People who decide to renovate an apartment or buy a new home often worry about uncertainty: how long will the work take? How can I be sure the final result matches what I actually want? The answer lies in method. Working with an experienced architect isn’t just an aesthetic nicety – it’s the guarantee of technical management that turns your ideas into a dream home, without wasting time or budget.
But how does the design process actually work for a high-end property? In this guide, we’ll walk you through the process we follow at Architempore, breaking down every step and giving you a realistic timeline.
Needs assessment and space survey
Every great project begins with careful listening. The first phase of our interior design method – the preliminary phase – is the beating heart the entire project rests on. It’s not just about measuring walls; it’s about understanding how you want to live in your space.
During this phase, the designer conducts targeted site visits to the property to gather all the necessary information. This is the “discovery conversation” stage, where we define the guiding principles together: do you need a dedicated, quiet space for remote work? Do you want a dramatic open-plan layout for entertaining guests?
Timeline: The preliminary phase typically takes 1 week.
Here’s what happens during that first week of work:
- Document review: we study the property’s cadastral floor plans and related documentation.
- Preliminary survey: a precise measurement of the space, including a survey of any existing furniture you want to keep and incorporate into the new design, later transferred to paper and digital tools.
- Defining constraints: identifying load-bearing walls, plumbing drains, and any physical constraints on site that will affect the layout… and, of course, the budget!
Concept and preliminary design: vision and consistency
Once we’ve gathered the technical data, we move on to the more creative part: the interior design concept. This is where your wishes meet architectural feasibility. Our goal is to create a cohesive overall vision for every room, from the primary suite to the living area.
Timeline: The concept phase takes about 2 weeks.
At this stage, we don’t settle for a single idea. To give you maximum freedom of choice, we typically develop:
- Two layout options: different space configurations and furniture placements to show you how life could “flow” through your home.
- Two mood board options: visual collections of styles, colors, textures, and materials. A mood board is essential for testing how well different combinations work together before you commit to any purchases.
During these two weeks, we also sketch out a general cost estimate for the interior design project and set purchasing priorities. It’s an interactive phase that includes a mid-point review to fine-tune the direction based on your feedback.
Custom design starts to take shape here, turning an empty shell into a space that reflects who you are.
Final design and executive design: drawings, materials, and details
Once you’ve chosen your preferred layout and mood, we move into technical detail. The preliminary interior design evolves into the final design, where every millimeter is carefully planned so nothing is left to chance.
Timeline: Developing the final design takes about 1 month.
This is the phase where attention to detail separates amateur work from professional studio work. At Architempore, we handle:
- Executive design for interiors and systems: we define the exact location of every light fixture, outlet, and plumbing fixture. This prevents the frustration of discovering, once work has started, an outlet in the wrong spot or a light that doesn’t do the furniture justice.
- Material selection: wood-look porcelain tile or real parquet? With an eye on the budget, we make choices that are both beautiful and practical.
- Lighting design: light isn’t just functional—it’s emotional. We design lighting to create different moods depending on the time of day.
- Detailed shopping list: we select every single piece of furniture, finish, and material, and organize them into a clear, complete list.
The design deliverables (sent digitally in PDF format) also include 3D renderings. These 3D renderings are essential for letting you virtually “walk through” your future home, so you can confirm that every color and material choice is exactly what you wanted.
We include two rounds of revisions during this phase to make sure every detail is just right.
Real timelines for an interior design project: what to expect
One of the most common mistakes is underestimating how much time quality design work actually takes. People are often eager to start tearing things down, but starting construction without an airtight plan is a surefire recipe for delays and extra costs.
Here’s a summary of the timeline for a professional interior design project using the Architempore method:
A queste tempistiche va aggiunta la fase esecutiva, che si interseca spesso con l’inizio dei lavori. In questo lasso di tempo, l’architetto prepara gli elaborati di dettaglio per le maestranze, garantendo che l’impresa edile abbia tutte le informazioni per procedere senza esitazioni.
| Design Phase | Estimated Duration | Key Deliverables |
| Preliminary Phase | 1 week | Site survey, constraint analysis, guiding-principles conversation. |
| Concept Design | 2 weeks | 2 layouts, 2 mood boards, initial cost estimate. |
| Final Design | 1 month | Systems design, 3D renderings, shopping list, materials. Final costs. |
| Permits and Paperwork | 2 weeks or more | Building notifications, permits, and various authorizations (CILA, SCIA in Italy). |
Remember: a month well spent on design will save you three months of headaches on the job site.
The value of method over improvisation
Working with a studio that follows a rigorous method means investing in your own peace of mind. Custom design isn’t just about aesthetics – it’s about managing a complex process that involves dozens of different players.
The real added value of an experienced architect lies in coordinating with suppliers. Managing marble orders, delivery timelines for custom furniture, and the arrival of light fixtures requires a big-picture view that only a professional can provide.
That’s why the Architempore method focuses on:
- A holistic vision: we bring architecture, systems, and interior design together into a single, unified workflow.
- Budget optimization: an early, detailed cost assessment lets you know exactly where your money is going, with no surprises at the end.
- Creative direction: we follow the project from paper to reality, making sure every installation and every finish meets the expected quality standards.
Projects like Casa Ilaria in Milan or Casa Manuel show how, starting from specific needs (from a “Great Gatsby” aesthetic to minimalist Japanese order), a structured process leads to outstanding results. In both cases, the key to success was a disciplined, phase-by-phase approach that let clients enjoy the creative process without the stress of technical management.
Your home is the refuge that reflects who you are. Don’t leave its creation to chance. A methodical approach is the only way to turn a real estate investment into a work of art you can live in.
Design with us to bring a professional interior design project to life that will elevate your home.
