Living on<\/p>\n<p>offers a number of advantages, including peace and quiet, unobstructed views<\/p>\n<p>freshness and lush greenery. These plots of land, often on slopes<\/p>\n<p>are becoming increasingly popular.<\/p>\n<p><strong>But what do you need to know before building on a sloping plot?<\/p>\n<p><\/strong><\/p>\n<p>Three important steps are recommended before building<\/p>\n<p><strong>First step: the topographical survey<\/p>\n<p><\/strong><\/p>\n<p>To obtain this, you need to call in a topographical surveyor.<\/p>\n<p>This survey describes the exact shape of the land and provides information on the percentage of<br \/>\nslope, i.e. the ratio of the height between two points on<br \/>\nthe horizontal. (slope 10%=10cm\/100cm)<\/p>\n<p>The topographical survey is used to determine the best possible location<br \/>\nconstruction.<\/p>\n<p><strong>Second stage: the geotechnical study<\/p>\n<p><\/strong><\/p>\n<p>This provides a better understanding of the terrain. For example, to determine<br \/>\nwhether it&#8217;s in an area at risk of movement. Or to detect<\/p>\n<p>cavities. It also enables us to determine the nature of the foundation soil, on the surface<br \/>\nand at depth, according to the tests previously chosen with the structural design office,<br \/>\nto determine the foundation method.<\/p>\n<p>The geotechnical study must comply with standard NF P 94 500. Which ensures that<br \/>\ncalculations and justifications concerning settlement and bearing capacity<br \/>\nin the vicinity of foundations are respected.<\/p>\n<p>These are not recommendations, but justifications to be found<br \/>\nin the reports. Beware of the types of tests recommended!<\/p>\n<p>In mainland France, a G2-AVP\/PRO report has been the minimum required<br \/>\nsince the ELAN law was introduced, and it&#8217;s up to the seller to provide it, since it provides information<br \/>\non the quality of the soil being sold. After all, the cost to the buyer is not the same depending<br \/>\non the quality of the soil.<\/p>\n<p>In Polynesia, there is as yet no law on this subject, and some professionals<br \/>\nthink it would be useful to pass one to protect those involved in<br \/>\nthe construction industry.<\/p>\n<p>Normative recommendations remain recommendations: you have to adapt<br \/>\nto the terrain, so each project requires a recommendation, and discussions<br \/>\nwith the various technicians (in particular the structural engineer and the geotechnician).<\/p>\n<p><strong>The third stage involves the expertise of the structural design office and the architect.<\/p>\n<p><\/strong><\/p>\n<p>Together, they will design the best possible framework to<br \/>\nsuit the terrain and optimize construction costs.<\/p>\n<p>The last two steps are crucial.<\/p>\n<p>And these studies, carried out by professionals, can significantly reduce the cost of insurance.<\/p>\n<p><strong>Choosing the contractor.<\/p>\n<p><\/strong><\/p>\n<p>Once you&#8217;ve completed these three steps, it&#8217;s time to choose a contractor, a decision not to<br \/>\nbe taken lightly. The price of construction per square metre should not be the<br \/>\nonly criterion for selecting a builder. Above all, be sure of his credibility,<br \/>\nreliability and experience.<\/p>\n<p>They should have a good reputation, and preferably have been working in the area<br \/>\nfor a long time. If possible, ask for references or to visit homes he<br \/>\nhas designed. Ask about his company. It&#8217;s imperative that the builder<br \/>\nhas already worked in the mountains: these sites require more<br \/>\nknowledge and practice than flat terrain.<\/p>\n<p>These recommendations may seem obvious, but we<br \/>\nstill hear unfortunate stories of people who put their trust in us and<br \/>\nwhose homes were never finished. <\/p>\n<p> Sometimes there are numerous defects that<br \/>\ncan put them at risk.<\/p>\n<p>And what should have been a lifelong dream becomes a<br \/>\nnightmare. So take your time and choose the right one.<\/p>\n<p>Once you&#8217;ve chosen your contractor, it&#8217;s time for construction. Here<\/p>\n<p>again, there are several options open to you. It all depends on your budget and<br \/>\nyour commitment to the environment.<\/p>\n<p>The different building methods for a sloping site.<\/p>\n<p>To limit additional costs, it&#8217;s advisable to adapt the house as much as possible<br \/>\nto the terrain, and not the other way around.<\/p>\n<p>\nDesign offices recommend the construction method best suited<br \/>\nto the nature of the terrain.<\/p>\n<p><strong>The first is semi-buried or recessed construction.<\/p>\n<p><\/strong><\/p>\n<p>This allows earthworks to be carried out using a single platform, and integrates the construction<br \/>\ndirectly into the ground. The advantage is insulation: less heat enters the house,<br \/>\nkeeping it cooler in hot weather.<\/p>\n<p>The main disadvantage is the blind facade, offering less natural light.<\/p>\n<p>For this type of construction, it&#8217;s important to prevent the earth from pushing against the walls<br \/>\nat the rear of the house. This allows better ventilation of the fa\u00e7ade on the mountain side<br \/>\nand, above all, significant savings on foundations.<\/p>\n<p><strong>The second type, \u201crestanque, staircase or stepped\u201d.<\/p>\n<p><\/strong><\/p>\n<p>When the slope is gentle, it enables villas to be built on variable levels<\/p>\n<p>offering more natural light. The disadvantage of this type<br \/>\nof construction is the succession of levels, which hinders good<br \/>\nair circulation.<\/p>\n<p><strong>The third type, \u201cbelvedere, on stilts\u201d.<\/p>\n<p><\/strong><\/p>\n<p>This requires the least amount of earthwork, since the aim is to build one<br \/>\nor more platforms on posts. This type of construction is more<br \/>\nsensitive to the effects of wind, and often requires<br \/>\ntwo-way the height of the piles.<\/p>\n<p>The advantages are numerous: panoramic views are unobstructed,<\/p>\n<p>lower earthwork costs. And a more<br \/>\nenvironmentally friendly<\/p>\n<p><strong>The final option: complete earthworks.<\/p>\n<p><\/strong><\/p>\n<p>This solution is the most expensive, because of the quantity of earth to be moved<br \/>\nin the backfill, which can be costly, not to mention the price of the retaining wall<br \/>\nor gunning. <\/p>\n<p> Once again, this work should be entrusted to specialists.<br \/>\nFinal tip<\/p>\n<p>If you want to ensure that the recommendations made by the experts consulted in the initial<br \/>\nstages are respected, call in a building control firm.<\/p>\n<p>This will cost you a little more initially, but will save you<br \/>\nfrom unpleasant surprises in the long run.<\/p>\n<p><em>Thanks to Andr\u00e9 Chacra, Managing Director of ACI Aifaitoraa Concipio Ing\u00e9nierie,<br \/>\nfor his insights.
