Their flexibility and ability to work on small projects can be advantageous for targeted renovation work, such as renovating a bathroom or installing flooring. Additionally, they may sometimes offer more competitive prices, which can be appealing for projects with a limited budget.

On the other hand, engaging an architecture firm can provide a more comprehensive and professional approach to renovation. These firms typically have a multidisciplinary team of experts capable of managing all aspects of the project, from initial design to overseeing construction. 

Their expertise can be particularly valuable for complex projects requiring structural modifications or specific designs. Furthermore, architecture firms often have established relationships with contractors and suppliers, which can ensure the quality of materials and workmanship.

Whatever your choice, be sure to obtain multiple detailed quotes and check the professionals' references before making a decision. Ultimately, the goal is to choose the option that best meets your needs and expectations for building renovation.

Furthermore, researching competitive materials and craftsmen is another way to reduce the total cost of renovation. Comparing prices and requesting multiple quotes can help find the best deals without compromising the quality of materials or services. Additionally, some contractors offer the opportunity to benefit from grants or tax credits for eco-friendly renovation work, such as energy-efficient renovations. Learning about these opportunities can help alleviate the financial burden of renovation while contributing to environmental preservation.

Finally, remaining flexible and open to adjustments during the renovation process can also lead to savings.
