Lessons from 30 Years in Practice

Eight short lessons I keep coming back to โ€” on design, on running an office, and on getting through a career with your sanity intact.

I graduated from Nelson Mandela University in 1993. That’s more than thirty years of drawing, arguing with municipalities, standing on building sites in the rain and running an architectural practice in the Eastern Cape. Over the past few months I’ve been recording short videos on some of the things that time has taught me. None of them are about building regulations or floor areas. They’re about the habits of mind that, in my experience, make the difference between a practice โ€” and a life โ€” that works and one that doesn’t.

Here they are, gathered in one place.

1. Know what you want

A design visualised before a brick is laid: knowing what you want, in detail.

Ask anyone whether they know what they want and they’ll say “of course.” But listen carefully to the answer and it’s almost always a list of what they don’t want.

In politics we don’t want corruption, we don’t want sewage running down the street, we don’t want potholes. In our own lives we say we want a holiday โ€” but what we really mean is that we don’t want to be at our desks. That’s not a want. That’s an escape.

Architects are actually well trained in this. Our whole job is to work out, in great detail and ahead of time, exactly what it is we do want: plans, sections, elevations, window and door schedules, ironmongery schedules. The detail is what makes it possible to bring the thing into the world.

But even with buildings it’s easy to slip back into the negative. We don’t want something illegal. We don’t want something a burglar can break into. We don’t want the roof to leak. Fine โ€” once all of that is dealt with, what do you want? What is the beautiful thing this building needs to be to strike that other chord?

There’s so much noise about what we don’t want that there’s hardly time left to ask the real question. So take the time. What do you want?

2. File it so someone else can find it

People sometimes ask what the difference is between working on your own and working in a team. There are many, but here’s a simple one: when you work alone you can put things anywhere, because you’ll remember where they are. In a team, you have to put things where someone else will find them.

In our office everything that arrives on paper โ€” a municipal “jacket” of approved plans, a comment sheet, an informal town planning enquiry โ€” gets scanned the day it comes in. It goes into the project folder, which is always arranged the same way (documents, drawings, PDFs, proposals), and it’s saved with a searchable name that includes what it is and the erf number.

Yes, this is boring. I know. But do you know what’s more boring? Spending two days hunting for a document you know you had somewhere โ€” usually because the colleague who had it has moved on to another job and you’ve picked the project up from where they left off.

Good filing is a form of respect for the people you work with.

3. Speak your mind

Round the table with the plans
Round the table with the plans: everyone needs a voice in the room.

Develop opinions. Develop preferences. Know what you like and what you don’t, and live it out.

It sounds obvious. Very few people actually do it.

I’ve been fortunate to spend time with some very wealthy people and some very poor people, and here’s what I’ve noticed: both of them say what they think. It’s the people in the middle who are afraid to talk. Afraid they won’t be invited to the next braai. Afraid their friends won’t like it. Afraid of what the boss will say, or that they’ll lose the business deal. So they never form an opinion at all.

Our political parties, our corporations and our government departments are full of people stuck in that middle โ€” always guessing what they’re supposed to say rather than saying what they think.

For an architect this matters enormously. Clients don’t pay us to reflect their own uncertainty back at them. They pay for a considered point of view. Find the courage. If things go wrong, you’ll find a way. But have a voice.

4. Ask who “they” are

“What will they say?” โ€” if I fail, if they see me dressed like that, if I’m seen with that person. Most of the time we’re not even aware we’re asking it. The script just runs quietly in the background.

So here’s an exercise. Sit down with your coffee and write down who “they” actually are. Just the top three names. Then ask yourself honestly: if those three people disapproved of how I trim my nails, or the dent in my bakkie, or who I had a drink with โ€” would I really be that upset?

The truth is people aren’t thinking about you much at all. They’re worried about getting to the end of the month and paying their own bills. But left uninterrogated, that “what will they say?” ghost creates a low-grade anxiety that leads to poor decisions โ€” in business, in relationships and in life. Name the ghost, and it tends to disappear.

5. Be unreasonable (sometimes)

Brick piers and a domed rooflight
Brick piers and a domed rooflight: buildings that began as somebodyโ€™s unreasonable idea.

