Renovations, heritage and volumes
For your renovation projects in Olten, official building register figures offer vital planning insights. Regarding heritage protection, one building out of 3098 is designated as protected, meaning you must contact the municipality early to secure necessary permits. Concerning building volume, for the 1672 recorded houses, the median volume measured according to the SIA 416 standard is 1063 m3, which is essential for scaling your heating and insulation upgrades. Please be aware that data coverage is partial for both building volume and renovation year, as a significant number of properties do not have these specific details documented.

The crucial importance of the base
The quality of your terrace depends directly on its foundation. The base, whether it is a concrete slab, adjustable pedestals, or a well-compacted gravel bed, is what prevents sinking and cracking over time.
Inadequate ground preparation can lead to costly deformations. Make sure to properly drain the area to prevent water accumulation under the surface. A good base is the most cost-effective investment to ensure the longevity of your installation.
Use our RenoIndex estimator to correctly budget for your ground preparation and avoid nasty surprises during the work.
Materials and frost resistance
In our region, the climate imposes significant thermal constraints. When choosing your covering, always prioritize materials certified for frost resistance.
Natural stone pavers, porcelain tiles, or certain treated woods are excellent options to face harsh winters. A poor selection can cause your tiles to crack during the first thaw.
The porosity of the material is a key factor to consider to avoid moisture absorption. Consult the RenoIndex experts to compare the prices of various covering materials available on the market and make a durable and aesthetic choice for your home.
Regulations and permits
Rules regarding distances to property boundaries must also be scrupulously respected. Ignoring these procedures can lead to demolition orders or fines. To avoid these inconveniences, contact the local planning department.
Once your plans are approved, use our RenoIndex tool to get a reliable price range and start your work with peace of mind.
