# Banks and Financial Services: Branches, Back Offices and Trading Floors

> Bank interior fit-out covers branches, NBFC offices, back offices and trading floors, where security zoning, customer areas and dependable power and IT shape the layout. The bank's own security and branch standards set the requirements; the fit-out contractor's job is to build them consistently, often across many sites from one standard design, without missing the opening date.

## Security, customers and uptime in one floor plan

A bank branch looks like a small office with a counter. It is closer to a security-zoned
building with a public front: customers, staff, cash and records each need their own zone,
and the bank's security department has to accept the result before the branch opens.
Behind the branch sit back offices and, in some firms, dealing rooms, where the cost of an
outage during business hours is direct and immediate.

The commercial risk is time. A branch that fails its security walk-through or waits on a
strongroom door does not open, and in a rollout one late item repeats across every site
that uses the same design.

## Spaces and the services behind them

| --- | --- | --- |
| Banking hall and customer areas | Clear queuing, privacy for discussions, accessibility, brand | [Turnkey office fit-out](/services/interior-fit-out/turnkey-office-fit-out) |
| Wayfinding and branding | Consistent signage and graphics across sites | [Office signage and wayfinding](/services/interior-fit-out/office-signage-and-wayfinding) |

## Security zoning: public, staff and secure

A branch is planned in layers: the public banking hall, staff-only areas, cash handling,
and the strong room and lockers at the most protected point. Doors between layers are
access-controlled, sight lines from staff positions cover the customer area, and CCTV
coverage is drawn with the layout rather than added to it.

The customer side deserves the same care. Queuing space, a step-free entrance and
counters at more than one height make the hall usable for everyone, and a closed or
screened desk lets customers discuss loans and accounts without being overheard. Where a
branch has an ATM lobby open outside banking hours, it needs its own entrance, lighting
and security boundary, so the lobby can stay open while the rest of the branch is
locked.

Strong rooms, strongroom doors and safes are specialist products. Their burglary resistance
is tested and classified under standards such as **EN 1143-1**, and the grade a branch needs
is set by the bank's security specification within its regulatory framework, not by the
contractor. What the fit-out contributes is the room around them: walls, slab, structure
and services coordinated with the specialist supplier, and a structural engineer's check
that the floor can carry safes and locker cabinets where the plan puts them.

## Back offices and trading floors: density and reliability

Operations floors are planned for density, so power and data reach every desk and heat from
screens and people is handled by the air conditioning design. Trading floors go further:
multi-screen desks, heavy cable volumes and circuits backed by UPS and generator. Cabling
follows **ISO/IEC 11801** and wiring practice **IS 732**, with power and data segregated and
spare capacity in the routes. The planning approach for a head office is shown in our
[NBFC head office design study in Delhi](/our-designs/nbfc-head-office-design-netaji-subhash-place-delhi),
a concept that compares three layouts on one floor plate. For the wider workplace
questions, see [corporate office interiors](/industries/corporate-offices).

## Rolling out many branches from one design

Most banks and NBFCs open branches in programmes, not one at a time. That works when there
is a design kit: typical layouts for a few branch sizes, a specification and approved
materials list, brand elements with physical samples, and one snag checklist. Each site is
surveyed and the kit adapted to its landlord, structure and services. Long-lead items are
ordered centrally, and brand consistency is checked against the samples, not memory, so a
customer sees the same branch in every city.

## Common mistakes

- **Choosing the strong room location before the slab is checked.** The room moves late.
- **Adding CCTV after the ceiling.** Cameras end up where the grid allows.
- **Treating the trading floor as a dense office.** Power and cooling run out first.
- **No design kit for a rollout.** Every branch is redesigned and looks different.
- **Ordering strongroom doors per site.** The slowest delivery sets every opening date.
- **ATM lobby inside the branch boundary.** The whole branch must stay unlocked for it.

## What to ask before design starts

- Has the bank's security specification been issued, and who signs off against it?
- Has a structural engineer checked the slab for the strong room and lockers?
- How are power and data backed up for trading and operations floors?
- Which items are procured centrally for a rollout?
- How will brand consistency be checked at each handover?

## Standards referenced

Fire and life safety for business occupancy under **NBC 2016, Part 4**; burglary resistance
of safes and strongrooms classified under **EN 1143-1**; structured cabling to
**ISO/IEC 11801**; electrical wiring to **IS 732**. Security requirements are set by the bank
or financial institution within its regulatory framework. Structural capacity, fire
protection and services design for a particular site are established by the project's
consultants and the authority having jurisdiction.

## Frequently asked questions

### Who decides the security requirements for a bank branch?

The bank. Its security department sets the specification for strong rooms, lockers, cash areas, alarms and CCTV, within the regulatory framework that applies to it. The fit-out contractor builds to that specification and coordinates the specialist suppliers; it should not be choosing security levels on the bank's behalf.

### Can a strong room be built on an upper floor?

That depends on the building. Strong rooms, safes and locker cabinets are heavy and concentrate load on the slab, so a structural engineer has to assess the floor against the actual layout before the location is fixed. Many branches settle this at site selection rather than at design.

### How is a standard branch design rolled out across many sites?

Through a design kit: typical layouts for a few branch sizes, a specification and approved materials list, brand elements, and a standard snag checklist. Each site is surveyed and the kit adapted to it. Long-lead items such as strongroom doors, locker units and signage are usually procured centrally so every site is not waiting on its own order.

### What makes a trading floor different from an ordinary office?

Density and uptime. Multi-screen desks draw more power and give off more heat than standard workstations, cabling volumes are high, and a power or network interruption during market hours has a direct cost. Power, cooling, cable routes and backup are designed first and the furniture layout follows them.

### Is a branch fit-out different in an NBFC office?

Often the security scope is lighter, because many NBFC offices do not handle cash in the same way as a bank branch, but customer areas, privacy for discussions, document storage and IT reliability remain central. The client's own operating and security policies define the scope.