I don’t mean be rude, or obnoxious, or an idiot. I mean that “being reasonable” only uses one part of your brain โ€” the conscious, rational part that can follow its own thinking step by step. It’s a small part of your total capacity.

The rest of your brain is doing extraordinarily intelligent things you’re not aware of. It keeps your heart beating. It runs your pancreas (wherever that is). And every now and then it sends up a feeling โ€” a hunch, an urge, an idea that the sensible “primary school” part of your mind immediately dismisses as unreasonable.

In design, some of the best moves start exactly that way. Set yourself guard rails, by all means. But don’t let the reasonable voice overrule you every time. If you’re not ready to act on the unreasonable suggestion, at least start by listening to it.

6. You will not succeed 100% of the time

Everybody knows this. And yet when we fail, there’s still a voice somewhere deep inside that beats us up for it.

Think of the most capable people you can name. How many rockets did SpaceX blow up before one landed? Maradona was the greatest footballer of all time and still handled the ball now and then. Even the God of the Sunday-school Bible, in that wonderful metaphor, made Adam, realised he was lonely, and had to try again.

None of them would gain anything by beating themselves up. Neither will you.

In fact, if you are succeeding 100% of the time, it’s a warning sign. It means you’re not attempting anything that could possibly fail โ€” and that means you’re not trying hard enough. Every project worth doing carries the risk of getting something wrong.

7. An expectation is a prophecy

Mid-move
Mid-move: an empty floor, boxes and rolled-up carpet. Reality rarely matches the plan.

You’re not entitled to anything. Not the car, not the house, not even tomorrow. A tsunami could wash it all away.

That sounds harsh, but it’s actually liberating, because most of what upsets us isn’t reality โ€” it’s the gap between reality and what we expected. We expected to be married with three children by thirty. We expected the degree to lead to a job. We expected the road not to have a pothole that would wreck the suspension, the refuse to be collected, nobody to pick our pocket.

An expectation is really a prophecy: a little story we tell ourselves about a future without potholes, pickpockets or a bad economy. And when the world doesn’t follow the script, we’re miserable.

You can’t control the economy or the municipality. You can control whether you make prophecies. In thirty years of dealing with planning departments, contractors and budgets, I’ve found that letting go of entitlement is one of the most practical things you can do โ€” for your projects and for yourself.

8. Adaptability is a superpower

A site meeting in a stripped-out space, working out what it could become
A site meeting in a stripped-out space, working out what it could become.

You are not a tree. You can move. You can try new things, eat new things, change direction. That ability to adapt โ€” to experiment, get feedback from the world and adjust โ€” is what sets our species apart.

Yet we’re quick to criticise people who change course, whether it’s a colleague who switches careers or a public figure who changes parties. I suspect much of that criticism is envy: we haven’t given ourselves permission to change. Nobody has to stay in the same profession, or the same job, or the same way of doing things for their whole life. The feudal system wanted peasants to believe they could never be anything else. We don’t have to believe that story.

Our profession is changing fast right now. The architects who thrive will be the ones who treat change as an experiment rather than a threat. You may succeed, you may fail โ€” but you’ll learn which way to go.

Thirty years on

Looking back, very little of what has made a difference in my career came from technical knowledge alone. It came from knowing what I wanted, saying what I thought, not worrying too much about “them,” trusting the odd unreasonable idea, forgiving myself the failures, letting go of expectations, staying willing to change โ€” and filing things properly so the rest of the team could find them.

If any of these resonate with you, or if you’ve learnt different lessons from your own years in practice, I’d love to hear them.

How to Find Contours for Any Site in South Africa

One of the most common frustrations in early-stage architectural and engineering work is tracking down reliable contour data. You check Google Earth. You dig through your metro’s GIS portal. You try Google Maps. And you come up empty โ€” or close enough to it that the data isn’t useful.

Here’s a tool that solves that problem.


One Map: Contours for Any South African Site

One Map (onemap.co.za) is a subscription-based mapping service with a free tier that gives you access to contour overlays for sites across South Africa. For initial feasibility and concept work, it’s one of the most practical tools available locally.

The contours are displayed at 5 metre intervals โ€” enough resolution for early site analysis, section studies, and understanding the general topography of a site before you’ve commissioned a survey.


