The stages of your project: our interior architecture methodology

Whether you want to renovate a Haussmann apartment in Paris, a longère in Le Perche, transform a loft, or rethink a second home, successful works depend on a rigorous methodology. We manage the entire project: design, contractor tendering, and site supervision, with teams that can be mobilized across France.

1. Site survey and initial concept: setting the foundations

It starts with a precise diagnosis. We document the existing conditions and define the scope so you avoid “grey areas” from day one.

Needs & lifestyle: uses, habits, day-to-day constraints.
Budget & constraints: structure, utilities, condominium rules, regulations.
Priorities: style, daylight, circulation, storage, key functions.

Deliverable: a first concept sketch that reveals the space’s potential and validates feasibility.

2. Detailed design (APS / APD): technical and aesthetic precision

This phase turns intent into an executable project. We build a complete reference package that every contractor will follow during the works.

What the design package includes

Plans, sections, elevations: accurate technical documents for each trade.
Materials & finishes: coherent, durable selections suited to the existing building.
3D modeling: realistic visuals to validate volumes, atmosphere, and details before site start.

Why it matters: full upfront validation drastically reduces mistakes, delays, and expensive mid-site arbitration.

3. Costing and schedule: keeping the budget under control

A calm project is a controlled project. We write a clear scope, run the contractor consultation, and secure the budget trade by trade.

Comparable quotes: offer analysis, technical consistency, key watch-outs.
Final costing: options framed, decisions made, priorities set if needed.
Provisional schedule: sequencing of trades and validation milestones.

Goal: no “surprises” caused by missing line items or unclear scopes.

4. Site supervision (project management / DET): delivering without drift

Site supervision is the most critical phase: this is when the project becomes real. We lead the execution to ensure compliance, quality, and deadlines.

How we manage the site day to day

Trade coordination: electricians, plumbers, joiners, painters, etc.
Site meetings: decisions, technical checks, removing blockers.
Quality control: compliance with the package, details, finishes, corrections if needed.
Regular reports: progress, decisions made, next steps.

Handover: final reception, snagging, and key handover aligned with the validated project.

Paris, Le Perche… and teams across France

Our organization allows us to be physically present where your projects take shape, mobilizing teams and partners depending on location and project type.

Paris & Île-de-France: urban constraints, condominium rules, logistics, access, neighbors.
Le Perche (Orne / Eure-et-Loir): heritage buildings, longères, farmhouses, character renovations.
Nationwide: primary and second homes, villas, signature projects requiring a high level of finish.

Our promise: the same level of method, control, and finishing—wherever the site is.

Commitments: what this changes for you

Commitment	Client benefit
Transparency	Controlled costing, clear scope, traceable decisions.
Method	A solid APS/APD package to avoid improvisation.
On-site supervision	Quality control, coordination, deadline management.
Peace of mind	One point of contact to handle technical surprises.

Key takeaway: clear design + controlled budget + rigorous supervision = works delivered without drift or unpleasant surprises.

Pro tip: validate a “site-ready package” before signing quotes: updated plans, materials confirmed, key technical decisions finalized, and a realistic schedule.
