Common questions before hiring

Meetings are on Google Meet, files travel by e-mail or WhatsApp and the design is delivered in PDF and DWG. You follow progress in plans and 3D images and approve each stage before the next. GMBC studies the rules of your city before the design begins.

Yes. The service is online, in English and Portuguese, for clients in any country. Where local authorities outside Brazil require approval, GMBC develops the design and the local technical responsibility stays with a professional licensed in your country, hired by you.

Fees are calculated from the project area, with a minimum per service, and adjusted for gated communities, number of floors and outdoor items such as a pool or outdoor kitchen. Large projects get a discount on the square metres above 250 m². To get the fee range and timeline for your case, fill in the quote request: the estimate arrives by e-mail.

A new house takes at least 20 business days up to permit drawings, plus 40 for construction drawings. An interior design project starts at 20 business days. For areas above 150 m², add 2 business days for every 20 m². Review time by city authorities and homeowner associations is outside GMBC's control and is not included.

Up to two revision rounds during concept and schematic design, which is when the big decisions are made. After the schematic design is approved, changes to the brief are quoted separately.

For interiors and renovations, we send a simple guide for measurements and photos. If you have a floor plan of the property, it becomes the base. If you prefer, you can hire a survey from a professional in your own city, and GMBC will tell you what to ask for.

For a new house: the plot's documents and land survey, and references of what you like. For interiors: a floor plan or measurements, photos and a list of what stays. We ask for the exact list after the first meeting.

Engineering designs (structure, plumbing, electrical), fees and filing with public authorities, reports, land survey and soil tests, purchase of furniture and materials, and technical responsibility for the construction work. Each service lists its limits on the services page.

From abroad, by international bank transfer. In Brazil, by PIX or bank transfer to GMBC Consultoria LTDA, with an invoice. Payment is split into instalments tied to deliveries, and paying in full upfront gives a 10% discount. The exact terms come in the proposal.

Yes, for properties in Brazil and through online service: feasibility study, permit drawings, RRT and responses to review comments. Filing is done by you or an agent, with our guidance. See the stages under legalisation and feasibility.
