What would you like to renovate?

The whole home, a single room or your business premises. In every case, designed by an architect.

Custom furniture: when the right piece doesn't exist off the shelf, we design it with the rest of the project, to fit the space and everyday use.

Turnkey

Design, permits, contractor, suppliers and works coordinated through to handover.

  • For a whole home, a single room or a commercial space.
  • Any level can be done in stages: one room now, another when the budget allows.
  • Site management can also be hired on its own, if you already have a design and a contractor.

Compare the levels of support

Why we recommend turnkey.

We bring design, permits, suppliers and works together in a single process. The proposal sets out who does each part, the stages and the agreed results, so you know from the start what is included.

  • A single point of contact
  • Permits, deadlines and responsibilities sorted before the works
  • Site visits and a final check of the finishes
  • Free first conversation and site visit

Bianca Tereza Barbosa · Founder

Hello, I'm Bianca.

My practice was shaped through independent projects and multidisciplinary teams. I have worked across homes, retail, hospitality and offices, from design to site management and follow-up. I completed a master's and a doctorate in architecture.

I also taught interior design for nearly two years and presented a TV programme about renovation. That experience made listening and clear communication central to my work.

Frequently asked questions.

The essentials before you ask for a proposal. For everything else, the first conversation is free.

Request a proposal
Can I renovate just one room?

Yes. We renovate any room on its own (bathroom, kitchen, bedroom, living room or another) without having to touch the rest of the home.

Can I hire just a consultation or just the design?

Yes. A consultation is the lightest option: recommendations to help you decide, always with a written report. With design only, you receive the complete design to get quotes and build with whoever you choose.

Can I do the works in stages?

Yes. You can start with one room and continue when the budget allows. We agree with you the order that makes most sense.

Do you work on houses?

Yes. We renovate the interiors of apartments and houses, new or old, as well as commercial spaces.

Do you design custom furniture?

Yes, when the right piece doesn't exist off the shelf. We design it with the rest of the project, to fit the space and the way you want to use it.

How much does it cost?

It depends on the scope, the size and the materials. The first conversation is free and without obligation. You then receive a proposal with the scope, stages and costs set out before we start.

Which areas do you cover?

In Greater Lisbon and nearby: Lisbon, Cascais, Oeiras, Sintra, Amadora, Loures, Odivelas, Mafra, Almada, Seixal, Sesimbra, Setúbal and neighbouring areas. If your space is elsewhere, get in touch.

What if the works need council approval?

We handle it for you. During the visit we check whether the works need a permit or prior notice; Bianca, an architect registered with the Portuguese Order of Architects, prepares the design and follows the process with the council.

How do we start?

Send a request through the form, WhatsApp or email. I reply within one working day to arrange our first conversation.

What would you like to transform?

Tell me what you'd like to renovate (your home, a room or a commercial space) and how much support you're looking for. I reply within one working day, and the first conversation is free and without obligation.
