What actually happens when an interior designer works in your house?

Interior design in your house follows a structured five-stage process: Discovery, Concept, Design & Specification, Commission, and Reveal. The designer spends time understanding your home’s architecture, your daily life, and your constraints before presenting any ideas. This approach prioritises permanence and fit over trend, ensuring the finished interior works for the people living in it rather than for display.

Why the first conversation happens in your home, not a showroom

The Discovery stage begins in your space. A designer visits to understand the room’s proportions, light, existing structure, and how you actually use it. This is not a brief meeting. At the London Embankment Apartment and the Witham Project, the studio spent time observing how natural light moved through the rooms, where furniture needed to function, and what the architectural bones could support. This groundwork prevents the common mistake of designing a beautiful interior that doesn’t fit the reality of living there.

During Discovery, the designer also talks with you about longevity. What materials will survive daily use? What colour palettes will feel right in five years, not just on the mood board? The studio asks about your routines, your storage needs, and the finishes that matter to you personally. This is the only stage where the designer gathers information; every decision that follows is rooted in what they learned here.

How a concept takes shape before any purchases are made

After Discovery, the Concept stage translates observation into direction. The designer develops a visual and material narrative that responds to your home’s character, your brief, and the constraints uncovered on site. At the Witham Project, the concept emerged from the existing architecture and the client’s preference for restraint; at the London Embankment Apartment, it reflected both the building’s period features and contemporary living patterns. A concept is not a finished design — it’s a coherent idea that all subsequent choices will support.

The Concept stage includes material and colour exploration. The designer selects finishes and palettes that will age well and support the interior’s purpose. This is where longevity begins. A reupholstered sofa keeps its original frame; wall colours are chosen for their permanence, not novelty. The studio presents the concept to you in a format you can live with and respond to — typically boards with materials, references, and colour notation. Your feedback at this point shapes everything that follows.

What happens during the detailed design and specification phase

Concept, Design & Specification is where ideas become precise instructions. The designer creates detailed drawings of layouts, elevations, and joinery. Every door, shelf, light fitting, and upholstered piece is specified by material, finish, dimension, and supplier. Nothing is left ambiguous. This stage requires deep technical knowledge: understanding how plasterboard meets existing brick, how a timber veneer will move with humidity, how electrical runs support lighting placement without compromising wall integrity. The commercial projects—Beaulieu Dental Practice, Fruittii Hair Salon, Keystones Estate Agent, and Tone at Canary Wharf—all demonstrate how thorough specification prevents on-site delays and ensures the finished space matches the intended design.

For residential interiors, this stage also includes deciding what stays and what goes. Existing elements are either retained and adapted, or removed. A radiator might be repositioned; a window frame might be restored; a redundant chimney breast might be opened up. The designer coordinates with structural engineers, building control, and specialist contractors to ensure every decision is feasible. By the end of this stage, you have a complete picture of what the interior will be, down to the finish of every surface.

How the commission phase keeps the design on track

The Commission stage is where all specified items are ordered and made. Bespoke joinery is built to drawings; upholstered pieces are made to specification; materials are sourced and scheduled for delivery. The designer manages timelines and coordinates deliveries so that everything arrives when the interior is ready for installation. This is also when unforeseen decisions arise—a material becomes unavailable, or a site condition requires a minor adjustment. The designer handles these within the agreed parameters, never reverting to off-the-shelf alternatives without your approval. Clarity from the Concept, Design & Specification stage means these decisions are rare.

Throughout Commission, the designer remains the liaison between you, makers, and installers. Progress is communicated clearly. Bespoke items are approved before final production. The schedule is protected so that installation can proceed without congestion or compromise. This stage can span weeks or months, depending on the scale and complexity of the project, but the process remains transparent and managed.

What the Reveal means and why installation is not the end

The Reveal stage is installation and handover. All elements—joinery, furniture, finishes, lighting—are installed in the sequence designed to achieve the intended effect. The designer is present to oversee quality and ensure everything is positioned and finished as specified. At the London Embankment Apartment and Witham Project, the Reveal showed how all the earlier decisions came together in the actual space, where light and proportion became real rather than drawn. This is the first moment you see the interior complete.

After installation, the designer walks through with you, explaining care and maintenance for every material and finish. A natural stone surface requires different treatment than plasterwork; upholstered pieces have specific cleaning protocols; timber veneer benefits from occasional conditioning. This knowledge ensures your interior ages well and performs as intended. The designer remains available for questions as you settle into the space. The interior is now yours to live in, but the relationship established during Discovery through Reveal means you have guidance if adjustments are needed.

How interior design in a house differs from commercial projects

Residential interiors are shaped by how you live in them every day. Unlike commercial spaces—where a dental practice or hair salon serves clients and staff in defined roles—a home must accommodate your personal routines, your belongings, your preferences, and your family’s needs. The designer works at an intimate scale, understanding not just the room but how it connects to the rest of your home. Storage, comfort, and personal expression are equally important. The studio’s residential work at London Embankment and Witham demonstrates this balance: the interiors are refined and considered, but they are unmistakably homes, not show spaces.

Residential projects also operate on your timeline and budget, not a commercial lease or turnover schedule. The designer works within your constraints, prioritising the elements that matter most to you. This might mean completing key spaces first and planning others for later. It might mean sourcing a particular material that takes longer but feels essential. The process is thorough, but it is also realistic about the fact that you live there while decisions are being made.

Common questions

How long does interior design in a house typically take?

The timeline depends on the scale and complexity of the project. Discovery can take one to two weeks. Concept, Design & Specification together usually span four to eight weeks. Commission and installation vary greatly: a single room with bespoke joinery might take two to three months total; a whole-house project can take six months or longer. The designer provides a realistic schedule during Discovery.

What should I prepare before the designer first visits?

Have a clear idea of which spaces you want to address and what you hope they will do for you. Think about how you use each room, what frustrates you about it, and what would make it better. Collect any architectural drawings you have. Be ready to discuss your preferences for colour and material, and any constraints like structural limitations or budget. The designer will ask detailed questions; honest answers lead to better results.

Can an interior designer work with existing furniture I want to keep?

Yes. If a piece is structurally sound and fits the direction of the interior, it can be retained. A sofa can be reupholstered; a table can be refinished; inherited pieces can be integrated thoughtfully. The designer assesses what you own and decides what serves the new interior and what doesn’t. Keeping meaningful existing items often makes an interior feel more personal and lived-in.

What happens if I want to change something during the design process?

Changes are managed within the relevant stage. If feedback arrives during Concept, the direction can shift. If a change emerges during Concept, Design & Specification, it may affect the timeline or require revised drawings. Changes during Commission are possible but become costly if bespoke items are already in production. The clearer the brief in Discovery, the fewer surprises later. The designer is transparent about the impact of any change.
