What Should You Finalise Before Starting Interiors in a New Flat?
Before interior work begins, finalise your room requirements, verified measurements, furniture layout, storage needs, appliance specifications, service requirements, materials and itemised budget. Agree on responsibilities, approvals and the work sequence with your execution team.
You do not need to choose every cushion before starting. Focus first on decisions that affect construction, fabrication and installation.
For example, your bed position influences bedside switches. Your refrigerator model affects its cabinet opening. Your wardrobe layout determines whether you can comfortably open its shutters.
This checklist helps you make those connected decisions before they become expensive changes.
1. Inspect the flat and record its existing condition
Walk through the apartment before interior work starts. Photograph each room and record visible issues that need clarification or attention.
Look for damaged finishes, signs of dampness, problems with doors or windows and discrepancies between the floor plan and the completed space. Arrange appropriate professional checks where needed.
Record which issues belong to the builder's handover process and which fall within your interior project.
Give your execution team a clear list of existing finishes and fittings that must be protected.
2. Verify measurements before designing fixed furniture
Use the builder's plan as a starting reference, then check the actual site.
Your design and execution teams need to account for:
- Wall lengths and ceiling heights.
- Beams, columns and changes in wall depth.
- Door positions, widths and opening directions.
- Window sizes, sill heights and shutter movement.
- Existing electrical, plumbing and other service locations.
- Skirting, ledges and fixed projections.
- Access for bringing furniture and materials into the home.
Identify who is responsible for the final measurement check before fabrication. Do not assume everyone is working from the same dimensions.
3. Write a practical brief for every room
Describe what the room needs to support on an ordinary day.
| Room | Questions to answer |
|---|---|
| Living room | How many people sit here daily? Do you need a TV, play area or workspace? |
| Dining area | How many seats are needed? Where will crockery and serving items go? |
| Kitchen | Who cooks, how often and with which appliances and utensils? |
| Main bedroom | What bed, clothing storage, dressing and charging arrangements are required? |
| Second bedroom | Is it primarily for children, guests, work or a combination? |
| Foyer | Do you need shoe storage, seating, keys or bag storage? |
| Utility | Where will laundry, cleaning supplies and drying activities fit? |
| Puja area | What needs to be displayed, stored and accessed during daily use? |
List existing furniture and appliances you intend to keep. Add their dimensions to the brief.
4. Finalise the furniture layout before buying
Review the major furniture pieces together, rather than choosing them one at a time.
Check the bed, wardrobe and dressing area as a complete bedroom arrangement. In the living room, consider seating, the TV, tables and walking routes together.
Ask the designer to show how the layout accommodates:
- Doors and drawers opening.
- Dining chairs being pulled out.
- Movement between rooms.
- Access to windows and curtains.
- Cleaning around furniture.
- Everyday use by the people living there.
Where useful, mark furniture footprints on the floor with removable tape to understand their scale.
Approve positions and dimensions before ordering furniture that is difficult to return or alter.
5. Plan storage around what you own
Start with an inventory.
For wardrobes, list hanging clothes, folded garments, drawers, luggage, linen and seasonal items. For kitchens, include large cookware, grocery containers, small appliances and cleaning supplies.
Then decide where those items should live and how often you need to reach them.
Check internal dimensions as well as the unit's overall size. A cabinet may fit the room while its shelves or drawers fail to accommodate the intended contents.
Ask for internal arrangements to be recorded before fabrication.
6. Select appliances before dependent cabinets are made
Appliance choices can affect cabinetry, countertops and services.
| Appliance | Information to confirm |
|---|---|
| Refrigerator | Overall size, door movement and manufacturer-required clearances |
| Hob | Model, cut-out requirements and installation instructions |
| Chimney | Model, mounting requirements and proposed duct route |
| Built-in oven or microwave | Cabinet opening, ventilation and connection requirements |
| Dishwasher | Dimensions, door movement, water supply, drainage and power requirements |
| Washing machine | Dimensions, loading access and service requirements |
| Air conditioner | Unit positions, routing, drainage and maintenance access |
Have the relevant installer or professional check these requirements against the selected products.
If a model is undecided, identify which fabrication decisions must wait. Avoid treating an assumed appliance size as final.
