Why Clients Struggle to Read Plans, and How We Fix It
A search-led post in our design thinking series.
1. What happens when you put a 2D plan in front of a client?
Almost every project starts with a site plan Google Earth imagery, drone footage, or an old cadastral plan from the municipality. That's usually a good beginning, because between the client, the municipality, and the builder, everyone has some use for satellite imagery. But not everyone reads that imagery day to day.
So there are early markers to watch for.
Does the client want the drawing orientated toward themselves? Do you turn it so it feels like they're looking at the site the way a person would enter the property? Do they see the orientation? Do they recognise landmarks around the location, the streets, the entry and exit points?
If the answer is yes, the 2D plan is working. The client is engaged, not disorientated, not anxious, not overwhelmed by a task they can't solve.
And if you see any of those frustrations appear, there's a hierarchy of fixes:
Orientate the plan toward the client, so they see themselves as a person entering the premises or driving into the area.
Align it with the streets and explain how the site relates to the drive from their office or home.
Give them landmarks, an intersection with traffic lights where they usually pause, a coffee shop across the street, a familiar shopping centre.
Give them height cues, there's a mountain to our left, an electrical transformer to our right, a cellular tower disguised as a Christmas tree directly behind us.
Once that first site plan is properly orientated, you can explain how the drawing pack is laid out in relation to the site and whether the orientation of the site drawing translates directly to how the rest of the drawings are positioned. If it does, you're ready to walk through it: the exterior, the landscaping, the entry point, the parking, the path one walks, then reception or the front door, the hallway, the mud room, the side kitchen, the back entrance and loading bay.
Then the ground floor. Areas of movement. Areas of transition. Resting areas. The activities that take place. Then the openings where can I see in and out, and when I look out, what do I look onto? Then the transition to the first floor, the second, the third: how do I move between them, and are there multiple points where I can?
2. Why it isn't the client's fault
The strength of a 2D plan is layering. With different line weights, line styles, and line colours, we can stack information for one storey onto a single sheet. And with architecturally trained eyes we distinguish easily between the work of the builder, the electrician, the plumber, the IT specialist, and the shopfitter installing carcasses for store products.
For a client, that's much harder because the client is reading for something else entirely. They're reading for the aesthetics. They're reading to understand the finishes. They'll use the legend and the material board to work out what material goes on what surface. They'll take the ground floor plan plus its elevations and section cuts to understand the ground floor: the plan view for the floor finish and the general flow through space, the interior section elevations for the wall finishes, the exterior elevations for the outside.
They are painting a picture in their mind, using imagination to convert line weights, colours, styles, and hatch patterns into finishes.
That layering exists because it is the architect's job to share as much information as possible with the different contractors, and layering it onto a single elevation is efficient one set of drawings carrying everything. But that efficiency is exactly what overwhelms a client.
Here is the fairest way I can put it. Imagine reading a book where the annotations were numbered, symbolised, and listed alphabetically three separate reference systems, with the explanations held at the back, so you page back and forth for every footnote just to follow the chapter. That's a 2D plan. Five layers of information read simultaneously, with constant paging between legends, material boards, and annotations to understand how the space is crafted.
We can break that apart and give each contractor their own pages but now the client has six sets of drawings for six contractors and six times the information. So where's the line between over-exposing a client to data they don't need, and denying them access to their own project?
3. The fix ladder
3.1 Annotate in plain language
Instead of leaning on symbols, line weights, and colours, annotate the plan in ordinary layman's terms:
This is a wooden floor. The wooden floor is made of oak. The oak is laid in a herringbone pattern. A herringbone pattern is two pieces of wood offset from each other at 45 degrees, and it works best set perpendicular to the direction of light entering the room, in this case, along the length of the room.
Then put a small sample from the material board right next to that annotation, cropped into a circle or square. Now the information lives directly on the plan, at the part of the drawing it describes, and the client reads the annotation beside the hatch instead of hunting for it. Do the same for walls, finishes, entrances, exits, back of house.
3.2 Generate a 3D plan alongside every 2D plan
If your stack is SketchUp with LayOut, you can instruct LayOut to generate both a 2D technical plan and a 3D technical plan every time: the 2D as a parallel projection, the 3D as a plan in perspective.
That perspective plan reads as a bird's-eye view perpendicular to the floor. Suddenly the wall isn't a line thickness, it's a vertical element you can see. The client feels like they're in a drone hovering above the ground floor, looking down into the building: wall finishes, what stands or hangs on those walls, the floor and its attributes.
The one caveat: a perspective plan radiates from its centre, so there's more distortion toward the edges.
3.3 Model in 3D first, and let the drawings come out of it
Here's the deeper shift. Instead of creating a 2D set of plans from a 2D model, we create a 3D model and generate a 3D and 2D set of plans from it.
Building a 3D model from the 2D plans is putting the cart before the horse. Yes, a 3D model can spit out 2D drawings but that was never the point of the 3D model. The 3D model, with its clash detection, its walkthroughs, renders, and fly-throughs, carries far more information and insight than a 2D plan can deliver with the help of the client's imagination.
So we produce every plan, ceiling plan, interior and exterior elevation, and section cut in both full parallel-projection 2D and full perspective 3D. Beside or beneath the technical drawing sits the 3D view of the same area — fully colourised and texturised, ambient occlusion, PBR materials, a semi-realistic render.