How to Turn Contours On

The interface is a little clunky, so here’s the exact sequence:

  1. Open your site in One Map.
  2. Click Workspace and Layers in the side panel.
  3. Select Overlays.
  4. Find NGI and enable Relief Lines.

You can toggle this layer on and off as needed. Once it’s active, you’ll see contour lines across your site with elevation values labelled directly on the map.


What It’s Good For

  • Early site analysis โ€” understanding slope, drainage direction, and level changes before a survey is commissioned.
  • Concept design โ€” informing split-level decisions, retaining wall locations, and building placement.
  • Client presentations โ€” a quick visual read of the topography that non-technical clients can follow.
  • Rural and peri-urban sites โ€” particularly useful where municipal GIS data is sparse or outdated.

A Word of Caution

One Map contours are useful for initial thinking and planning. They are not a substitute for a registered land surveyor’s certified contours, which you’ll need before submitting for local authority approval or moving into detailed design. Treat this data as a starting point, not a deliverable.


Other Sources Worth Knowing

If One Map doesn’t suit your workflow, a few alternatives are worth having in your toolkit:

  • Chief Directorate: National Geo-spatial Information (NGI) โ€” the underlying data source One Map draws from. You can sometimes download raw DXF or shapefile contours directly for use in CAD or Revit.
  • SANSA Earth Observation โ€” useful for large rural sites where NGI coverage becomes patchy.
  • Google Earth Pro (free desktop app) โ€” the elevation profile tool along a path can be handy for quick cross-sections, and you can export KMZ overlays.

Whenever we find a tool that saves time on the unglamorous parts of the job, we’ll share it here. If you have your own go-to resources for site data in South Africa, drop them in the comments โ€” we’d like to know what others are using.

Coverage, Floor Area, and FSI Explained โ€” What Every Property Owner Needs to Know

https://youtu.be/o9sdb4KF7Yk

If you’re planning to build, extend, or develop a property in South Africa, you’ve probably come across terms like coverage, floor area, and FSI in your dealings with the local authority. Whether you’re in Cape Town, George, Nelson Mandela Bay, or dealing with your local municipality, they’ll ask you about these figures โ€” and getting them wrong can delay or derail your project.

Here’s a simple breakdown of what each term means.

Coverage: How Much of Your Site Are You Building On?

Coverage refers to the footprint of your building โ€” in other words, how much of your site is physically covered by the structure when you look at it from above.

Let’s say you have a 1,000 mยฒ site and your building covers 500 mยฒ of it. Your coverage is 50%.

This matters because your zoning scheme sets a maximum coverage limit for your property. It also dictates your building lines (how close to the boundary you can build) and what the property can be used for. Exceed the coverage limit and your plans won’t be approved.

Floor Area: The Total Space Across All Storeys

Floor area is different from coverage because it accounts for every level of the building. If your 500 mยฒ footprint has two storeys, your total floor area is 1,000 mยฒ. Coverage stays the same โ€” the building still only covers 500 mยฒ of the ground โ€” but the floor area doubles.

This is why multi-storey buildings can provide significantly more usable space without necessarily exceeding coverage limits.

FSI: Floor Space Index

FSI stands for Floor Space Index, and it’s the ratio that controls the maximum total floor area you’re allowed to build on a given site.

The formula is simple:

Maximum Floor Area = Site Area ร— FSI

So if you have a 1,000 mยฒ site with an FSI of 2, you’re permitted to build up to 2,000 mยฒ of floor space in total. You can find your property’s FSI in your zoning certificate or by submitting a town planning inquiry to your local municipality.

FSI is particularly useful on multi-storey developments, where you want to maximise the building’s potential without exceeding what the zoning allows.

How to Determine the Age of a Building (When You Don’t Have Approved Plans)

If you’re an architect or built environment professional working on a heritage permit โ€” or even a routine building plan submission โ€” you’ll need to know whether the building you’re working on is older than 60 years.

Why does it matter? Because under the National Heritage Act, any building older than 60 years (or any site on which such a building stands) is protected. That means you need to declare the building’s age in your plans, and getting it wrong has real consequences.

