Interior Design Sandra Calderon
For existing homes needing stylish, functional design without construction work
Do you have a house or division that does not require construction work but aims to have a well-equipped space with a stylish and functional design?
With the existing layout of the residence or space, let’s work area by area to redefine the style and create a harmonious environment. We will work on the finishes, which can be easily altered with different materials like micro cement, special wall coverings with wood, wallpaper, lighting, and equipment.
We can also change the distribution of the furniture in each space when possible or appropriate, including bathrooms and kitchens, which will allow us to have more functional and aesthetic spaces.
Interior Design Project Phases
Preliminary Study:
With the existing house plan, we will propose a new distribution of equipment and furniture. This includes a moodboard with a proposed style, color palette, and new finishes for surfaces when appropriate.
Execution Project:
We provide technical plans for furniture designed by us, along with other necessary detailed plans such as alterations to the electrical installation.
Contracts and Orders:
We coordinate essential subcontractors for the project, such as electricians and carpenters. Additionally, we handle the ordering, organizing with suppliers for delivery, reception, and verification of materials, and making claims if necessary.
On-site Supervision:
This phase involves regular site visits to ensure that the work is being carried out correctly and precisely.

“It was a pleasure working with Sandra. She was always available and had great ideas. She managed to combine different furniture pieces while maintaining harmony in the overall design. An excellent professional.”
João
“I live in the same area as Sandra, and she designed two small projects for me with great ideas, all while maintaining a smooth and friendly relationship. I also have two friends who don’t live here, and Sandra managed their projects from start to finish. If you don’t have time to research materials or visit the building site regularly, she’s the perfect choice! Sandra proposes ideas, and you just need to approve or decline. She is the bridge between you and the builder, ensuring her ideas are well implemented and presenting solutions to any issues. In the end, you’ll get an amazing house with minimal effort—except financial!”

Frequent Questions
Whats the difference between interior architecture and interior design?
Interior architecture focuses on the design and functionality of a building’s internal spaces, often involving structural changes and integrating building systems. It combines principles of architecture and interior design, emphasizing spatial organization and user experience. Interior architecture includes more technical subjects like construction methods and building codes. In contrast, interior design primarily focuses on aesthetics, furniture, color schemes, and finishes to create visually pleasing and functional environments, with less emphasis on structural changes. Interior designers typically study design principles, color theory, and materials.
Can I hire just consulting Services without implementation?
Once we have visited the site and documented the existing conditions (architectural survey and photographs of the house), we will present the necessary documentation in online or in-person meetings: preliminary study, mood board, and finishing proposals with budgets.
I have an idea of what I want, but I don’t know where to buy the materials and don’t have time to oversee the work. Can you help?
Absolutely. Once we have visited the site and documented the existing conditions (architectural survey and photographs of the house), we will incorporate your ideas into the project and coordinate the necessary work. This includes managing suppliers, purchasing materials, and handling deliveries, so everything is taken care of on our end.
