01. What are the working phases of a construction project?
- Pre-briefing and budget estimate
- Briefing
- Site visit for dimensional survey
- Preliminary study of alterations
- Construction execution project (choice of materials, detailed drawings and bill of quantities)
- Requesting quotes from contractors
- Construction supervision
- Photographic report
02. For a home renovation budget, what documents do you request?
Usually, we ask for the land registry document (caderneta predial), land registry certificate (certidão da conservatória) and floor plans or other drawings of the existing property. The more documentation provided, the simpler the process.
03. What is the most difficult stage of a construction project?
We don't believe there is one specific hardest stage, but rather a combination of things that can sometimes be tricky to manage. For example: multiple tasks happening simultaneously, materials arriving on site, ensuring everything is executed as planned, client expectations, deadlines, mistakes... Therefore, working with good partners is essential to anticipate and resolve these challenges.
04. Do you only do the design or do you also supervise the construction?
We handle the design and, if the client wishes, we also supervise the construction. This is a service charged separately from the design, and its cost depends on the type of project, location, and the need for more or fewer hours of supervision.
05. Can you make all of a client's wishes for their home come true?
Sometimes, not all client wishes can be fulfilled, whether due to lack of space, budget, technical issues... But we always find a solution together to satisfy the client's needs and tastes.

Testimonials
Client satisfaction with the final outcome is our absolute priority.
The result was the creation of a functional, relaxing and aesthetic space.
Attention to detail and the sensitivity in understanding the 'dream' idealised by the homeowner. The ability to capture and understand — eliminating any 'noise' — what is truly wanted from a renovation. The result was the creation of a functional, relaxing and aesthetic space. And what better compliment than hearing one of the construction teams express their admiration: 'She is an architect who knows what she's doing, has great feel and it's a pleasure to work on her projects.'"
The final result is very good. And, looking back, would we work with P42 again? Absolutely!
Above all, we highlight the availability, empathy and hands-on approach throughout the entire process. Whenever it was necessary to align, discuss or clarify any matter, they were always available and the response never took long. Communication was always clear and empathetic. We also greatly value meeting deadlines. The work was always executed and communicated in a timely manner, without delays and in accordance with what had been previously defined. As for the final result, we are extremely satisfied. The materials and solutions chosen came together very well and the outcome matched our expectations.
Solutions I had never thought of, which ended up making all the difference to the final result.
Our home renovation started with a project completed in record time. Architect Luísa listened carefully to everything I wanted and incorporated my ideas, but what surprised me most were her proposals: solutions I had never thought of, which ended up making all the difference to the final result. She supervised the build from start to finish and it all went smoothly. I recommend them to anyone looking for a thoughtfully designed project and someone who brings fresh ideas to the table.
