There is no universal “full-service interior design” package. Two proposals using that description may allocate drawings, procurement and site responsibility very differently.
Use this service list to decide what the owner needs, what the designer provides and what another consultant or contractor must cover.
Define early advice with the consultation.
If material selection is included, require a controlled interior material list rather than accepting an unlabelled mood board as the final specification.
What an interior designer actually does
An interior designer translates user needs and site conditions into coordinated decisions about space, function, materials, fixtures, furniture and experience. The work is not limited to choosing colours or producing images. It can include research, measurement, option testing, information coordination, documentation, supplier and contractor communication, and review during delivery.
The exact responsibility depends on the appointment. A designer can advise for one stage, provide design-only information, continue through contractor selection, administer procurement or support the work through handover. The phrase “interior designer” therefore identifies capability, while the service schedule identifies what the client is buying.
Interior design service schedule
| Stage | Typical service | Useful deliverable | Limit to define |
|---|---|---|---|
| Project definition | Briefing, information review and site familiarization | Approved brief and information register | Stakeholders, rooms, surveys and investigations |
| Concept | Layouts, visual direction and early selections | Approved concept package | Number of options, presentations and revisions |
| Developed design | Coordinated room, joinery, lighting and finish decisions | Developed drawings and schedules | Level of coordination and unresolved allowances |
| Technical information | Drawings, details, specifications and schedules | Issued information set with revision | Scale, issue purpose and specialist boundaries |
| Cost and appointment | Estimates, BOQ support, tender queries and comparison | Comparable scope and recommendation | Measurement, price checking and certification role |
| Procurement | Sourcing, ordering and delivery administration | Approved order and delivery register | Commercial model, warranty, storage and returns |
| Site support | Meetings, queries, submissions and design review | Site report, response or approved sample | Frequency, authority and response time |
| Handover | Snagging input, records and closeout | Open-item register and final information | Inspections, testing and completion definition |
Do not copy every row into an appointment by default. Select the services the project needs, then identify who handles every omitted responsibility.
Briefing and existing information
Possible services include stakeholder interviews, site familiarization, measured survey, existing-condition drawings, inventory of retained items and preparation of the project brief.
Clarify whether the designer performs or merely relies on a measured survey. Identify who verifies structural, electrical, plumbing, waterproofing or other concealed conditions.
The brief should record users, activities, priorities, budget structure, decision-makers, programme constraints, retained items and success criteria. The existing-information register should distinguish documented facts from assumptions and items requiring investigation. If the designer is not appointed to perform a specialist survey, the schedule should state who supplies it and when it is required.
Space planning and concept design
This stage may include layouts, circulation, zoning, furniture, visual direction, materials and early cost assumptions. For a shop, use the shop planning guide to test the range, customer journey, checkout and stock before accepting a visual layout.
Define the included rooms, options, revisions and presentation format. A render is not a technical drawing or material specification.
Record an approval gate: selected layout, design direction, preliminary material palette and unresolved items. Concept approval does not make every detail or price final.
Developed design
The selected direction is coordinated across dimensions, joinery, lighting, finishes, furniture, equipment and building services. Samples or reference products may be proposed.
Ask which selections are final specifications and which remain allowances or design intent.
Developed design is where separate decisions must begin to work together. A wardrobe affects circulation, electrical points, lighting, air-conditioning and skirting. A kitchen decision affects appliances, power, plumbing, ventilation, worktop interfaces and storage. Ask how the designer coordinates these overlaps and how unresolved inputs are tracked.
Working drawings and specifications
Depending on the project, deliverables may include:
- demolition and setting-out plans;
- floor, wall and ceiling finish drawings;
- electrical, lighting and switching information;
- plumbing and bathroom layouts;
- joinery working drawings and details;
- door, hardware, finish, furniture or fixture schedules;
- written specifications and revisions.
State drawing scale, detail, issue purpose and responsibility for specialist design; compare source-backed Mumbai lighting designers and consultants when lighting needs a separate appointment.
A drawing labelled “for discussion” is not construction information. Require a title, date, revision and issue purpose. Identify whether fabricators or specialists must prepare shop drawings or calculations, and who reviews them for design alignment.
Cost, quotation and tender support
A designer may prepare a preliminary estimate, scope schedule, BOQ or tender package; suggest contractors; answer tender queries; normalize bids; and prepare a recommendation.
These are different services. Confirm whether quantities are measured, who checks bidder assumptions and whether the designer certifies contractor payments.
Use the quotation comparison guide when proposals arrive.
An early estimate, a measured BOQ, a contractor quotation and a final account are different outputs. If the designer prepares or reviews one, define the information basis and intended use. If the service includes tender support, record the number of bidders, query process, comparison format, recommendation scope and treatment of post-tender clarifications.
Procurement
Procurement can include sourcing, supplier comparison, samples, purchase orders, payment administration, inspection, delivery coordination, storage and returns.
Clarify:
- who contracts and pays the supplier;
- whether the designer receives a margin, discount or commission;
- who owns warranties and manages damage;
- which orders require written owner approval;
- how substitutions and price changes are handled.
