Where every Source One project starts

Every project we deliver starts the same way. A conversation about what is not working, what needs to change and what the finished space needs to do. From there we develop layout options, work through the detail with the client and agree a design before any work begins on site.

Office design and space planning is not a separate service at Source One – it is how we approach every fit-out and refurbishment we take on, regardless of scale. Getting this stage right is what stops expensive changes later and what gives clients confidence before they commit to the build.

Office design covers more ground than most people expect when they first get in touch. It is not just about how a space looks. It is about how it functions – how people move through it, where teams sit in relation to each other, where meeting rooms need to be, how noise travels, where power and data points need to go, how the space will work in two or three years when the business has changed.

At Source One we use 2D and 3D CAD software to develop accurate layouts and rendered visuals so clients can see exactly how the finished space will work before anything is committed to site. Measurements are taken properly from the start so designs reflect reality, not approximations.

The design process is collaborative. We bring options, clients push back, things get refined. Some projects go through two or three iterations before everyone is happy. That is normal and it is worth the time. A design that everyone genuinely agrees on is far easier to deliver than one that gets changed halfway through the build.

How it works in practice

We start by visiting the space and understanding the brief. What is not working. What needs to stay. What the business needs from the finished environment. Who uses the space and how.

From there we develop initial layout options – typically in 2D first, then 3D visuals for the elements that benefit from them. We talk through the options, take feedback and refine until the layout is right.

Once the design is agreed it becomes the foundation for the project. Partition positions, flooring zones, ceiling grids, lighting layouts, power and data positions, furniture specifications – all of it flows from the agreed plan. That is why getting design right at the start matters so much.

Design is included as part of our service for fit-out and refurbishment projects. It is not a separate charge.

Office Design for Happiness and Productivity

Design in recent projects

A three-storey office refurbishment following a business merger. The design went through several iterations – different layouts, different approaches to the floor configurations – before the right solution emerged.

Lisa and the team kept refining until the layout worked properly for the combined business. As Knights Lowe said:

“We had several iterations on ideas and designs but Lisa and her team tweaked until we had the best layout and best design for our building.”

View Knights Lowe case study

Bringing two very different offices together into one space required careful thinking about how different teams would sit alongside each other.

The design used slatted dividing walls to zone the open plan without closing it down, with acoustic performance built into the meeting room specification from the start.

Layouts evolved during the build as decisions were refined – the design process stayed open throughout rather than being locked down too early.

View Attwells Solicitors case study

A 2,600 square foot refurbishment delivered in five weeks. Lisa led the design process personally, working closely with the client team to develop a layout that reflected the ideaSpace brand and supported the way their community of entrepreneurs actually used the space.

Meeting rooms, breakout areas, open plan offices and a kitchen, all specified and detailed before work started on site.

CAM HR took on the entire fourth floor of their Shoreditch building and asked Source One to create a workspace that reflected their culture and supported their team.

The design included a wellness room, soundproof meeting pods, mood and festoon lighting, acoustic panels, planting and graphics.

A brief where the design thinking mattered as much as the build – getting the atmosphere right required careful consideration of how each area would feel, not just how it would function.

A former chapel with original features that needed to remain central to the finished space rather than be hidden behind a standard office fit-out.

The design had to balance respecting the building’s character with creating a genuinely modern working environment. Curved blind rails to match the room shapes, feature LED lighting inside the dome, ornate panelling alongside contemporary furniture.

A project where design sensitivity made the difference between a good result and a great one.

What good design does for a project

A well-considered layout reduces the number of decisions that need to be made under pressure during the build. It means tradespeople know exactly where partitions, power points and data connections need to go before they start. It means furniture arrives and fits. It means the client is not standing on site making expensive changes because something was not thought through earlier.

It also gives clients confidence. Seeing a 3D visual of the finished space – even an approximate one – is significantly more reassuring than looking at an empty room and trying to imagine what it will become.

For projects that involve a move as well as a refurbishment, good space planning also determines how and when people can be relocated. That sequencing matters.

Complete Project Management

Where design leads

Office design and space planning is the starting point. Once the layout is agreed and the brief is confirmed, we manage the full delivery – partitions, flooring, ceilings, lighting, power and data, furniture, kitchens, decoration, acoustic improvements, move management – the whole project coordinated by the same team who developed the design.

That continuity matters. The people who designed the space are the people who deliver it. There is no handover between a design team and a build team, no gap where things get lost in translation.

See our office fit-out and office refurbishment pages for more on how we manage delivery.

No ask is too big for this dynamic team at Source One who have the vision and expertise to provide exactly what you need in a timely, efficient way. Highly recommended.

FAQs

What happens after the design is agreed?2026-07-03T15:49:07+01:00

We move into delivery. The agreed design becomes the foundation for the project – partition positions, flooring zones, lighting layouts, power and data, furniture specifications. We coordinate all trades and suppliers from that point through to handover.

Can you work with an existing design or brief?2026-07-03T15:48:25+01:00

Yes. Some clients come to us with a clear idea of what they want and just need it developed into a workable plan. Others come with a blank sheet and need us to develop the brief from scratch. We are comfortable with both.

How long does the design process take?2026-07-03T15:47:43+01:00

That depends on the complexity of the project and how many iterations are needed. A straightforward space planning exercise for a smaller office might take a week or two. A larger refurbishment with multiple layout options and client reviews could take four to six weeks. We give a realistic timescale at the start and keep the process moving.

Do you provide 3D visuals?2026-07-03T15:47:05+01:00

Yes. We use 2D and 3D CAD software to produce accurate layouts and rendered visuals. The level of detail depends on the project – some clients want detailed 3D renders, others find 2D floor plans sufficient. We work to whatever level of visual detail is actually useful.

Is office design included in your fit-out and refurbishment service?2026-07-03T15:46:23+01:00

Yes. Design and space planning is included as part of our service for fit-out and refurbishment projects. It is not a separate charge. We develop layouts, produce CAD drawings and work through options with clients as part of how we approach every project.
