Buildings are timeless. So too are the dilemmas architects face in their design: what is the building’s place, what does the client want, what will it contain, which structural solution is best suited, and so on. A building is appealing because of its clear structure; it has a recognisable form, and is consistent and well-proportioned in terms of both its construction and layout.
One of the first people to write on this subject was Vitruvius; in the first century BC, he wrote ten books on architecture: a building code avant la lettre! Among other things, this ancient Roman discusses the relationship between firmitas (sturdiness/the structure), utilitas (the building’s purpose) and venustas (beauty). He also discusses, for example, ordinatio (organisation), symmetria (symmetry), eyrytmia (harmony), distributio (the right materials) and decor (appropriateness).
The architectural principles set out below have been around for centuries and have proven their worth:
The relationship between form, function and construction
A building’s appearance (its form) is largely determined by its use and the way it is built (its construction). Yet form is more than just the combination of use and construction: form adds something extra. We therefore believe it is important that use, construction and form complement one another and are logically interrelated.
A good example to illustrate this is Apeldoorn’s town centre. The use of the historic shop premises on Hoofdstraat has changed over the course of the century. The shops have become larger or more garish. The upper floors are no longer always used as living accommodation. You can see that the character of the building has sometimes been obscured by continuous renovation work. The ground floor, with its shop front and advertising, has become visually disconnected from the upper floors. This calls for restoration, so that the upper and lower parts are brought back into balance and the building is once again a unified whole: with its feet firmly on the ground.
Scale and proportions
The proportions of a building form a coherent system. Vitruvius referred to this as ‘the golden ratio’ – a model for determining when something is well-proportioned. Good proportion, however, is broader than just that model. It is something you recognise when you see it, something you have to experiment with, and not something that can be defined by a single rule. It is one of the most elusive aspects of designing a building.
Spaces, volumes and the division of surfaces are interrelated and form a clear hierarchy. A building has a single main form, within which the most important functions are accommodated. Added elements such as outbuildings, bay windows, dormer windows or balconies can be disruptive if they are too dominant. Such secondary structural elements must therefore fit within the structure, dimensions and scale of the building.
The building’s appropriate relationship to the scale of its surroundings, the adjacent buildings, and also the outdoor space (a square or a narrow alley) are key factors in determining how the building fits into the urban context.
Material, texture, colour and light
Material, texture, colour and light make a building visible and tangible. Materials, texture, colour and light support the design of the structure and reflect the character of the building. They also contribute to the building’s harmony with its surroundings. If colours and materials are not in keeping with the design, this detracts from the structure’s expressiveness.
