An interior design project starts with what is not working at home: insufficient storage, awkward routes through a room, an impractical kitchen or a bedroom that must serve several purposes. Inspiration photographs help communicate your taste, but they do not replace a clear list of needs.
Define the service you want
Studios may use different names for their services. Ask whether the proposal covers furniture and textiles, layout, drawings, material selection, purchasing or coordination of work. A description such as “complete project” does not establish what is included.
If the proposal changes building elements or installations, ask which professionals will be involved and who will check technical requirements and any necessary permissions. Selecting finishes and carrying out construction work need different agreements.
A Madrid reference: BANNI
BANNI lists decoration and interior design services and gives its Madrid showroom address as José Ortega y Gasset, 26. It recommends booking an appointment and bringing a floor plan. Its project page describes support from planning through to after-sales service.
Use this information to frame an enquiry, rather than assuming every task is included. Request a proposal for your home and compare other studios. This guide is not a ranking and does not rely on unverified customer testimonials.
Prepare for the first meeting
- An available floor plan and indicative measurements, marking anything that needs checking.
- Photographs of each wall and the areas causing problems.
- A list of furniture and objects you wish to keep.
- How each room is used and any changes you expect over the coming years.
- A maximum budget and preferred completion date, separating essentials from optional work.
If you will remain in the property while work takes place, explain that early. Mention stairs, lifts and difficult access as well. These details matter before ordering large pieces or agreeing delivery arrangements.
Compare deliverables as well as designs
Ask for a list of drawings, proposals, samples and revisions included in the fee. Establish whether you will receive exact product references, final dimensions and a purchasing schedule. Confirm who checks that furniture fits, who places orders and who handles problems.
The quotation should distinguish design fees, products, transport, assembly, contracted work and taxes. Agree dates for decisions and a process for approving price changes. An early estimate may change when measurements or selections are still outstanding.
Should the whole home be done at once?
That depends on your budget and how you use the property. Ask about phased work and identify decisions that must be made together to avoid repeating tasks. Before replacing a sofa that fits well, also compare repair or reupholstery.
