What is a sketch design?
A sketch design (Dutch: schetsontwerp, SO), also called a concept design, is the first real design stage of a building project. The architect produces sketches that make the client’s wishes visible and explore what is and is not possible. It is above all a discussion tool between architect and client.
In a typical design process the stages follow each other like this:
- brief and requirements;
- sketch or concept design;
- developed or preliminary design;
- final design;
- technical design and specifications, followed by construction.
In the UK, the RIBA Plan of Work calls this stage Concept Design (Stage 2).
What does a sketch design cover?
- the client’s wishes (brief, atmosphere, mood board, rough budget);
- the overall form, massing and main layout of the building;
- first floor plans and elevations, sometimes already in 3D;
- the site: orientation to the sun, plot, surroundings;
- planning constraints such as zoning rules, design codes and maximum height;
- how spaces relate to each other, for example bathroom near the bedrooms;
- any sustainability ambitions.
An important secondary aim is to check whether the original wishes and the budget still match. Several options are often compared side by side at this stage.
Application
For homeowners planning a build or extension, the sketch design is the moment to set the direction. Choices made now are cheap to change; later on, changes become ever more expensive.
Tips:
- Come prepared: summarise your key wishes on one page, with keywords and a few example photos.
- Check early: find out whether the plan fits local planning rules. Many planning authorities offer pre-application advice.
- Watch the budget: ask for a rough cost estimate per option.
- Record decisions: make sure the chosen option and decisions are written down before the next design stage starts.