The Obvious Starting Point: Approved Plans

Approved municipal plans are your best source. They’ll tell you when a building was constructed. If you can get them, go to the municipality and request the approved plans on record โ€” that’s your most reliable evidence.

But what if there are no approved plans? That’s where it gets trickier, and where many practitioners get stuck.

The Fallback: The Survey Diagram and General Plan Number

If approved plans aren’t available, look at the survey diagram for the property. The survey diagram records when the land was first surveyed, and crucially, it contains a General Plan number โ€” which tells you when that township or subdivision was established.

For example, a General Plan dated 1983 tells you the land was subdivided in 1983. That gives you a definitive earliest possible date for any buildings on it.

This is a document you can attach to your heritage permit application or building plan submission as supporting evidence of age.

An Important Nuance

The General Plan date tells you when the land was subdivided โ€” not necessarily when the building was constructed. A General Plan from 1984, for instance, doesn’t mean the building was built that year. Construction may have followed a decade later.

That’s why the survey diagram works best as a floor โ€” it establishes the earliest the building could have been built. Pair it with approved plans wherever possible to narrow it down further.

In Summary

SourceWhat it tells you
Approved municipal plansActual construction date โ€” most reliable
Survey diagram / General Plan numberDate the land was subdivided โ€” useful fallback

When approved plans aren’t on record, the survey diagram is a legitimate and useful document to support your application. Know where to find it, and keep it in your toolkit.

The Easy-Peasy Guttering System: Rainwater Harvesting with a 75mm Downpipe

I want to show you a very simple guttering system โ€” an easy-peasy guttering system you can do really quickly when you’re working with corrugated iron.

Why is this important? Because people are sometimes too fast to leave projects, to let somebody else take over โ€” to let somebody else take our freedom away from us by telling us it’s too complicated. It isn’t.

The Idea

The whole system is built around a simple 75mm PVC downpipe โ€” the standard kind you’ll get at any Builders Warehouse or Home Depot, along with the little elbows to match.

The trick is this: you split a length of downpipe down the side, then open it up and clip it onto the end of the roof sheet, where it acts as a gutter. The corrugated iron edge sits inside the split pipe, and the rainwater running off the roof feeds straight into it.

I’m not the guy who thought this up โ€” I’ve seen other guys do it before, including a very good friend of mine who has used it on very nice buildings.

The Tools

Nothing fancy: a pair of gloves, a cordless hand drill (mine’s a 14-volt), a crosscut saw, and a level โ€” I like to use a Stanley.

I cut the slit on a table saw, but you don’t need one โ€” you can do it with a handsaw. One warning: be careful of the sharp edges of the corrugated iron. I don’t want to create any accidents with this.

Putting It Together

Split the pipe, open it up, and work it onto the edge of the roof sheet โ€” I prefer feeding the thick end on first. At the corner, an unsplit elbow clamps over the split section, which also helps grip the gutter more firmly around the sheet. Then secure it in place with a screw from your hand drill โ€” that’s all you need to hold the downpipe in position. Do that at each corner and you’re away.

At the bottom end, the downpipe runs into a 200-litre drum โ€” ours was rescued from a dump site; it used to belong to Castrol, but now it belongs to Pebble Spring Farm. From the drum, a few attachments let us run the water off to feed the chickens and the rabbits.

It’s really that easy.

Do the Numbers

Don’t be confused by the size of this very little project โ€” it’s a rabbit hutch and a chicken coop we built here. But the maths is worth looking at.

This little piece of roof is 1 metre wide by 1.5 metres โ€” 3 square metres of roof sheet in total. Here in Port Elizabeth, at 34 degrees south near the coast, we get about 600 to 700mm of rain per year. Over 3 square metres, that’s around 2 kilolitres of water a year โ€” an average of about 5 or 6 litres a day.

The chickens and rabbits are not going to use 5 litres a day. This little unit becomes completely self-sustaining โ€” and the whole system is going to expand to 10, 15, 20 units.

Keep It Small, Keep It Free

Don’t try this on big industrial operations. I’m talking about home projects โ€” a little shed, a little house, a little cottage, a chicken coop, that kind of stuff.

Tell me how it works for you in your environment. We’re looking for easy things, we’re looking for cheap things, we’re looking for stuff you can do yourself โ€” to set yourself free.
