What we design
The cellar as a destination, not a cupboard.
An underground wine cellar is the only type of cellar one visits. You descend a staircase. You open an oak door. The air changes. The light softens. In that moment, wine ceases to be a list and becomes a place. We design that place with the same rigour with which the great châteaux of the Médoc design their underground chais.

Customisation options
Each cellar is a journey underground.
We approach every cellar as an independent architectural project. We decide together on the character of the space: the artisanal severity of a Burgundian barrel vault, the domestic warmth of the Médoc, the stony minimalism of a contemporary cellar, or the classic exuberance of a Sherry bodega.
Request a personalised study- Architectural styles. Classic French, contemporary minimalist, industrial with corten steel, rural Mediterranean.
- Cinematic lighting. Focal spots on highlighted labels, wall washers, concealed skirting lighting.
- Integrated tasting area. Table for 4, 6 or 8 guests. Drawers, scenic lighting, projector for gastronomic cinema.
- Sculptural staircase. With designed access: floating treads, corten steel balustrade, lateral lighting.
- Remote control. Mobile app with historical temperature and humidity graphs, configurable alerts, access control.

Frequently asked questions
About underground wine cellars.
Can any basement serve as an underground wine cellar?
Almost always yes. We assess structure, moisture, ventilation and existing insulation. In most cases the basement already provides natural thermal inertia that saves energy and stabilises the climate. Where there is rising damp, we waterproof the space beforehand.
How much space is required?
From 6 m² for a cellar of 1,000 bottles with minimal passage space, up to 40–50 m² for 8,000 bottles with a full tasting area. We also design under staircases, technical risers or storage rooms.
What keeps the temperature stable?
The thermal inertia of the ground maintains a very stable base temperature throughout the year. We add a support climate system (usually a low-power anti-vibration unit) that compensates for peaks and maintains optimum humidity.
Does it include a tasting area?
Yes, where space permits. We integrate a solid oak tasting table, dimmable focal lighting, drawers for glasses and accessories, and optionally a service refrigerator. We transform the cellar into the most intimate social space in the home.
What temperature does an underground wine cellar maintain?
Target: 14°C ±0.5°C for long-ageing. From 3–4 metres depth the ground naturally holds 11–14°C year-round, reducing the energy load on the mechanical climate system by 60–70 % compared to an above-ground installation. Multi-temperature configurations (5–18°C) available.
What waterproofing is used in an underground wine cellar?
EPDM membrane on external structural walls, combined with perimeter drainage and a safety sump with automatic pump. In basements with active rising damp, crystalline waterproofing is injected into the slab first. We provide a full waterproofing warranty before any cellar lining goes in.
How is humidity controlled in an underground wine cellar?
Active ultrasonic humidification with demineralised water maintains 60–70 % RH. High-precision capacitive sensors at two or three control heights feed the digital climate controller. Remote monitoring via mobile app with history graphs and deviation alerts.
What is the capacity range for underground wine cellars?
From 1,000 to 8,000 bottles in a single space, up to 12,000 with double-height modular structures. Compact under-staircase designs from 300 bottles (from 3 m²) also available.
Do I need planning permission for an underground wine cellar?
Converting an existing basement without structural intervention typically requires no permission. Civil excavation to create a new underground space requires a building permit signed by a registered architect. We provide complete technical documentation for permit applications.
What is the best way to commission an underground wine cellar?
Begin with the basement floor plan and ceiling height, waterproofing state, target bottle capacity, tasting area requirements and completion date. Joan Serrate, with over 30 years of experience and references including Hotel Arts Barcelona and Hesperia Tower, responds within 48 hours. Technical site visit at no cost.
What architectural styles are available for an underground wine cellar?
Classic Burgundian barrel vault with exposed stone and carved oak racks; contemporary minimalist with microcement and corten steel; rural Mediterranean with terracotta and tadelakt; industrial with oxidised steel and slate. Every project is designed from scratch around the owner's aesthetic and the space's existing character.
What anti-vibration measures are used in an underground wine cellar?
Compressor placed in a separate technical enclosure outside the cellar, with refrigerant piping through decoupled conduits with EPDM vibration absorbers. Internal noise maintained below 35 dB and vibration at rack level below 50 Hz to prevent premature sedimentation of aged wines.
