When You Walk the Building, There Are No Limitations

An agent calls. The building fits what you are looking for, or it is close enough to be worth an hour, so you go and see it.

What draws you in is usually one of three things. Architectural character, where the building has presence and you can see people wanting to be in it. A blank canvas, where the building itself is unremarkable but the volume and the position give you room to work. Or simply location, where the building is almost incidental to the address.

You read the structure, the volume, the form. The proportions of the spaces, where the light falls, how the building meets the street, and what sits around it. And somewhere in that hour a vision arrives.

At that point you do not understand the constraints of the building. Nor should you.

Why the Unconstrained Walk Matters

That is an odd thing for a development manager to write, so it is worth explaining.

Constraints do not only limit what you can build. They limit what you can imagine.

Once you know the floor to floor heights are tight, the fire strategy is going to be difficult, and the services have nowhere sensible to run, you stop looking at the building and start looking at the problem. You cannot unsee any of it. Every scheme you picture from then on is quietly shaped by what you already know will be hard, and the ambitious version never gets considered at all.

You get one unconstrained look at a building. Only one.

Experience Does Not Cure This and Nor Should It

You might expect enough schemes to knock that out of someone. They do not.

Developers who have been round the cycle many times still walk a building in exactly the same way, and the good ones protect that deliberately. What changes with experience is not the instinct. It is the quality of what they bring with them.

They arrive carrying a bank of references. Buildings seen in other cities. An operator they met who is looking for something nobody is providing. A detail from a scheme that worked. Conversations with people in the industry and, just as often, with people well outside it.

The vision is not generated by the building. It is brought to the building and the building either takes it or it does not.

That is what the first walk round is actually for. It is the moment everything accumulated gets applied to one specific set of walls, and it only happens once.

Use It on the Right Question

Unconstrained is not the same as aimless. The first visit has a job, and the job is to blend the vision with the high level commercial:

What is the end product?

Who does it serve?

Why would they choose this building over the alternatives available to them?

The schemes that work are the ones where the second answer is specific. "Offices" is not an answer. Envisage the occupier, visualise what they are looking for, and determine what they will put up with to get it. Now you have one.

It tells you what the building has to deliver. Just as usefully, it tells you what it does not.

High level is the operative phrase. Nobody is running an appraisal standing in a stairwell, and trying would defeat the point of being there. It is the vision arriving with a rough commercial shape already attached to it, so that everything that follows has something to be tested against.

The Second Visit Is a Different Job

Then you go back, and this time it is deliberately unromantic.

Four things on an existing building are effectively fixed, and between them they decide which uses are possible at all.

Floor to floor heights. You are not changing them and they rule uses in or out before anything else does.

Structural grid and floorplate depth. These set the ceiling on how efficient any layout can ever be. A generous gross area with a poor net to gross is a worse building than a smaller one that works.

Cores, access and means of escape. This is where most conversions quietly die. A change of use brings a different fire strategy with it, and the building has to absorb that within the footprint you have.

Where the services can physically run. Risers, plant space, routes through structural or historic fabric. This frequently reshapes the entire layout and is usually looked at far too late.

Everything else is negotiable. Those four are not.

The same applies outside the building, where it gets less attention than it deserves. Access and servicing, boundaries and rights of way, neighbours who will have a view once the use changes, and what the planning position allows externally. The yard that made the vision work is often the part least able to deliver it.

What Actually Goes Wrong

The failure is not the first visit. It is only ever doing the first visit.

The vision goes into the offer. Then the appraisal. Then the pitch to funders and the brief to the design team. Every repetition hardens it slightly until it stops being something somebody imagined on site and becomes the thing everyone is working towards.

Then the structural survey lands, or the fire strategy, or somebody works out where the services are actually going. By that point changing the vision is no longer a design decision. It is a commercial one, because the appraisal was built on it and sometimes the funding was too.

The Point

Two visits, two questions. What could this be and who is it for. Then what will the building not allow.

Ask them in that order, close together, and the gap between the answers is a design problem. Ask only the first and it becomes a commercial one, usually around month eight.

But the vision has to survive both. There is a point on every refurbishment where everyone is so burdened by what the building will not allow that the original idea disappears into a series of reasonable compromises, each of them individually defensible.

Somebody has to keep hold of what the building was supposed to become. Otherwise what completes bears very little relation to what anyone saw on that first walk round, and the reason the building was worth buying quietly leaves the scheme.
