They are not opposing services
Interior design and decoration are often presented as alternatives, when in reality they can be complementary phases of the same project. The most useful distinction lies less in the professional label and more in the depth of intervention the home requires.
A house may be well laid out, have suitable lighting and respond comfortably to the routines of the people living in it, yet still feel incomplete because the furniture has been selected without a common visual direction. In that case, decoration can organise the visible layer without needing to transform the underlying structure.
On the other hand, if the problem lies in awkward circulation, insufficient storage, poorly connected rooms, inadequate lighting points or a kitchen that does not respond to everyday use, changing textiles and furniture will not solve the root cause. In that case, it is better to start with an interior design project.
What an interior designer solves
An interior designer works on how the space is organised and experienced. They can study the layout, the relationship between rooms, lighting, materials, joinery, bespoke furniture and, depending on the scope of the commission, the coordination of decisions that need to be correctly transferred to the construction phase.
The work begins before choosing a final visual direction. First, the uses, proportions, circulation, light and storage requirements are analysed. These variables are then translated into a coherent proposal.
At Sebastián Bayona Studio, interior design projects are approached from this comprehensive perspective of the home, connecting layout, materials, lighting and furniture.
When changing one thing affects many others
Moving a door can change the position of the furniture. Opening up a kitchen may require revisiting lighting, storage and material transitions. Designing a bespoke wardrobe can alter circulation or solve a space that previously seemed too small.
For this reason, when several decisions are interconnected, it is advisable to address them within a single project rather than as separate solutions.
What a decorator solves
Decoration mainly works on the final expression of a space that already has a functional base. Furniture, rugs, curtains, decorative lighting, colour, art and objects can transform the perception of a home without changing its spatial organisation.
It is not a minor intervention. Good decoration works with proportion, scale, rhythm, texture and the relationship between different pieces. Choosing a sofa that is too large, a rug that is too small or lighting without hierarchy can disrupt the balance of a room even when the architecture itself is well resolved.
The studio’s decoration service makes it possible to address precisely this final layer and connect it with the personality and everyday use of the home.
When a home needs a project and renovation work
There are signs that indicate the problem lies in the underlying structure: the kitchen is disconnected from daily life, there is a lack of built-in storage, the entrance creates awkward circulation, the bedrooms do not provide enough privacy or the lighting has been designed without considering the furniture layout.
A project is also usually necessary when several rooms are going to be renovated at the same time. In that context, designing each bathroom, kitchen or joinery element separately can create inconsistencies and lead to duplicated work.
When the transformation affects the home as a whole, a complete home renovation makes it possible to coordinate every decision according to a shared logic.
When a decorative intervention may be enough
If the layout works, the installations perform properly and there are no significant storage or lighting problems, a renovation may not be necessary.
A newly completed home may simply need furniture, textiles and ambient lighting to gain proportion and character. Another property may already contain valuable pieces and require only more precise editing: removing certain elements, reorganising what is already there and completing the space with carefully selected additions.
The question is not how much you want to change visually, but whether the functional structure of the space needs to be altered.
Interior design and decoration can work together
In a comprehensive project, the boundary between the two phases becomes less important. The final furniture depends on the proportions established in the floor plan; curtains respond to light and window systems; decorative lighting works alongside technical lighting; and materials influence the choice of colours and textures.
Home furniture solutions can also combine bespoke designs with catalogue pieces. This continuity helps ensure that the home does not feel as though it has been completed in disconnected layers.
How to define the right brief
Before looking for a professional, it is useful to describe specific problems. “I want to change the living room” provides very little information. It is much more helpful to explain that there is not enough storage, that the dining table obstructs circulation, that the lighting does not work well at night or that the existing furniture is not appropriately scaled.
This diagnosis helps determine whether interior design, decoration or a combination of both is required. It also makes it possible to define from the outset what is expected from the project and which decisions will need to be coordinated.
Sebastián Bayona Studio is a residential interior design studio in Barcelona that develops interior design projects, complete renovations, furniture solutions and decoration from an integrated understanding of the home. If you are considering transforming your property and are unsure about the appropriate scope of the project, you can contact the studio to discuss your real needs before deciding on the type of intervention.
FREQUENTLY ASKED QUESTIONS
Can an interior designer also take care of the decoration?
Yes. In a comprehensive project, interior design can extend to the selection of furniture, decorative lighting, textiles and accessories in order to maintain the same logic from the layout through to the final details.
Can a decorator change the layout of a home?
It depends on the professional and technical scope of the commission. If the intervention involves changes to the layout, installations or construction work, it is advisable to approach it as an interior design project and clearly define which professionals will be responsible for each aspect.
What professional do I need for a complete renovation?
A complete renovation requires an approach capable of coordinating layout, materials, lighting, furniture and execution. An interior designer can structure these decisions and work alongside the appropriate technical professionals depending on the characteristics of the project.
When is it worth hiring only a decorator?
When the home already works well in terms of layout, installations and storage, but needs greater coherence in its furniture, colour palette, textiles, ambient lighting or decorative objects. In that case, decoration can transform the overall space without altering its underlying structure.
