The concept is approved. Now it gets resolved properly, so the approvals and the engineering have something solid to work from.
What is the design development stage? It's where the idea gets proved buildable. The concept has been approved, the emails have thinned out, and the drawings arriving now carry dimensions, levels and notes — because they're written for the people who will build your house rather than the people imagining it. That's the design becoming real.
Levels get checked against the survey. The roof geometry gets resolved so the gutters fall where they should. The structure gets thought through, the drainage gets a route, and the consultants start work that has to be reconciled against the design and against each other.
All of it is far cheaper to resolve now than later. A problem found on a drawing costs an afternoon — the same problem found on site costs a beam through the middle of the window that made the room work.
The drawings get more technical through this stage, and that's the project getting more certain.
Design development takes the agreed concept to the resolution the approvals and the engineering need — structure, levels, drainage, roof geometry, constructability and a schedule of proposed materials and finishes, reconciled into one coordinated set.
Confidence that the beautiful thing is real, not just a picture. The drawings get more technical through this stage, and that's the project getting more certain — every line that goes on is a question someone has answered for you, so it isn't answered in a hurry on site.
A concept can go more or less straight to a builder, and on simple work that's fine. On anything with structure in it the resolving still has to happen — it just happens later, on site, at the pace the build demands.
This is where the house stops being an idea and becomes a set of decisions other people can act on. I resolve structure, levels, drainage and roof geometry on paper, and I brief and coordinate the consultants so their work agrees with the design and with each other. The drawings get more technical as this goes on, which is them getting more useful — a technical drawing is the design made precise enough to build. I'll keep you posted through it, including when the honest report is that everything is going to plan.
It's where the agreed concept is taken to the resolution the approvals and the engineering need — developing the approved design, briefing and coordinating the consultants, preparing a schedule of proposed materials and finishes, and checking the design back against the budget. It's the stage where the house becomes a set of decisions other people can act on.
Each project is different, and I'll give you a realistic programme for yours and update it as we go. Two things stretch this stage: waiting on a consultant, and waiting on a decision from you. A survey that hasn't been ordered stops the engineer, and the engineer stops everything downstream.
Ask, directly. A reasonable architect will answer with a written programme, dates against deliverables, and a straight account of what's being waited on and from whom. Much of this stage is coordination and approval preparation, which produces a great deal of resolution and not much that photographs well. The stages that feel slow are usually the ones preventing a longer delay later.
You can, and I'd rather you asked than sat there wondering. They'll be work in progress — options still open, notes to myself in the margins — which is normal for a set mid-flight. What tends to help more is a regular note from me on where things are.
There's plenty to look at — it just isn't a picture of the finished house. You're paying for resolution: every level checked, every junction thought through, every consultant's work reconciled with the rest. Ask me what the deliverables are at the end of the stage and what has to be true before it can close.
If you would rather start small, the First Sketch Session is two hours at your place. You keep the sketches, and there is no obligation afterwards.
