A growing team hits the same wall twice: the office that felt roomy last year is full, and the search for a bigger one starts from scratch. This page is the shortcut. Three sizes, what each one holds, and the exact spaces at The Smith that fit.
If you are looking for larger office space in Kingston upon Thames, the question underneath is usually simple: how many square feet does a team of this size actually need, and what is available near me at that size? This is a plain guide to three of the most common sizes, office space for 10 people, office space for 20 people, and a whole floor to rent, set out with real square footage and what each one fits. The Smith is a Grade A building on London Road in central Kingston, and it runs from single desks up to whole floors, so the same building can take a team as it grows. Below is how the sizes work, and where each one sits here.
| Team size | Comfortable area | What it fits | At The Smith |
|---|---|---|---|
| 10 people | 800 to 1,000 sq ft | 10 desks, a small meeting room, a kitchen point | Fitted first-floor suites, move-in ready |
| 20 people | 1,600 to 2,000 sq ft | 20 desks, meeting rooms, breakout and storage | A part floor or a pair of combined suites |
| A whole floor | 4,000 sq ft and up | Your own reception feel, kitchen, branding, 24/7 access | Second floor about 4,078 sq ft, rear first floor about 8,450 sq ft |
01How to size a larger office
Before the sizes, one rule of thumb that saves a lot of second guessing. Allow about 80 to 100 square feet per person for a comfortable fitted office. Run a little denser and you fit more people in the same room, allow a little more and you gain your own meeting rooms, storage and breakout space rather than sharing the building's. The other rule matters just as much: size for where the team will be in a year, not only for today, because the cost of a move usually dwarfs the cost of the extra desks. With those two in mind, the three sizes below fall into place.
02Office space for 10 people in Kingston upon Thames
A team of 10 is comfortable in roughly 800 to 1,000 square feet. That holds 10 desks with room to spread out, a small meeting room of your own, and a kitchen point, without feeling packed. Go towards the top of that range, or a little above, if you want a proper meeting room and a breakout corner rather than hot-seating the one table.
At The Smith, office space for 10 people in Kingston upon Thames means a fitted suite on the first floor. The suites here sit in the 800 to roughly 1,160 square foot band, come furnished if you want them that way, and are ready to move into rather than fit out from a bare shell, so a team can be working within days rather than months. You can see all office suites to let in Kingston and the current sizes there.

03Office space for 20 people in Kingston upon Thames
Double the team and the maths holds: 20 people want about 1,600 to 2,000 square feet, and closer to 2,400 if you want two or three meeting rooms, a decent breakout space and room to keep adding desks through the year. At this size the shape of the space starts to matter as much as the area, because 20 people need somewhere to take a call and somewhere to gather that is not the main floor.
For office space for 20 people in Kingston upon Thames, The Smith offers a part floor or a pair of combined suites, and the rear building divides down to about 3,450 square feet, which comfortably suits a team of 20 to 35 with clear room to grow into. Take a little more than you need today and you avoid the second move when you hire. The complete guide to office space in Kingston sets out the four types of space if you are still weighing serviced against self-contained.

04A whole floor office to rent in Kingston upon Thames
Beyond about 30 people, or when you want the building to feel like yours, the answer is a whole floor. A floor gives you a single, self-contained space you can lay out as you like, with your own reception point, kitchen and branding, secure 24/7 access, and no shared corridors between your teams. It is the option that reads as a headquarters rather than a suite.
A whole floor office to rent in Kingston upon Thames is available here in two forms. The second floor is about 4,078 square feet and can be split if you do not need all of it at once. The rear building first floor is about 8,450 square feet, available as a single whole floor or divided into roughly 3,450 and 5,000 square feet. For a sense of the company a floor here keeps, the building's larger occupiers include Wolters Kluwer at around 8,500 square feet and TMA Data Management at around 7,600, so a full floor is a proven size in this building, not a stretch. Read the full building specification for what comes as standard on every floor.
05What every size includes
Whichever size you take, the building underneath it is the same, and it is the part that is easy to underrate on a floor plan. The Smith was rebuilt from the shell up and completed in April 2021, with the aim of matching the standard of a central London office at a Kingston address, and it has been occupied by established businesses ever since. Every size comes with full fibre broadband, air-conditioning and LED lighting, a staffed reception during business hours, secure 24/7 access and several lifts, bookable meeting rooms, and a business lounge and breakout space beyond your own four walls.
There is also the practical part that decides how a working day actually feels. More than 100 on-site parking spaces with EV charging, so staff and visitors park at the building. Two mainline stations, Kingston and Norbiton, each about a ten minute walk, reaching London Waterloo by direct South Western Railway service in around half an hour, with the A3 close by for anyone driving. Kingston itself, run by the Royal Borough of Kingston, puts shops, riverside and places to take a client a short walk from the door. You can see all of it on the location page.
06Room to grow, without moving again
The quiet advantage of taking larger office space in a building with range is that your next move can happen inside the same walls. Start in a fitted suite for 10, take a larger suite or a part floor as you reach 20, and step up to a whole floor when you outgrow that, all without a full relocation, a new commute for the team, or a fresh search. For growing teams that is often worth more than any single line on the specification, because it turns the usual three-year scramble into a short conversation with the people who run the building.
Common questions
A fitted office of roughly 800 to 1,000 square feet suits a team of 10 comfortably, with room for desks, a small meeting room and a kitchen point. The Smith, on London Road in central Kingston, has fitted suites on the first floor in this range, furniture optional, that a team can move into quickly rather than fitting out from a shell.
A team of 20 is comfortable in about 1,600 to 2,000 square feet, more if you want your own meeting rooms and breakout space. At The Smith that means a part floor or a pair of combined suites, and the rear building splits down to about 3,450 square feet, which suits a growing team of 20 to 35 with room to add desks.
Yes. The Smith has whole floors available, a second floor of about 4,078 square feet that can be split, and a rear building first floor of about 8,450 square feet, available as a whole floor or divided into roughly 3,450 and 5,000 square feet. A whole floor gives you your own reception feel, kitchen, branding and 24/7 access.
As a rule of thumb, allow about 80 to 100 square feet per person for a comfortable fitted office. Run a little denser and you can fit more in, allow a little more and you gain your own meeting rooms, storage and breakout space. It is worth sizing for where the team will be in a year, not only today.
Yes, and it is the main reason growing teams choose a building with range. At The Smith you can start in a fitted suite and move up to a larger suite, a part floor or a whole floor in the same building, without a full relocation, so growth does not mean starting the search again.

07Conclusion: choosing larger office space in Kingston upon Thames
Larger office space in Kingston upon Thames comes down to matching the team to the square footage, then giving yourself a little headroom for the year ahead. A team of 10 wants around 800 to 1,000 square feet, a team of 20 around 1,600 to 2,000, and a whole floor starts at about 4,000 and runs to the 8,450 square foot floor in the rear building. The Smith has all three, in one Grade A building with parking at the door, so the office that fits today does not become next year's problem.
The surest way to size it is to stand in the space. So, roughly how many people will you be a year from now, and would you rather see the suite, the part floor and the whole floor in person before you decide? If so, tell us the size you have in mind and we will show you what fits.
