Soil
first.

Every project starts with knowing the land: its soil, investigated by our geotechnical engineers, and its rules, checked by our urban planners. A standard handed down over two generations.

A safe plot, on the ground and on paper
As urban planners, we check the planning regulations and land-title status of your plot: you know what can be built before you invest.
A named point of contact
Their name, phone number and email from day one.
A transparent site
Photo and video reports, payments tied to verified progress.
Calculations handed over
Your design calculations and the standard applied, no black box.
Independent control
We never inspect works that we carry out ourselves.
Building for the long term
Structures designed for today's and tomorrow's climate: wind, rain, heat, water, energy.

TESTIMONIAL

Since 2017, I have worked with the leadership of FANAMBINANTSOA on many fronts: technical support, assistance, public-private partnership, advice, and even the preparation of specific applications for national and international partnerships.

Every collaboration has been highly satisfactory, and always rewarding.

Anjeva has placed its trust in FANAMBINANTSOA, and always will.

Building permits: from authorisation to anticipation

APUM panel · International Housing Fair · CCI Ivato, Antananarivo

Invited on behalf of urban professionals, Hajaharivelo Lionel ANDRIANANTENAINA, our CEO and past president of APUM, presented a proposal to simplify building permits in Greater Antananarivo: plan neighbourhoods before they are built, rather than chasing the city.

  • A pilot zone with a predefined layout: roads, drainage, land reserved for public facilities, and a geotechnical and hydrological study carried out once for the whole zone.
  • Standard house designs approved by a multidisciplinary committee, with foundations suited to each soil class, compliant with the 2019 Standard.
  • A simplified permit based on a declaration of compliance, with a target processing time of 7 to 15 days, and inspections redeployed to building sites.

Frequently asked questions

Why start with a soil investigation?
Because foundations depend on the ground. An investigation beforehand avoids cost overruns and cracks later on.
How do I know what I can build on my plot?
Our urban planners check the planning regulations that apply to your plot and its land-title status. You know what is allowed, and what is not, before buying or starting the design.
Can I take just part of a package?
Yes. Every package is modular, and every service is also available à la carte.
How can I follow my building site from abroad?
Through regular photo and video reports, a monthly video call, and payments tied to verified stages.
How much does a service cost?
Our prices depend on the service requested and its duration: a soil investigation, site supervision and a turnkey build are not priced the same way. After a first conversation about your needs, we provide a detailed, item-by-item quote.
Which payment methods do you accept?
Cash, cheque, bank transfer, including from abroad, and mobile money. For construction work, payments follow a schedule tied to verified progress.
Are your services guaranteed?
Yes, depending on the offer, and the guarantee terms are written into the contract. For example, a study is guaranteed when it comes with a monitoring and inspection assignment: we then check that our recommendations are actually applied on site. Without that monitoring, the guarantee is partial, depending on how the works are carried out and monitored.
How long does a project take?
It depends on the size of the project, the site and the permits required. Every quote includes a detailed, step-by-step schedule.
Do you work outside Antananarivo?
Yes. We work in every region of Madagascar, and internationally too: our leadership team has already delivered projects in Burkina Faso, Senegal and the Comoros. Costs related to distance are set out in the quote.
