Ultimately, the renovation is for your space. You have complete freedom in the direction of the project. Once you pick your expert, workshop with them. You can ask them for their opinion or advice. They may even show you previous house renovation projects for inspiration.
The contractor makes suggestions based on:
Neighbouring buildings
General environment
Natural lighting
Existing style
Space orientation
You can even choose the building materials. The expert suggests high-quality materials that fit your needs and budget.
The final decisions about your home renovation services are solely yours to make. You don't have to follow the contractor's advice, but it's there if you need it.
