ALDERSGATE ST

Towering ceiling voids, a dedicated cinema room, and thoughtfully designed focus areas come together in a space that truly works.
We’ve transformed the lower ground into a highly attractive environment, using our expertise to create a smart, efficient configuration that feels anything but secondary.

THE SPACE

MAIN FLOOR

We were commissioned to deliver a fully bespoke fit-out for tenants specialising in visual effects production. The brief called for intelligent use of naturally darker areas to support deep, focused work, alongside the creation of fibre-connected screening and review rooms, and a dedicated machine room to handle intensive computing demands.

CINEMA ROOM

The cinema room was a particularly enjoyable space to bring to life. We designed it to be fully adaptable, with the option of natural light or complete blackout, making it just as suited for team huddles as it is for screenings. Acoustic performance was key, so we incorporated highly absorbent materials to ensure exceptional sound quality. We also installed enough fibre to lasso around the moon. It’s a space we’re genuinely proud of.

MEETING
ROOMS

These are spaces we’re buzzed about. We’ve balanced high-performance functionality with a warm, tactile feel by incorporating natural materials throughout, bringing a sense of the outdoors in while embracing the darker zones as purposeful, immersive work environments.

THE PERKS

THE
VIBE

Calm, focused and quietly creative, the space balances technical intensity with warmth. Soft lighting, natural textures and clean lines create a grounded atmosphere, while the open layout encourages collaboration without distraction. It feels purposeful yet relaxed, a place designed for deep work, sharp thinking and seamless teamwork in a studio-like setting.

THE BUILDING

The building offers a strong suite of amenities to support daily working life, including showers, secure bike storage and on-site parking for added convenience. A 24/7 concierge provides round-the-clock support, alongside regular cleaning services and quality coffee on hand, creating a seamless and well-supported workplace experience.

THE
LOCATION

Positioned on Aldersgate Street, this location puts you right between the City and Clerkenwell, with the Barbican just moments away. You’re surrounded by some of London’s best lunch spots, cafés and after-work hangouts, with excellent transport links making it effortlessly connected across town.

YOUR DREAM OFFICE,
WE'LL BUILD IT.

We’re fully aware that different companies need different things from their offices. We know the struggle is real when it comes to the dev-team vs sales-team battle. So much so, that we re-work every office or studio to perfectly suit the needs of our new members.

This might be simple stuff like the ratio of meeting rooms to desks, but it incorporates the fun bits too like a bar area for team hangouts or a games area for downtime. We’re self-proclaimed gurus in office interior design and will guide on colours, layout, floor styles and the branding of your new space too.

We also offer a turn-key product called Sandbox Solutions. This means we’ll discuss what your perfect move looks like and go out and find a new building for you. We then take on the lease ourselves, build the office that perfectly suits your needs and then service it for you. All you need to do is turn up on day one and dive into your brand new ball pit we built for you.

WE RAVE
ABOUT SANDBOX

I don’t think there is a better office space, in a better location, at a better price right now in London. Great transport links, Borough Market for lunch, a personable and friendly team running the building and a great community of startups make it the most happening place to work right now.

Mark, Suri

WE'RE HAPPIER &
MORE ENERGISED

Sandbox is the sunniest office in London. River views, lovely people and a menagerie of dogs make it a joy to be part of this community. From events and socials, to communal spaces, the we have been able to dive into Sandbox life and it has no doubt made us happier and more energised.

Katie, Austin Austin

WE HAVEN'T
LOOKED BACK

The Surreal team have been with Sandbox for 6 months and haven’t looked back. The Sandbox team, regular events & neighbouring businesses means that there is a great community feel around, while at the same time the environment and high spec of the building make it a great place to work. There are also plenty of meeting rooms with an un-capped booking system which is a great touch too!

Jac, Surreal

WE LOVE
COMING TO WORK

We LOVE being a part of the Sandbox community. From the unrivalled views to meeting the other businesses in the office, the proximity to Borough Market to the snazzy meeting rooms we can bring VIP customers to, it’s been a great next step for us as at Good & Proper Tea and we love coming here to work. Most of all the Sandbox team are lovely and always keen to make things possible. The tea’s not bad either…

Emilie, Good and Proper Tea

WOULD 100%
RECCOMEND

Having worked in the London startups scene for over 10 years, I have my fair share of co-working history. Without a doubt, Sandbox has been one of the best experiences, from the start of simple contracts, super friendly staff, legends on the front desk providing more than enough fobs, amazing facilities with great coffee on every floor, cool vibe of a building full of people actually building and of course the incredible events! The team go that extra length to make sure you sorted if its a small thing like a wifi issue to helping find space for us to run 150+ people mixer events always with lets get it done attitude.

Harry, Zebu Digital

WOULDN'T WANT
TO BE ANYWHERE ELSE

We absolutely love Sandbox. The team are great, the spaces are perfect and all the neighbouring brands are like-minded. I did a lot of research and kissed a lot of frogs before we found Sandbox. We couldn’t recommend them enough.

Fabian, Quarter

OUR TEAM
ARE SO HAPPY

As an Environmental Consultancy and a B Corp, commitment to sustainability forms an integral part of our values as a business. The ethos shared across both businesses was clear. After viewing our new office that is right on the bank of the River Thames, I immediately knew our team would be really happy with what the space offers. As a medium-sized company, affordability is a key requirement for us and Sandbox offered us the opportunity to get a much larger space than we could otherwise afford in a brilliant location. The Sandbox team are also very helpful and responsive. I would recommend taking a look around one of their spaces.

Aaron, TylerGrange

INCREDIBLE
LOCATION

We love being at Sandbox. The space is well designed, affordable and has an actual community. We learn so much from, and enjoy being around, all the other companies based here.

Matt, Homethings

WOULDN'T GO
ANYWHERE ELSE

Sandbox Workspace is different, good, different. I feel valued and respected as a tenant rather than the adversarial relationship which is the norm with commercial landlords in London. The operational team is attentive and has a can-do attitude and there is a genuine warmth to all of our interactions. So long as they have space for my business around London Bridge they’ll have a tenant for life.

Rachel, Irvine Partners

WE LOVE
IT HERE

So many workspaces can’t beat Sandbox on a lot of things… we have free meeting rooms, free coffee and free event space, what more could you ask for! We feel valued and love being apart of this community. 

Sam, Sibling Recruitment

LOVELY SPACE
WONDERFUL TEAM

The Sandbox is a hidden gem in the middle of the city, offering the perfect mix of generous office spaces & breakout areas – the star of the show being the top floor communal space and rooftop terrace. It’s the most inviting co-working out there, run by a friendly team who care deeply about making every day in the office a great one. Would highly recommend it to both teams and individuals looking for somewhere to work.
