Workplace Interior Design Company: Briefing With Real Data

Most office projects start with a conversation: how many people, how many rooms, what style. Each answer is a guess, and each guess becomes square feet, joinery and rent for the next five years.

This guide is for owners, HR and admin managers in Malaysia who are about to brief a workplace interior design company. It covers what data to collect, how much of it is enough, how to turn it into a desk count, and what the law says about tracking staff.

CTN Interior Solutions has designed and built offices in Malaysia since 2001. Every figure below comes from a public source or is clearly marked as modelled.

The US General Services Administration session below shows how a large office owner measures daily use before it plans space. The same methods scale down to a 30-person office in Petaling Jaya.

1. What Does a Workplace Interior Design Company Need From You?

Quick Answer: Your designer needs facts it cannot see on a site visit: how many people will use the office, on which days, for what kind of work, and under which landlord rules. Opinions about style come later. Without these facts, the designer has to guess, and guesses usually mean too much space.

Designers are good at turning needs into layouts. They are poor at guessing needs, because nobody outside your company knows how your teams actually work. When a brief says “80 staff, 6 meeting rooms, modern look”, the designer will draw exactly that, even if 30 of those staff are rarely in.

Research for large firms shows the same gap. In JLL’s 2025 Occupancy Planning Benchmark, only 7% of organisations rated their own data collection as excellent. If large corporate real-estate teams struggle with this, most growing Malaysian firms are unlikely to have clean data either.

The good news is that most of what a designer needs can be collected in four weeks, at little cost:

• People facts: headcount now and planned, and how many come in each day.
• Work facts: meeting sizes, focus work, calls and visitors.
• Building facts: the landlord’s fit-out rules, services and floor plate.

This data is what separates a workplace design and build project that fits from one that is redone in three years.

2. Which Data Should You Bring to the First Briefing?

Quick Answer: Bring seven sets of facts: a headcount plan, four weeks of daily attendance, meeting-room bookings, walk-through counts, a short staff survey, the building’s fit-out rules and basic comfort readings. Each one answers a different design question, from desk count to air-conditioning scope.

You do not need software for most of this. Many office door-access systems already log entries, and calendar tools can export room bookings. A clipboard walk at 10am, 2pm and 4pm for two weeks gives a surprisingly clear picture.

If you have not yet written the brief itself, our guide on how to write an office design brief shows where each data set fits.

3. How Busy Are Offices Really? Utilisation vs Occupancy

Quick Answer: Global offices now run about half full on an average day. CBRE measured average utilisation at 53% in 2025, up from 35% in 2023, while peak days reached 80%. Occupancy, meaning people assigned per seat, rose to 111%. Your own numbers matter more, because Malaysian attendance runs higher.

Two words get mixed up in almost every briefing:

• Occupancy is how many people are assigned to the building per seat. CBRE’s figure of 111% means more people are allocated than there are seats.
• Utilisation is how many seats are actually in use at a given time. That is the number that decides your desk count.

JLL’s benchmark tells a similar story: 54% utilisation in 2025, up from 49%, against a target of 79%. But do not copy global averages into a Malaysian brief. A Monash University Malaysia survey reported by Malaysiakini found 80.5% of white-collar staff work fully on-site. Many local offices are far busier than the global figures suggest.

4. How Many Staff Should You Survey Before a Redesign?

Quick Answer: In a small office, you need most staff to answer before the results mean much. For 50 people, 45 responses give a 5% margin of error; for 500 people, 218 are enough. Aim for at least half of all staff, and keep the survey under ten questions so people finish it.

The table shows why a survey of 10 people in a 100-person firm proves very little. Small offices need near-full participation, so keep the form short and ask managers to give time for it.

Good questions ask about behaviour rather than wishes:

• Ask: “Where did you take your last private call?” rather than “Do you want phone booths?”
• Ask: “How many days did you come in last week?” rather than “How many days would you like to come in?”
• Ask: “What stopped you working well yesterday?” to find the real problems.

Our guide to office design solutions for common workplace problems lists simple checks for noise, air and crowding that pair well with the survey.

5. Should You Size the Office for Average or Peak Days?

Quick Answer: Size for your busiest normal day, plus a small buffer. Sizing to the average day leaves people without desks when everyone is in; sizing to full headcount pays for empty desks. For a 100-person team in Kuala Lumpur, the gap between the two is about RM291,000 a year in rent.

The model makes one point clear: the average day is the wrong number to plan with. It looks cheapest, but on a Tuesday all-hands, 27 people have nowhere to sit, and they will book meeting rooms as desks.

