A house does not break down. It ages, and ageing can be calculated. The Building Asset Review & Long-Term Maintenance Plan tells you what your property will require, in what order, and how much to set aside each year.
We repair when things break. The boiler fails in January, the roof leaks after a storm, the quote arrives at the worst possible moment and we sign because there is no choice left.
Meanwhile, the components of a house age along known cycles. A roof covering, a boiler, a façade render, an electrical installation: each has a service life, a renewal cost and a due date. Added together, over thirty years, they represent several hundred thousand euros.
There are also the deadlines we let slip. The ten-year warranty on the last works expires and nobody thinks of the inspection that would allow it to be invoked. A year later a defect appears: the remedy is gone, the bill remains.
Since 2023, French co-owned buildings have been required to establish a multi-year works plan. No such obligation exists for individual houses. Yet they need it more: no managing agent, no general assembly, no works fund. The owner is alone, and discovers each deadline only when it arrives.
CH_G transposes this method to private property, extending it to thirty years and adding what a co-owned building does not cover: the grounds, the surroundings, the utility networks, the maintenance contracts, the current warranties and the value of the asset.
The difference between the owner who anticipates and the owner who endures is not the amount. It is the timing, and the discount a property takes when its defects accumulate.
You have owned for five, ten or twenty years. You maintain as things come up, with no overall view, and you do not know what lies ahead.
The technical due diligence said what the property was worth. The asset review says what it will require.
Before a sale or a transfer: a complete technical file, a documented history and an up-to-date maintenance plan are worth more than a blind negotiation.
Your property is in France, you are not. The plan tells you what to undertake, when, and for what amount, without having to be on site.
01
Plans, invoices, warranties, maintenance contracts, existing surveys, works history. Everything that exists is read before the visit.
02
Cadastre, local planning rules, easements, natural and technological risks. Every data point is sourced and dated.
03
Complete, non-destructive architectural visit, from basement to roof: interiors, façades, grounds and surroundings.
04
Systematic photographic record and aerial drone survey: roof covering, ridges, verges, flashings, upper façades. What nobody ever looks at.
05
Apparent condition, age, remaining service life, associated risk. Each item receives a priority and a horizon.
06
A thirty-year schedule, indexed amounts, a recommended annual provision.
A structured, illustrated document delivered as a PDF: presentation of the property, documents reviewed, inspection summary, observations by technical family, photographic record and drone views.
Above all it fixes a dated baseline. On the day of the visit the property is photographed, described, situated. That starting point then allows you to date the appearance of a defect, to distinguish what pre-existed from what was caused, to support an insurance claim or to hold a position with a contractor. The report does not replace a judicial expert report. It documents.
The same content, interactive and kept up to date. A personal, secure space accessible from anywhere. Alerts flag approaching deadlines: a warranty about to expire, a contract to renew, a survey to redo.
A full demonstration is given by video call, on request.
The items below appear in both formats: as a document in the report, and interactively in the client portal.
Every identified intervention carries a reference: element concerned, observation, recommended action, priority, horizon, indicative budget.
One line per item, one column per year, over thirty years. What is immediate, what can wait five or ten years.
Expenditure by main categories, major deadlines, cumulative budget, and the amount to set aside each month to absorb the plan smoothly.
What the observed defects take away from the value of the property, and what the plan restores. Indicative estimates intended for asset management purposes.
Dated and complete. The starting point against which every change is measured.
What can be improved, and what it returns: fire safety strategy and room-by-room equipment, simulation of energy improvement works with return on investment, and the other levers for reducing running costs identified on the property.
A plan established once ages like the building it describes. Works get done, prices move, new defects appear.
CH_G returns every two years: a new inspection, updated condition ratings, a revised schedule and revised amounts, an updated value trajectory. The report and the client portal are brought up to date; the history is preserved.
The update is invoiced separately and remains optional.
Advisory services excluding project management (maîtrise d’œuvre), excluding design, excluding regulated French surveys (DPE, asbestos, lead, termites), excluding formal valuation reports, excluding legal or tax advice, excluding judicial expertise. Observations are based on a visual examination of the parts accessible on the day of the visit. Amounts are orders of magnitude, excluding contractor quotations. The exact scope is defined in the letter of engagement signed before any work begins.
From €2,500
Fees established after an initial conversation, according to the floor area, the complexity of the property and the extent of the grounds.
VAT not applicable, article 293 B of the French General Tax Code.
