The Topology Guide · Project Timelines
“How long will it take?” It’s one of the first questions every client asks, and it’s a fair one.
But it’s also the question with the least straightforward answer, because a design timeline isn’t one number, it’s a sequence of dependent stages, several of which sit outside our control entirely.
This guide breaks down exactly how timelines work at Topology, what determines them, and where delays typically come from, so you know what to expect before a project starts.
Part One
The design timeline isn’t one block of time to wait, it’s stages with feedback & deliverables.
Every project moves through distinct phases, and each has its own timeframe.
01
Your layout
We need accurate measurements (or a site measuring survey carried out by us) in order to get started on your layout. If you’ve got a minimal amount of rooms we can turn this round within 3-5 working days, for larger projects around 10 working days. This we can usually nail in 1-2 goes so you’ve got your first deliverable pretty quickly.
02
Concept development
This is where designer hours are spent on space planning, concept boards, material palettes and supplier sourcing. On our Essentials package this sits within a 6 week design window; Full Works includes an additional 2 weeks to accommodate 3D renders and VR walkthroughs. We offer up to 12 weeks for rooms with more than 3 rooms.
03
Client review and feedback
Design time isn’t just us working, it includes the back and forth of you reviewing and approving. This is the stage most commonly underestimated by clients, and the one most likely to extend a timeline. The quicker you reply, the quicker the process takes.
04
Final presentation & shopping lists
Once a scheme is approved, we move into tying up all the information into a neatly packaged up digital presentation on your portal dashboard. This can typically take us a couple of weeks as it’s the most time consuming process.
05
Purchasing, delivery & installation
For Essentials and Full Work Packages, this stage is largely your responsibility with our guidance. For Hybrid+ and On-site Project Management, we coordinate this more directly, which is why those services carry different timeframes entirely.
The kindest thing you can do for your timeline is quick, decisive feedback and have a clear vision

Part Two
Why “design time” has a limit
Our packages include a defined design period, 6 weeks for Essentials and 8 weeks for Full Works. That time is consumed by research, sourcing and concept development, producing layouts, boards, renders and specifications, revisions requested after the initial presentation, and the calls, meetings and correspondence relating to the scheme.
That window keeps moving while you take time to think, gather inspiration or get sign-off from a partner. Therefore it’s important when you onboard with a designer, that you’re readily available for the next 6 -8 weeks to provide feedback. The quicker decisions land, the more of your design time goes into the design itself, which is why prompt feedback genuinely works in your favour.
Part Three
What extends a timeline (and why)
Delayed feedback and approvals
Design is a sequential process. If a floor plan isn’t approved, we can’t finalise furniture placement and we can’t progress with your design. We need your sign off in order to move forwards at all stages.
Scope changes and changes of mind
Adding a room, changing a brief midway, or reconsidering an already approved decision requires rework. Bear this in mind if you’re on a tight timeline!
Product availability and supplier lead times
Some items ship within days. Others, particularly upholstery, bespoke joinery or made to order items, can take 10 to 12 weeks or longer. This is standard across the interior design industry and is outside any designer’s control. We flag long lead time items early precisely so they don’t become a surprise later.
Contractor and trade availability
For projects involving building work, contractor schedules run independently of design schedules. A brilliant contractor could have a three month waitlist!
Part Four
What actually keeps a timeline on track
- Providing accurate measurements, photos and floor plans upfront
- Giving feedback within the agreed review window
- Making decisions once information has been presented, rather than revisiting settled choices
- Having a clear brief & vision
- Knowing your budget at the start
- Understanding that lead times on furniture and materials are set by manufacturers, not designers
In Plain Terms
The honest verdict
Good design takes time because it’s genuinely a sequence: brief, design, approve, source, deliver. Our timelines are built to be realistic rather than optimistic, because a home you’ll live in for years deserves a process that isn’t rushed to hit an arbitrary date. If you have a hard deadline (a house move, an event, a baby arriving), tell us at the very start. We can plan around a deadline.
