Most delays in a custom wine cellar come from decisions that were never made, not from production itself. Locking the room dimensions, the bottle count, the shelving layout and the finish before fabrication starts removes almost all of the risk.
Measurement is the first proper step. Wall-to-wall dimensions, floor levels, ceiling height, door swing and any column or duct must be confirmed on site rather than inferred from the architectural drawing, because cellars are frequently the last room to be built.
Cooling capacity follows room volume, insulation and glass area. A glazed cellar wall can double the load compared with a solid one, so the glass specification is a cooling decision as much as a design decision.
Installation is the stage buyers underestimate. Decide early whether our engineers travel to site or a local fitter follows our drawings, and build in two weeks of float before the opening date.
