How to optimize your budget?

Your budget is tight and you don't know how to extend your detached house to the desired area?

Here are some tips to lower the score.

Check your quote

Start by asking for several quotes for your expansion work from various professional craftsmen certified RGE (Recognized Guarantor of the Environment) to make an informed choice.

Ask them for a detailed estimate, item by item, to determine what seems essential to you and what arbitration is possible.

Also compare providers.

Choose more economical materials

Brick or cinder block are the most economical construction solutions to create an extension and enlarge the house.

Wood is a safe bet for building an extension.

It is an environmentally friendly, durable and very strong material.

Compromise on the target area

If this is an option, you may need to build smaller than planned to reduce your budget.

Opt for a flat roof

The flat roof is the most economical, because it does not require the laying of a frame.

Everything will depend on the type of construction you are considering (house extension, construction of a garage, etc.).

Take advantage of renovation grants

Development of attics, extension adjoining the house, creation of verandas, etc.

What financial aid can you benefit from?

  • The ANAH

    and the "Habiter Mieux" program allocates aid (according to eligibility criteria) for the creation of outbuildings, the renovation of the heating system, insulation work or to fit out attics or cellars.

  • Ma Prime Renov

    ': this is an energy renovation premium that can be considered for the development of attics, for example, if you add insulation work to your project.

  • The zero rate loan

    (or PTZ) can be granted to families with modest incomes for the creation of new living spaces or additional areas such as a garage, a terrace, a balcony or a basement.

Do not hesitate to contact the various organizations such as Anil and Adil.

You can also benefit from aid from local authorities for your home improvement work: find out from the Regional Council or the Renovation Info Service Point in your department.

What are the cheapest home extensions?

The rectangular shaped extension is the easiest to build.

It is less expensive than an enlargement of an atypical shape.

Converting your attic is an excellent alternative for exploiting your dormant square meters.

Build a veranda or a loggia

These two options make it possible to create an additional living room (living room, dining room, reading room, etc.) without too much work.

Building an extension attached to the house is an option that brings aesthetic value to your house and remains less expensive than some extensions (between €1,500 and €3,000 per m²).

Only downside: you have to insulate it well so as not to suffer from the cold in winter or the heat in summer.

Convert attic

It is an excellent alternative to exploit your sleeping square meters.

Of course, this development will be possible according to certain criteria: a ceiling height of at least 1.80 m to stand up, a roof slope of at least 30 degrees, the possible consolidation of the frame and good insulation.

On the budget side, plan an envelope between 900 € and 1500 € per m² for a total development of the attic.

Construction of an independent garage

Whether it is to shelter your car or to store your bicycles or garden tools, having a garage is very practical on a daily basis.

However, it is an investment.

The envelope will depend on the type of garage (independent, attached, even buried), the dimensions of the latter as well as the materials used.

Plan a budget of between €1,000 and €2,200 per m².

Be aware, however, that there are prefabricated garages from €125 per m².

Opt for the elevation of the house

This is to make an extension of your house from above.

It is a structural work site that requires the removal of the roof, insulation work, reinforcement of the structure, the creation of a staircase, etc.

Raising your house is one of the most expensive house extensions: count around €2,150 per m².

Before embarking on the creation of your extension, remember to consult the Local Urbanism Plan (PLU) of your town hall, which lists the urban planning rules to be respected in your region for all kinds of enlargements (limitation of height , type of materials, colors, mandatory administrative procedures such as prior declaration of the extension project, building permit, etc.)