Three rules keep the sizing honest:

1. Use your own peak. Take the busiest normal day in your four-week count, not a one-off event.
2. Add growth. Apply the headcount plan for the lease term, not just today’s team.
3. Agree the rules first. Desk sharing only works if team days and booking rules are agreed before the layout is drawn.

Our guide to office interior solutions for hybrid work explains how to set those team days.

6. Is Workplace Data Covered by Malaysia’s PDPA?

Quick Answer: Often, yes. Door-access logs, Wi-Fi records and booking data linked to names are personal data under Malaysia’s Personal Data Protection Act. Since 1 June 2025, many organisations must appoint a data protection officer and report data breaches. Share only counts or anonymised data with your designer.

The Personal Data Protection (Amendment) Act 2024, summarised by LAW Partnership came into force in three stages in 2025. The final stage, on 1 June 2025, brought data protection officer duties, mandatory breach notification and a right to data portability.

For a design brief, the safe approach is simple:

• Count, do not track. A designer needs “62 people on Tuesday”, not who those people were.
• Tell staff first. Explain what you are counting, why, and for how long.
• Strip names before sharing. Export totals by day and by team, then send only those.
• Set an end date. Delete raw logs once the study ends, unless you have another lawful reason to keep them.

This is general information, not legal advice. Your data protection officer or legal adviser should confirm what applies to your company.

7. How Does a Workplace Interior Design Company Turn Data Into a Layout?

Quick Answer: A good design firm turns each data set into a decision: attendance into desk count, bookings into room sizes, walk-throughs into the mix of focus and team space, and building rules into what can move. Ask any firm you shortlist to show this link between your data and their drawings.

How a firm handles your data also tells you a lot about the firm. Watch for these signs at the first meeting:

• Good sign: the firm asks for attendance and booking data before it shows a mood board.
• Good sign: it explains its desk count in writing, with the assumptions shown.
• Warning sign: a full layout arrives before anyone has asked how your teams work.

A space planner who only arranges furniture is closer to a decorator; see office interior decorator vs designer for where that line sits. Our complete guide to office interior design in Malaysia shows where the data fits in a full project, and what an office floor plan designer should deliver covers the drawings.

8. How Do You Build a Briefing Data Pack, Step by Step?

Quick Answer: Name one owner, collect the headcount plan, run a four-week attendance count, export room bookings, survey staff and gather the landlord’s rules. Anonymise everything and send it as one pack before the first design meeting. Most offices finish this in about a month without extra software.

1. Name an owner: Pick one person, usually from HR or admin, to run the data pack and be the designer’s single contact.
2. Get the headcount plan: Ask finance and team heads for numbers now and over the lease term, by team.
3. Start the four-week count: Export daily door-access or Wi-Fi totals, or count people at 11am and 3pm each day.
4. Export room bookings: Pull at least four weeks of bookings with the number of attendees and the room size.
5. Run a short survey: Ask under ten behaviour-based questions and aim for at least half of staff to answer.
6. Collect the building rules: Get the landlord’s fit-out guide and the as-built drawings, then send the whole pack, anonymised, to the designer.

If you are still choosing between buildings, run the count before you sign and use it in a test-fit before you lease. Then check any firm against our 15 questions for an office interior designer.

9. Conclusion: Bring Facts, Get a Better Office

Quick Answer: The best briefing you can give a workplace interior design company is a short, honest data pack. Count attendance, check bookings, survey staff, collect building rules and size for your real peak day. The design that follows will fit your people and your rent.

Style still matters. It just comes after the numbers, not before them. When every firm you invite works from the same data, their proposals also become much easier to compare.

10. Frequently Asked Questions

1. What does a workplace interior design company do?

It plans and designs office interiors around how people work, covering layout, furniture, finishes, lighting, air and services. Many also build the design under one contract.

2. What data should I give an office designer?

A headcount plan, four weeks of daily attendance, meeting-room bookings, a short staff survey, the landlord’s fit-out rules and basic comfort readings.

3. What is the difference between occupancy and utilisation?

Occupancy is how many people are assigned per seat. Utilisation is how many seats are actually in use at a given time, and it is the number that sets your desk count.

4. How long should an office attendance study run?

Four weeks is a practical minimum. It covers each weekday several times and catches month-end or team-day peaks.

5. Can I share door-access data with a designer?

Share daily totals or anonymised counts only. Name-linked logs are personal data under Malaysia’s PDPA, so check with your data protection officer first.
