The Kitchen · What is it?

The kitchen is the most technically demanding room in a home — water, waste, gas, electricity, ventilation, heat, moisture, and structural load all living inside one finished space. Its failures are rarely about looks; they are decisions made in the wrong order. This course teaches a renovation-first method for taking a kitchen from existing conditions to a contractor-ready specification: survey the space, write the cooking brief, and resolve the systems — plumbing, ventilation, electrical, gas, heated floors — before any cabinetry is drawn. You then plan the layout against those resolved systems and specify surfaces, light, and hardware as one coordinated material story, documented to a standard a contractor can price and build.

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.

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 course emphasizes the importance of proper sequencing in design decisions to avoid common pitfalls and ensure functional, technically sound kitchens. This course covers six modules and approximately twenty-five sections, including reading existing conditions, writing a cooking brief, resolving systems, planning cabinetry, specifying surfaces, and documenting for construction.

Materials and Construction

The course content is based on professional interior design principles and industry standards. It emphasizes resolving plumbing, ventilation, electrical, gas, and heated-floor systems prior to cabinetry design. The approach advocates for coordinating materials such as countertops, splashbacks, flooring, lighting, and hardware into a unified material story. The course teaches how to specify materials with detailed model numbers, edge profiles, and supplier information, ensuring precise procurement for construction.

Dimensions and Specifications

Students learn how to integrate measurements such as linear metres for storage, dimensions for islands and peninsulas, and detailed drawings including plans, elevations, and schedules. The course covers creating measured plans, elevations, cabinetry schedules, appliance schedules, and hardware schedules aligned with realistic project requirements. It enables accurate sizing and positioning of all kitchen elements based on actual equipment inventories and structural constraints.
