three answers point to a footprint and a service plan. Write to [email protected], message WhatsApp: +86 186 6381 3961, or start from the model range at www.lgloader.com.
