Renovations, heritage and volumes
For your renovation plans in Therwil, the official RegBL figures provide essential guidance. With 715 buildings under heritage protection, it is vital to contact the municipality early to discuss permit requirements. Regarding building volume, the median is 782.5 m3. However, please note that this figure is based on only 16 properties measured according to the SIA 416 standard, while 1894 properties use other standards or are categorized as unknown. Consequently, data coverage for volume is partial. Furthermore, no specific data regarding the renovation year is recorded, which should be considered during your project assessment.

The importance of planning
Before starting any energy renovation project, rigorous planning is essential. In Therwil, as in the rest of the canton of Basel-Landschaft, work must be considered holistically. A grant application must usually be filed before work starts to be eligible.
It is recommended to consult local professionals to assess the current condition of your walls. Good preparation helps avoid technical and budgetary surprises.
Use the RenoIndex calculator to anticipate the necessary budget before requesting detailed quotes from specialized companies in the region.
Aesthetic aspects and permits
It is crucial to check with the municipality whether your choice of materials and colors meets local standards.
A complete permit application, including precise plans, will facilitate the processing of your file by the competent authorities, avoiding unnecessary delays in your work schedule.
Optimizing renovation costs
Scaffolding is a big share of the cost : bundle facade, windows and roof. By performing this work simultaneously, you reduce the fixed costs related to site installation.
In Therwil, this approach not only saves on labor but also benefits from a more homogeneous thermal improvement. Remember to coordinate the schedule with your craftsmen to optimize the duration of the work.
Our RenoIndex estimator helps you understand the financial impact of each intervention, allowing you to prioritize the most effective expense items to maximize your total renovation investment.
The choice of insulation materials
Choosing the right insulation is crucial for the durability of your facade in Therwil. There are various options such as mineral wool, expanded polystyrene, or bio-based materials. Each material offers different thermal and acoustic performance.
In the canton of Basel-Landschaft, it is advisable to prioritize solutions that meet modern building standards. Do not hesitate to ask an expert for advice to adapt the material choice to your building's existing structure.
To get a precise idea of the budget according to the selected material, the RenoIndex calculator is your best ally.