That same information can then travel further: as an animation, as a walkthrough of the building, or embedded into the Gaussian splat of the site visit, where the newly designed rooms sit inside the actual captured environment. In a single walkthrough you can transition from the splat, into the drawing, and back into the 3D walkthrough in another part of the site.
The trade-off is discipline. The information has to be embedded in the SketchUp model, so it becomes our role to build the model as thoroughly as possible LOD 400 to use the LayOut documentation template systematically to generate the plans, elevations, and section cuts, and then to moderate and curate the outputs the template produces.
After that curation stage, we can assess the quality of each drawing for its audience: the contractor, the municipality, and the client. Instead of feeling overwhelmed by the task of producing multiple sets of drawings, the modular template structure lets us generate drawing packs with an eye on who wants to use what, for what.
3.4 Draw the furniture at its own scale
Plans cover the whole building or the whole room but the room contains specific fixtures, and those deserve their own treatment.
Our LayOut templates always carry 1:10, 1:20, and 1:30 sheets for setting up an individual object: an isometric 3D view alongside its plans and section cuts. That way you can present each unique piece of furniture you're incorporating into the space on its own terms.
It gives the conversation a natural order: first the plan, then the fixtures within the plan.
4. How scans keep the drawings honest
Look back at the Jameson project we covered earlier this year. It was extremely time-sensitive three and a half months from first site visit to the deliverable for the start of the event.
We were handed information before we went to site. As soon as we loaded that SketchUp model into our working template and assessed the site, we realised something was off with the scale and we weren't sure whether the person who supplied it had drawn it that way deliberately.
SketchUp has a wonderful set of tools for incorporating a real-life location: File → Add Location, then follow the prompts, and a whole set of 2D and 3D mapping layers becomes available. We imported a 2D map the client had already drawn most of the 3D structures and quickly saw that the spaces were modelled at roughly 30% of actual size. Scaling by a factor of three fixed it.
A day or so later we had our first virtual call, and no sarcastic comment was needed. No "why did you draw this at the wrong scale?" Just a genuine question about the client's starting process: thank you for the drawings how did you begin? What was the basis? What information did the historic foundation who look after this monument give you, and how did you apply it in SketchUp? Were you aware it wasn't quite to scale?
The answer surfaced quickly. The historical foundation had shared old CAD drawings, those drawings weren't necessarily to scale, and on import into SketchUp it wasn't clear what the scale would become. And all he actually needed at that point was a general massing to understand how the stage would fit into the inner court of the castle.
That's what 3D scans do, whether it's Gaussian splatting, LiDAR data, or what you pull from Google Earth: they create honesty in the data. None of our drawings, none of our 3D models, are drawn in isolation from what's out there in the world. We draw the future conditions on top of a layer of reality not on sinking sand.
From the comfort of the office, you're not creating an abstract euphoria. You're creating a faithful, courageous 3D model of what can be achieved on site with the right financing, stakeholders, and contractors.
And that honesty, carried from the start, prevents the snippy little arguments later. Why didn't you see that the municipal fire hydrant sits three metres off the building line, so we can't put parking in front?Why didn't you see that the neighbour's lounge window looks straight onto our pool area, couldn't we have orientated the building for more privacy? None of these are hard questions. They're just very hard to see without reality in the model. In the splat, we can demonstrate them to the client early, and to the contractor when we present.
5. What changes in approvals and sign-off speed
When we present in 3D, it's tempting to think we've cleared the hurdle. That may be a little optimistic a 3D plan is still, in the client's eyes, an abstract line drawing
Don't forget how much time you've spent inside this space. You and I have spent hours, maybe days, drawing a site we now regard as home. At the start of a project we weren't familiar with it either; by the end we're embedded in it and completely comfortable talking it through.
The client hasn't had that. They may have driven past the site a few times on a Saturday afternoon with a takeaway coffee and a spouse or fellow investor. Beyond that, they know the finances and the investment they need to make. They may know the product they want to sell there or the life they want to live there. They may have brought two sketches, some AI renders, a Pinterest mood board, an image from a book, or a childhood dream of a future they've always wanted to build. But they have not spent the hours in the drawings that you have.
So: take your time. Present in 3D. Then, when technical sign-offs are needed between you, the contractors, and the municipality, transition slowly from 3D into 2D or into 2.5D, showing elevations and section cuts in perspective rather than fully flat. Show that transition alongside the 3D.
And if the relationship is comfortable enough, present live: open SketchUp without the bells and whistles of every plugin, in presentation mode, clean, with only the navigation toolbar visible. That way you enter a shared language of the 3D model, and the 3D model doesn't need re-translating.
But don't make the mistake of presenting the 2D plan as your first and foremost way of communicating. Unlike you, the client does not think in line weights and hatches. They experience the world as a consumer, or an accountant, or a chemist, or a person of faith, or through statistics. They have eyes that see in an entirely different way.
And part of the reason they contracted you is to take away the pain of needing eyes that see the way yours do the way you see for municipal approval, the way you see to take risk away from the contractor building it, the way you see to design fluidly where they would struggle to follow what's going on.
