Les facteurs qui influencent le co\u00fbt<\/h2>\n\n\n\n
1. La structure existante<\/h3>\n\n\n\n
La capacit\u00e9 portante des fondations et des murs est d\u00e9terminante. Un renforcement structurel peut repr\u00e9senter une part importante du budget.<\/p>\n\n\n\n

- Renforcement des fondations<\/li>\n\n\n\n
- Reprise en sous-\u0153uvre<\/li>\n\n\n\n
- Renforcement des murs porteurs<\/li>\n\n\n\n
- Remplacement ou modification de la charpente<\/li>\n<\/ul>\n\n\n\n
2. La surface cr\u00e9\u00e9e<\/h3>\n\n\n\n
Plus la surface est importante, plus le prix au m\u00b2 diminue. Les petites sur\u00e9l\u00e9vations (10\u201320 m\u00b2) sont proportionnellement plus co\u00fbteuses.<\/p>\n\n\n\n
3. Les mat\u00e9riaux et finitions<\/h3>\n\n\n\n
Menuiseries aluminium, isolation renforc\u00e9e, toiture plate, verri\u00e8res : ces choix influencent fortement le budget final.<\/p>\n\n\n\n
4. L\u2019acc\u00e8s au chantier<\/h3>\n\n\n\n
En zone urbaine, l\u2019acc\u00e8s difficile peut augmenter les co\u00fbts :<\/p>\n\n\n\n
