Four starting points — one method.
Who is this course for
Working designers
Put a repeatable method under the instinct you already have, and sharpen the process you use every day.
Aspiring designers
Build real professional skills from the ground up. No degree, no prior experience needed.
Project owners
Understand the process well enough to brief sharply, judge the work, and manage the people delivering it.
Homeowners
Approach your own space the way a professional would, and stop guessing on decisions that cost real money.
No credentials required. No experience assumed. Just a commitment to learn how design actually works — because the method is the same for all of you.
How to get the most from this course
Four steps to turn watching into doing.
Set up to work, not just watch
Have pen and paper beside you. This is a course you do, not one you passively watch — the method only sticks when you work it by hand.
Have pen and paper beside you. This is a course you do, not one you passively watch — the method only sticks when you work it by hand.
Take one module at a time
Each module is a complete idea. Work through one per sitting, finish its exercise before moving on, and let it settle rather than racing to the end.
Apply it to a real space as you go
Use your own home, a past project, or an imagined brief. Run each method on something real so it becomes a skill, not just notes.
Expect about a week, at your pace
Most people complete a course in around a week at a relaxed module-a-day rhythm — faster if you push, slower if you savour it. There's no clock; lifetime access means you set the speed.
See the actual work
Not slides. Not tips. These are real pages from inside the courses — the kind of professional documentation The Design Key teaches you to produce.
01
The Brief
Every project begins by defining what it actually is. The Brief teaches the four-dimension framework that stops a project breaking down before it's finished — documented the way a working studio does it.
02
The Moodboard
The difference between a professional moodboard and a Pinterest board, made explicit. You learn to build a strategic visual document that directs a project — not a folder of images you happen to like.
03
The Lighting
Light designed as a system, not chosen as a fixture. The Lighting teaches you to read how daylight enters a room hour by hour, and to plan an artificial scheme that works with it instead of fighting it.
04
The Kitchen
Where the method meets millimetres. The Kitchen takes you into real fabrication-level decisions — joint placement, material limits, service coordination — the technical depth that separates a finished room from a styled one.
FAQ
What is "The Design Key"?
The Design Key is a series of professional methodology courses from Craft'n Build, each covering one core discipline of interior design — the Brief, the Mood Board, the Floor Plan, Lighting, the Kitchen, and more. It teaches how working designers actually think, plan and execute, through the same rigorous framework used in real practice. It's about method, not aesthetics or inspiration.
Who is this for?
Anyone who wants to learn professional interior design method, whatever their starting point — working designers, students and career-changers, homeowners approaching their own space properly, and project owners who need to brief and judge the work. No credentials or prior experience required. The method is the same for everyone.
What do I get, and how do I access it?
Everything is online and yours the moment you buy — instant access, no waiting, nothing shipped. You watch the course in your browser on any device and download the accompanying course material to keep. Access doesn't expire.
Is the course video, text, or both?
Both. Each course combines video lessons with a downloadable written guide and practical exercises, so you can watch, read, and work through the method by hand — which is how it's designed to be learned.
Do I need any experience or special software?
No. The courses assume no prior experience and no expensive software — just a willingness to work through the method. Where a tool is useful, the course shows you accessible options. The method matters more than the software.
How long do I have to complete a course?
As long as you like — access is for life, with no deadline. Most people work through a course in about a week at a relaxed module-a-day pace, faster if they push. You set the speed and can return to the material whenever you need it.
Do I get a certificate?
Yes. Complete any course and you earn a Certificate for that discipline. Complete all twelve and pass the final synthesis exam — which tests your ability to solve real problems across several disciplines at once — and you earn the Design Key Diploma, a credential that reflects mastery of the whole method, not just course completion.
What is "The Master Programme"?
The Master Programme is the full path: all twelve courses together, leading to the Design Key Diploma. You don't commit up front — every single course you take counts toward it. Start with one; the whole programme stays open to you.
Can I just buy one course, or do I have to take the whole series?
Start with a single course — most people do. There's no obligation to take more, but everything you complete counts toward the Master Programme and the Diploma, so a single course is also a first step if you decide to go further.
Do you offer a refund?
Yes — if a course isn't right for you, contact us and we'll make it right.

The Floor Plan — Design Key Series
A floor plan is not a drawing you make at the end of the design process. It is the decision that governs every other decision in a room — and most spatial problems people blame on a lack of creativity are really the result of a missing method. The Floor Plan, part of The Design Key series from Craft'n Build, teaches the complete professional process for designing rooms around how they are actually used, not how they happen to be drawn.
What is professional floor planning?
Professional floor planning is the structured process of analysing a space, resolving how people move through it, assigning a clear function to every area, and producing an accurate, annotated drawing that others can build from. It replaces guesswork and intuition with a repeatable method — the same sequence a working designer follows on every project, whether a single room or a whole home. This course teaches that method from first principles, assuming no prior experience or specialist software.
Read the brief and the site before drawing a line
Every competent plan begins before the pencil moves. You learn how professionals read a brief and survey a site first — understanding the constraints, the existing structure, and the real requirements — so that the plan is a response to the space rather than a shape imposed on it. This spatial-first method is what separates a layout that works from one that merely looks balanced on paper.
Resolve circulation so the space flows
Most awkward rooms are circulation failures. The course shows you how to plan the primary and secondary routes through a space — how people enter, move, and pass between areas — so the floor plan flows rather than fights itself. Getting circulation right early prevents the congestion, dead space, and awkward furniture arrangements that are almost impossible to fix once walls are committed.
Programme every zone before committing it
Before anything is finalised, each area needs a defined purpose. You learn zone programming: assigning a functional role to every part of the plan and resolving the relationships between rooms — which spaces connect, which need separation, which share light or services — so the layout is decided deliberately rather than discovered by accident.
Use proportion and ergonomics as decision tools
A room can measure correctly and still feel wrong. The course teaches proportion and human dimension as active design tools, not afterthoughts — how scale, clearance, and the human body should drive the plan so that every space feels right to be in, not just technically adequate.
Draw to professional standards
A plan only works if others can read it. You learn the drawing conventions professionals rely on — line weights, annotation, and dimensioning — so your floor plan communicates without explanation. These standards are what make the difference between a sketch and a document a contractor can build from.
Present a plan that reads clearly
Finally, the course covers presentation discipline: how to organise and frame a finished floor plan so clients and contractors immediately grasp your spatial decisions, reducing costly misunderstandings before a single wall is built.
Who the Floor Plan course is for
The course is built for anyone who wants to plan space to a professional standard — working designers sharpening their process, students and career-changers building real skills, homeowners approaching a renovation properly, and project owners who need to brief and judge spatial work. No credentials, prior experience, or expensive software are required.
Part of The Design Key
The Floor Plan is one of twelve courses in The Design Key series. Every course you complete counts toward the Master Programme, and the full path leads to the Design Key Diploma. You can start with this single course and go as far as you choose.
