Interior Design Cost in Sao Paulo (2026)
Quick Answer
Estimated rangeIn São Paulo, interior design fees are commonly charged either per square metre, as a percentage of the project value, or as a fixed fee. A realistic working estimate for residential interior design in the city is roughly BRL 80-300 per m² for design-only work, with small-room consultations often around BRL 300-1,500 and full-home projects running from a few thousand reais into the tens of thousands depending on scope. Exact pricing varies sharply by designer reputation, whether architectural drawings and site visits are included, and the level of project management.
Overview
Interior design pricing in São Paulo is not tightly standardised, so most clients will receive a bespoke quotation after an initial briefing. For flats and houses, many professionals charge by floor area, especially when the brief includes layout studies, materials specification, lighting plans, joinery detailing or 3D visuals. Others prefer a fixed package for a room, or charge a percentage of the furnishing and renovation budget when the service includes procurement and site follow-up. In São Paulo, costs tend to be higher than in many other Brazilian cities because of stronger demand, a large premium property market, and the frequent use of custom joinery, imported finishes and specialist contractors. The local market also mixes two regulated professions: architects, who are overseen by CAU/BR, and interior designers/decorators, who may be trained specialists but are not licensed through the same architectural council unless they are also architects. If you are comparing quotes, check whether the fee covers measured survey, technical drawings, revisions, shopping support, contractor coordination and visits during works. Those extras can materially change the total cost even when the headline design fee looks similar.

Local Context
In São Paulo, quotations for design services are normally bespoke and may or may not mention taxes explicitly, so ask whether ISS and any other applicable taxes are included in the fee. Tipping is not standard for design services. Prices are generally higher in central and premium neighbourhoods and for high-rise apartments that require more coordination with building rules, deliveries and contractors.
These are data-informed estimate ranges, not confirmed prices.

Frequently Asked Questions
Do interior designers in São Paulo charge by hour or by project?+
Usually by project, per room or per square metre. Hourly charging is more common for consultations, shopping support or extra revisions.
Is there a call-out fee for an interior designer?+
Sometimes. Many professionals wrap the first visit into a consultation fee, while others offer a paid briefing visit that is later credited against the full project if you proceed.
Are architects and interior designers regulated in Brazil?+
Architects are regulated through CAU/BR and regional councils. Interior decorators and designers may practise without being architects, but only registered architects have the architectural regulatory framework under CAU.
Does the quoted fee usually include furniture and construction?+
No. The design fee is typically separate from contractor labour, materials, furniture and appliances unless the proposal explicitly says procurement or turnkey execution is included.
Where can I find vetted professionals in São Paulo?+
For architects, the CAU system is the key official regulator to verify registration. You can also use established Brazilian architecture and design directories or professional association listings, but always check credentials and scope carefully.
