Interior architecture and decoration: what’s included?

Does your interior architect also take care of decoration? Discover the difference between interior architecture and decoration, what’s included (plans, materials, furniture, lighting), and how we bring everything together through to the finishing touches.

We’re often asked whether our role ends once the walls are built. The answer is simple: for us, interior architecture and decoration are inseparable. Below are clear answers to the most common questions about our end-to-end approach.

Interior architecture and decoration: one continuous process

Does an interior architect handle the final decor?

Yes—absolutely. Our work goes far beyond technical drawings. We see decoration as the natural outcome of architecture: once volumes are optimized, we shape the atmosphere (color harmony, textiles, lighting, and furniture).

Do you offer bespoke furniture and joinery?

Yes—this is one of our specialties. A built-in library in a Paris apartment, under-eaves storage in a Perche longère, a high-end dressing for a villa: we design bespoke pieces perfectly proportioned to your space—and made to last.

  • Design: we draw the pieces and define uses (access, storage, ergonomics).
  • Finishes: selection of wood species, lacquers, hardware, and detailing.
  • Production: supervision of fabrication with our partner joiners.

Can you help with a shopping list and styling?

Yes. As part of a full project or an advisory mission, we build a detailed shopping list (furniture, curtains, rugs, objects) and source pieces from designers, antiques dealers, and editors so your interior doesn’t look like anyone else’s.

Do you work on decoration only, without major construction?

Yes—this is possible. For some projects, we offer interior styling missions: bringing a space back to life without removing walls—through finishes, color, lighting, and key pieces (high-end home staging).

Why choose an interior architect for decoration instead of a decorator?

The advantage is overall coherence. We have a 3D understanding of space and proportions. We anticipate how natural and artificial light interacts with textures. A sofa isn’t chosen “because it looks nice”, but because it’s right for the room— size, circulation, comfort, and visual balance.

Key takeaway: for us, decoration isn’t an “extra” at the end—it’s a structured part of the project, planned from the design phase.

Should you hire an interior architect before buying a property?

Buying a home is often a lifetime investment—Paris apartment, Perche house, or a villa on the French Riviera. Don’t leave room for doubt. We can support you before you sign to secure the investment.

1. Confirm the real potential of the property

Not all square meters are equal. Our expert eye looks beyond appearances and identifies real possibilities—and limits.

  • In Paris: opening the kitchen, reconfiguring layout, adding a second bathroom, structural constraints.
  • In Le Perche: roof structure condition, insulation, potential to convert an outbuilding into a guest house.
  • On the coast: optimizing openings, sunlight, views, indoor/outdoor flow.

2. Estimate renovation budget

This is the most critical point: many buyers underestimate construction costs. With a pre-purchase consultation, we provide a realistic budget range. It can also be a negotiation lever on the final price.

3. Anticipate technical and administrative constraints

We identify what could block or slow the project: regulations, technical constraints, and local specifics.

  • Paris: condominium rules (floors, windows, noise, working hours, access).
  • Heritage areas: local planning rules, preservation constraints, protected buildings.
Pro tip: before buying, validate three points: feasibility (structure/constraints), realistic budget, and likely timeline. This trio prevents unpleasant surprises after signing.

What you gain with an end-to-end approach

Need What we deliver
Project coherence Architecture and decoration designed together (volumes, light, proportions, materials).
Bespoke solutions Built-ins, storage, finishing details, supervised fabrication.
Controlled decoration Shopping list, sourcing, styling, color/textile/lighting harmony.
Secure a purchase Potential validation, realistic renovation budget, constraints anticipated.
Design-phase safeguard: validate a “decor package” early: materials/colors palette, lighting plan, a prioritized shopping list, and bespoke joinery. Otherwise, you end up choosing items at the last minute—when budgets drift and harmony is lost.

Key takeaways

Yes—an interior architect can (and should) handle decoration too: volumes + light + proportions + materials + furniture form one whole. That overall coherence is what prevents the “renovation went well but the interior feels unfinished” effect—and what delivers a truly complete result.