Procurement may be advisory, agency-based or direct supply by the designer or a related entity. Record the contracting party on every order, the approval evidence, payment route, delivery location, inspection responsibility and remedy for damaged or incorrect goods. Product selection alone does not include purchase administration unless the schedule says so.
Site coordination and review
Project management, supervision and a site visit are not interchangeable. Define visit frequency, purpose, areas, report timing and authority. State who remains responsible for workmanship, safety, sequence, quantities and compliance. A periodic design review does not imply continuous control of the contractor.
Download the interior design site visit report (PDF). It records the visit basis, observations, queries, actions, owners, due dates, photo references, potential changes and closure evidence without treating the report itself as an instruction or certification.
| Report field | Record |
|---|---|
| Visit basis | Date, attendees, areas, purpose and current document revisions |
| Observation | Exact location, visible fact and photograph or reference |
| Design query | Unclear information, affected work and response owner |
| Action | Required outcome, responsible party, due date and closure evidence |
| Potential change | Scope, cost or time issue linked to the formal change record |
| Limitation | Inaccessible, concealed, untested or unavailable information |
Prefer measurable appointment wording: one scheduled visit per week, named review points, response periods and report format. State how additional, cancelled or out-of-city visits are charged. Preserve each issued report and add dated closure evidence rather than silently rewriting the original observation.
Snagging and handover
Services may include a snag list, follow-up inspection, testing coordination, final finish schedules, warranties, manuals and as-built information.
Define the number of inspections and what closes the appointment. A handover photograph does not replace documented outstanding work.
The closeout schedule may also identify operation information, supplier contacts, care instructions, test results, approved samples, final finish references and record drawings. State who compiles each item and whether the designer verifies completeness or only contributes design documents.
Services that are often assumed but may be excluded
Check these items explicitly rather than treating them as part of “full service”:
- structural, electrical, plumbing, air-conditioning, acoustic, fire or other specialist engineering;
- statutory applications, society approvals or building-management submissions;
- intrusive investigation of concealed conditions;
- daily site management, safety control or contractor labour supervision;
- verification of every installed quantity or contractor invoice;
- warehousing, insurance, delivery acceptance, installation or returns;
- unlimited revisions, meetings, renders, samples or site visits;
- photography, styling, relocation or temporary accommodation;
- as-built surveys and record drawings after contractor changes.
An exclusion is manageable when another competent party owns it. It becomes a project gap when everyone assumes someone else is responsible.
Match the service to the delivery route
| Delivery route | Typical owner need |
|---|---|
| Design only | Strong design documentation; owner separately manages procurement and construction |
| Design plus tender support | Common pricing information and help comparing contractors |
| Design plus site review | Continued design interpretation during contractor execution |
| Procurement service | Documented product selection, ordering and delivery responsibility |
| Turnkey or design-and-build | Clear included, optional and excluded responsibilities under one provider |
Use the role guide, process guide and turnkey guide to define the appointment, then apply one schedule across the Juhu shortlist or Mumbai turnkey contractors.
Scope services for three example projects
| Project | Core service emphasis | Possible limited or separate service |
|---|---|---|
| Furnished-home refresh | Brief, retained-item plan, selected finishes, lighting and purchase schedule | Limited technical drawings; owner-managed contractor work |
| Full apartment renovation | Existing information, complete design stages, coordinated drawings, specification, pricing support and site review | Specialist investigations and daily construction management |
| Workplace or commercial fit-out | Stakeholder brief, test fits, services coordination, statutory interfaces, tender information and delivery reviews | Specialist consultants, landlord approvals and project management under separate appointments |
For an occupied, phased or operational workplace, use the office renovation planning guide to add continuity, landlord, access, move and system-test requirements. Issue that same service schedule to each candidate in the Mumbai office-interior directory.
The right schedule follows actual risk, not project labels. A small room with complex custom fabrication can require more technical information than a larger but lightly furnished area. The interior project mistakes guide shows how vague service descriptions become gaps in pricing, site authority and handover.
Turn the list into an appointment schedule
For each required service, add these columns:
- stage and service name;
- deliverable or recorded action;
- rooms, packages or stakeholders included;
- number of options, revisions, meetings or visits;
- client and third-party inputs required;
- approval evidence and due date;
- named responsible party;
- fee basis and additional-service trigger.
Attach the schedule to the proposal and contract. Map package wording into these rows before comparing fees. This exposes differences without forcing every practice to work alike.
Use the interior design contract guide to connect the service schedule to payment, change and termination terms. The interior designer fee guide explains why a rate cannot be evaluated separately from the stages and limits it covers.
Questions to ask about a service proposal
- Which deliverable proves each stage is complete?
- Which information does the designer produce, verify or merely rely on?
- Which rooms, packages, options and revisions are included?
- Who coordinates specialist information and contractor submissions?
- Which meetings, site visits and response periods are allowed?
- Which procurement income, expenses and taxes are separate?
- What event creates an additional service, and who must approve it first?
- What remains with the owner, contractor or another consultant?
Use the questions to ask before hiring with every candidate. Record the answers beside the service schedule.
Send each Mumbai interior designer the same service schedule and project brief.