7. Coordinate electrical points with the layout
Review electrical requirements after the main furniture and appliance positions are clear.
Consider bedside charging, reading lights, the TV, work desks, kitchen appliances, the router and cleaning equipment.
Ask the electrical professional to confirm the necessary circuits, protection and installation details. The interior plan should communicate your intended use and positions clearly.
Before the affected work begins, check that switches and sockets will remain accessible after wardrobes, beds, panelling and appliances are installed.
Record the approved locations in a coordinated drawing or marked plan.
8. Decide the ceiling and lighting together
A ceiling design affects available height, lighting positions and access to services.
Before approving it, coordinate the proposed ceiling with beams, fans, air-conditioning arrangements, curtain tracks and any services above it.
Discuss how the room will be used at different times. General lighting, reading light and kitchen task lighting serve different purposes.
Ask the designer and execution team to confirm fixture positions, switching arrangements and required access before ceiling work starts.
Choose decorative fixtures early if their dimensions or installation requirements affect the work.
9. Approve materials using physical samples where possible
A render helps you understand the overall design, but material selection needs more detail.
Review samples of laminates, paint, fabrics, stone and other important finishes together. Look at them under the lighting conditions available in your home where practical.
Record the selections clearly:
- Manufacturer or brand.
- Product name and code.
- Colour and finish.
- Intended location.
- Agreed specification.
- Approved alternative, if any.
Ask for approval before a selected product is substituted. Keep a dated selection sheet so the designer, vendor and installer can refer to the same information.
10. Build one complete interior budget
Bring all expected expenses into one budget, even when different vendors supply them.
Separate fixed furniture, loose furniture, appliances, site work, lighting, furnishings, design fees and applicable taxes or delivery charges.
Mark each amount as an estimate, quotation or approved order. Keep excluded but necessary purchases visible.
Also identify items you can postpone without disrupting completed work.
Before accepting a quotation, confirm its quantities, specifications and exclusions. Compare vendors against the same requirements so a lower total does not simply represent less work.
11. Agree on approvals, responsibilities and sequencing
Ask your execution team to prepare a project-specific work sequence.
Some decisions need to be settled before others can proceed. Appliance requirements affect cabinets; service work can affect walls and ceilings; finished surfaces need protection during later installations.
For each stage, establish:
- Who carries out the work.
- What must be approved first.
- Who checks completion.
- What information the next team needs.
- How changes are recorded.
- Which decisions remain outstanding.
Check the building's rules for working hours, deliveries, lift use and waste removal. Share them with the team before work is scheduled.
What must be decided now, and what can wait?
| Decision | When to resolve it |
|---|---|
| Major furniture positions | Before coordinating services and fixed furniture |
| Appliance models or verified requirements | Before dependent cabinetry and installation details are finalised |
| Cabinet dimensions and interiors | Before fabrication |
| Electrical and plumbing requirements | Before the affected site work |
| Ceiling and lighting coordination | Before ceiling installation |
| Fixed finishes and hardware | Before procurement or fabrication |
| Curtain arrangement | Early if tracks, pockets or pelmets affect other work |
| Rugs, artwork and small décor | Often later, after key dimensions and finishes are settled |
Treat this as a planning guide. Your execution team should confirm the sequence for your particular flat.
Frequently asked questions
Should I start interior planning before possession? You can develop a brief, budget and preliminary layout before possession. Verify actual site conditions and dimensions before releasing work that depends on them.
What should I buy first? Start with the plan rather than a shopping list. Select products whose dimensions affect the design early, but coordinate purchase and delivery with the project schedule.
Do I need to complete every room at once? No. You can phase the work. Identify any shared services or dependencies that should be addressed together to avoid disturbing finished rooms later.
Should I keep the builder-provided flooring? Assess its condition, appearance and suitability for your plan. Discuss protection during work and any implications for levels or adjoining finishes before deciding.
Is a 3D render enough to start execution? Not by itself for every type of work. Your team may also need verified dimensions, drawings, specifications and service details. Confirm what is required before fabrication or installation.
When should I confirm my move-in date? Review the actual work programme, installation status and remaining checks with your execution team. Allow for the completion of essential services, cleaning and unresolved items before planning occupation.
