We translate energy and regulatory requirements into real gains in value, comfort and brand. No exposed conduits, no improvised plant, and no compromise on the aesthetics you bought the property for.
Decarbonisation stopped being a regulatory conversation and became a valuation variable. A high-end property with a poor envelope loses value, loses comfort and gets more expensive to run every year.
We work on villas, landmark buildings and boutique hotels alongside technical partners — MEP engineering, energy assessors and heritage specialists — to bring the asset close to minimal consumption without degrading a single inch of its character.
Internal or external insulation, thermal bridges, roofs and high-performance joinery with profiles that respect the building's language.
Replacing fossil boilers with air- or ground-source heat pumps, radiant floors for heating and cooling, and genuine room-by-room zoning.
Mechanical ventilation with heat recovery, filtration and CO₂ and humidity control, integrated with no visible access panels.
Architecturally integrated photovoltaics, batteries, load management and EV charging.
Thermography, blower door, bill analysis and a real study of the envelope. We do not propose equipment until we know where the energy is going.
In listed buildings we work from the inside with reversible solutions and a technical report supporting the planning application.
Ducts, grilles, units and access panels are resolved at design stage, not on site. That is the difference between an efficient house and an efficient house that is also beautiful.
Every measure is presented with cost, estimated saving, energy rating jump and payback period.
Current condition, phased improvement scenarios and how they fit available grants and tax deductions.
Architecture, interiors and engineering in a single document, with closed specification and construction details.
Contractor and installer comparison, coordination with assessors and management of the technical documentation.
Site supervision, airtightness testing, commissioning and post-occupancy measurement to confirm what was promised.
Design fees plus a coordination fee for technical partners. Construction investment depends on the condition of the asset.
| Service | Indicative range |
|---|---|
| Energy audit and roadmap | €3,500 – €9,000 |
| Integrated retrofit design | 6 – 12% of construction budget |
| Technical partner coordination | 3 – 5% of services budget |
| Site supervision and verification | Scope dependent — tailored quote |
Yes. You work from the inside, with reversible solutions and a report justifying every intervention to the heritage authority. We have done it in Eixample buildings and in country estates.
In an untouched 1970s villa, reductions of 50 to 70% are common when you combine envelope, heat pumps and ventilation with heat recovery.
There are energy retrofit grant schemes and income tax deductions in Spain. We prepare the technical documentation together with the energy assessor.
Yes, and it usually should be. We set a roadmap prioritised by return and by disruption so you do not have to empty the house at once.
If you own a villa, a landmark building or a boutique hotel with high running costs, start with the diagnosis. Book a thirty-minute video call.
