The Design Office & Correspondence
Running the practice — and the codes the work must meet
A design practice is a professional instrument: it lets good design be delivered reliably. This unit covers the types of office and their staff structure; the discipline of records, accounts and minutes; the coordination of many consultants on a large project; and the codes of fire, light, air, power and barrier-free access the finished work must meet.
Learning objectives
By the end of this lesson, you will be able to — mapped to the course outcomes for Professional Practice:
Describe the types of interior design office and their staff structure.
Explain the filing of records and drawings, the maintenance of accounts, and the recording of minutes of meetings.
Explain the coordination of consultants on a large project, and the codes the work must meet.
The office & its discipline
A practice can be a proprietorship, partnership, LLP or company — differing in liability — with a staff structure that makes clear who is responsible and who signs off. It runs on records: version-controlled drawings, kept correspondence, proper accounts, and dated minutes, because an undocumented decision is a future argument.[3, 4]
How a practice is organised
An interior design practice can be set up in several LEGAL FORMS — a sole PROPRIETORSHIP (simplest, but the owner is personally liable), a PARTNERSHIP, a LIMITED LIABILITY PARTNERSHIP (LLP, which limits partners' liability), or a private limited COMPANY (a separate legal person) — each with different liability, tax and compliance. Inside, a STAFF STRUCTURE grows with the work: a principal designer, project/senior designers, junior designers and draughtspersons, and support for accounts and administration; on larger practices, roles specialise. The point is not the org chart but CLARITY — who is responsible for what, who signs off, who talks to the client. A well-run office is a professional instrument: it lets good design be delivered reliably, on time and on budget, rather than depending on one person's memory.[3, 4]
Coordination & the codes
On a large project the designer coordinates many consultants into one clash-free design, catching clashes on paper. And the work must meet the codes — fire safety, lighting, ventilation, electrical (MCB + RCCB) and barrier-free access — cited to their current status: SP 7:2026 (which superseded NBC 2016 / SP 7:2016) and the Harmonised Guidelines 2021.[3, 1]
Many specialists, one design
On a LARGE project the interior designer works with many CONSULTANTS — structural, MEP / services, HVAC, electrical, plumbing, lighting, acoustic, fire and sometimes IT / security — and the designer's job is to COORDINATE them into one resolved design. That means holding the whole picture, running coordination meetings, exchanging and reconciling drawings, catching CLASHES on paper before they appear on site (a duct through a beam, a light where a sprinkler must go), and keeping statutory and structural work with those licensed for it. The section and the reflected ceiling plan are where the coordination is proven. On a big job this coordination is a large part of the professional's real value: the specialists each know their own trade deeply, but only the coordinating designer keeps the design whole. Poor coordination is the commonest cause of delay, rework and blame on a complex project.[3, 4]
At a glance
| Aspect | The fact | The folklore |
|---|---|---|
| An LLP or company | Limits the partners'/owners' personal liability | The same as a sole proprietorship |
| Minutes of a meeting | A dated record of decisions and actions — an undocumented decision is a future argument | Optional paperwork |
| Coordination on a big project | The designer holds the whole picture and catches clashes on paper | Each consultant just does their bit |
| India's model building code | SP 7:2026 (superseded NBC 2016 / SP 7:2016, now WITHDRAWN) | NBC 2016 is still the current code |
| Barrier-free access | Governed by the Harmonised Guidelines 2021 under the RPwD Act 2016 | Optional / only for public buildings |
Key terms
Sole proprietorship, partnership, LLP or private limited company — differing in liability, tax and compliance; LLP and company limit personal liability.
Keeping drawings, documents and correspondence organised and current so the right revision is always used — the wrong revision on site is a real hazard.
A dated record of who attended, what was decided and who does what by when — circulated so everyone works from the same agreed version of events.
Resolving many specialists' inputs into one clash-free design on a large project — a large part of the professional's real value.
India's model National Building Construction Standards 2026, which superseded the National Building Code 2016 (SP 7:2016, now withdrawn).
India's standards for universal accessibility, under the Rights of Persons with Disabilities Act 2016 — ramps, clear widths, accessible toilets, step-free access.
Study task
Sketch the set-up of a small practice you might one day run: choose a form (proprietorship, partnership, LLP or company) and say why; draw a simple staff structure for five people and note who signs off drawings and who talks to the client; and list the records you would keep and how you would version-control drawings. Then write a short set of minutes for an imagined client meeting — attendees, three decisions, and who does what by when. Finally, list the codes (fire, light, air, electrical, barrier-free) your work must meet and note who certifies them. The goal is to run a practice as a professional instrument, not from memory.
Self-assessment
1. Why does a practice keep minutes of meetings and full correspondence?
2. What is the interior designer's job in coordinating consultants on a big project?
3. What is India's current model building code status?
4. Which form of practice limits the owners' personal liability?
