Planning a beautiful home is exciting, but one practical question usually comes first: how much will the complete interior design cost?
There is no single price that suits every home. Two properties with the same number of bedrooms may require very different budgets because their kitchens, storage needs, materials, furniture, lighting and level of customisation are different.
This guide gives Kerala homeowners a realistic starting point for planning 1, 2, 3 and 4 BHK interiors. A site measurement, approved design brief and itemised quotation are still necessary for a dependable project price.
01 / PROJECT SCOPEWhat can a home interior quotation include?
A complete residential interior proposal may cover design, customised furniture, material supply, installation and supervision. Always compare inclusions—not only the final total.
- Space planning and layouts
- Concept and 3D visualisation
- Modular kitchen
- Wardrobes and bedroom units
- TV and living-room furniture
- Dining and crockery storage
- False ceiling coordination
- Electrical modifications
- Wall finishes and panelling
- Custom furniture
- Material procurement
- Site supervision
Appliances, loose furniture, curtains, decorative lights, civil alterations and specialised accessories may be priced separately. Ask for a written room-wise scope before approval.

03 / KEY VARIABLESWhat affects house interior design cost?
Scope of work
A kitchen-and-wardrobe project costs less than a complete turnkey interior covering ceilings, electrical changes, wall finishes and every room.
Property size and layout
Floor area is only one part of the calculation. Compact apartments with storage on every wall may cost more per square foot than larger homes with fewer built-ins. Columns, uneven walls and narrow access can add custom work.
Materials and finishes
Plywood grade, board type, laminate, acrylic, veneer, glass, stone and surface finish influence durability, maintenance and price. Kerala’s humidity makes moisture suitability particularly important.
Customisation
Curved furniture, special dimensions, concealed features and complex detailing require more design and production time. Customise where it improves storage, movement or comfort—not merely for decoration.
Hardware and accessories
Hinges, drawer channels, lift-up systems, internal baskets and organisers can significantly affect kitchen and wardrobe costs. Invest most in components that receive frequent use.
Site condition and location
Dismantling, wall repairs, moisture treatment, electrical relocation, plumbing changes, access restrictions and transportation can affect both the estimate and timeline. A site inspection is essential.
04 / EARLY ESTIMATIONInterior design cost per square foot
A square-foot rate is useful for early planning but should never replace a room-wise quotation. A smaller home with extensive cabinetry can have a higher rate than a larger home with fewer units.
| Interior level | Approximate rate | Typical scope |
|---|---|---|
| Essential | ₹1,000–₹1,500 / sq. ft. | Functional interiors, basic finishes and limited customisation |
| Standard | ₹1,500–₹2,500 / sq. ft. | Complete interiors, dependable materials and customised storage |
| Premium | ₹2,500–₹4,000+ / sq. ft. | High-end finishes, detailed furniture and premium specifications |
Confirm whether a quoted rate covers only furniture or also ceilings, painting, electrical, civil work, installation and supervision.
05 / ROOM-WISE PLANNINGApproximate interior cost by room
| Area | Indicative range | Main cost drivers |
|---|---|---|
| Living room | ₹1.5–₹6 lakh+ | TV unit, storage, wall finish, ceiling and lighting |
| Modular kitchen | ₹1.5–₹8 lakh+ | Layout, cabinet area, countertop, finish, hardware and accessories |
| One bedroom | ₹1.5–₹5 lakh+ | Wardrobe, bed, dressing, study, panelling and lighting |
| Wardrobe | ₹60,000–₹1.2 lakh+ | Size, shutter type, internal layout, finish and hardware |
| Bathroom | ₹40,000–₹4 lakh+ | Vanity-only scope versus complete renovation |
| Dining area | ₹75,000–₹2 lakh+ | Dining furniture, crockery unit, ceiling and wall treatment |
| Foyer | ₹50,000–₹2 lakh+ | Shoe storage, seat, mirror, partition and lighting |
| Home office | ₹50,000–₹3 lakh+ | Desk, shelves, storage, cable management and lighting |
These broad ranges should be used only for initial budgeting. Measurements and specifications determine the actual cost.
06 / BUDGET LEVELSEssential, standard and premium interiors
Essential
Focuses on everyday functionality: a practical modular kitchen, standard wardrobes, a simple TV unit, essential entrance storage, basic laminates and limited ceiling work.
Standard customised
Balances appearance, storage and durability with a custom kitchen, full-height wardrobes, living and dining units, selected false ceilings, improved hardware and coordinated finishes.
Premium
Uses personalised furniture, premium finishes, detailed lighting, full-height panelling, sophisticated accessories and optional smart-home features. Small upgrades across many rooms can significantly raise the total.
Reduce cost without reducing quality
- Prioritise kitchens and wardrobes
- Use simple furniture forms
- Limit premium finishes to highlights
- Avoid unnecessary false ceilings
- Choose durable laminates
- Use premium hardware selectively
- Plan multipurpose furniture
- Complete non-essential work in phases
- Finalise materials before production
- Keep 5%–10% contingency
07 / TRANSPARENCYHow to compare interior quotations
Do not choose a proposal based only on the lowest total. Compare the scope, quantities, materials, installation and service behind each price.
Confirm every furniture unit, service and exclusion.
Look for dimensions, board grades, surface finishes and brand details.
Check hinge, channel, basket and internal-organiser specifications.
Ask whether transport, installation, taxes and site supervision are included.
Review payment stages, timeline, warranty and the method for approving additional work.
Accurate space planning can also save money by avoiding unnecessary cabinetry and reducing changes during execution. Finalising furniture dimensions, appliance positions and electrical points early helps prevent rework.
When should you request an estimate?
Contact an interior design company when you have an accurate floor plan or when the property is available for measurement. Share the area, room count, possession date, preferred style, room-wise requirements, material expectations, budget range and desired timeline.

Frequently asked questions
How much does a 2 BHK interior cost in Kerala?
An essential 2 BHK scope may begin around ₹5–₹8 lakh. A more complete customised interior may range from ₹8–₹14 lakh, while premium specifications can exceed this range.
Is cost per square foot an accurate pricing method?
It is useful for initial planning but not for a final quotation. Furniture quantity, materials, hardware and room-wise scope can change the rate substantially.
What should I prioritise on a limited budget?
Start with the modular kitchen, wardrobes and essential storage. Decorative panelling, elaborate ceilings and loose furniture can be introduced later.
Why can two quotations differ so much?
They may use different material grades, measurements, hardware, finishes or inclusions. One proposal may also exclude transport, electrical work or installation.
Does Scale Art Interiors provide turnkey home interiors?
Yes. The team can coordinate design, 3D visualisation, materials, custom furniture, installation, finishing and handover according to the approved project scope.
