The peripheral district paradox

When we talk about the compact city, what usually comes to mind are inner cities as the exemplar of density, mixed functions and good transport. But what about a district that is itself a product of urban sprawl? Genuine professional dilemmas line up around compacting a peripheral district — and it is worth stating them openly, because only then can half-measures be avoided.

1.The paradox we start from

Suburban peripheral districts typically exist precisely because the city did not develop in a compact way. Their present form and role were created by sprawling, low-intensity development — that is, by exactly what runs counter to the principles of the compact city. Hence the question: is it not a self-contradiction to make these areas more compact after the fact?

Answering it first requires an important distinction. Peripheral existence is not in itself a problem, and the suburban way of life is a perfectly legitimate choice, with logical arguments. The compact model should therefore be treated not as a normative command but as a development direction adapted to the specific place. The question is not "let us densify everything," but where and to what extent.

2.Where does the sprawl disappear to?

One of the most serious risks is that densification does not eliminate the problem but only relocates it. If services and population concentrate around a peripheral node, it may become a new "centre of gravity" that can even generate further dependency relationships and additional agglomeration sprawl. In such cases the goal is not achieved at the macro level, since the externalities arising from the centre–periphery relationship do not disappear, they merely appear elsewhere in space.

Linked to this is also the danger of intensifying dependence on the centre. The outer districts are largely residential-dominant, while jobs and higher-order services are concentrated in the inner districts. If compact interventions "merely" make the inner city easier to reach, this may paradoxically increase the pressure to commute — unless a genuine system of local sub-centres is built alongside.

The solution is not to densify the district as a whole, but to strengthen a few well-chosen nodes while preserving the suburban character.

3.The question of scale

A Budapest peripheral district is often larger in extent than many inner cities. District 18, for example, is about nine times the area of the inner city within the Grand Boulevard — here full, all-encompassing densification is not only unrealistic but also undesirable. The realistic path is node-based compactness: we develop functional densification and accessibility in a few sub-centres, in a hierarchical yet network-organised system. Compactness is thus not a condition covering the district as a whole, but a characteristic that appears at specific points or along lines.

4.Money, market and politics

Spatial-structural transformations require significant capital investment, while the return — lower operating costs, more efficient public services — often materialises only decades later. The time horizon of urban development typically exceeds a single electoral cycle, whereas decision-making generally thinks in electoral cycles, so short-term political risk and long-term benefit become separated in time.

The market does not always help either, since investors often fail to see the potential in the outer districts, or indeed carry out investments that reinforce sprawl. Capacity constraints may be added to this — the institutional and utility networks of part of the suburban areas are dimensioned for a low population, so densification must go hand in hand with proportionate network development, otherwise per-capita provision deteriorates.

5.Identity and resistance

Peripheral character is not merely a form of development but also an identity-shaping factor. A significant share of residents have deliberately chosen a family-house, greener living environment, so they easily experience densification as a transformation of their way of life. This is partly where the NIMBY phenomenon ("not in my backyard") comes from, where the resident often has no objection in principle to development, but resistance is triggered by change to their immediate living environment. Added to this is the risk of a shift in social composition and a decline in local green surfaces.

6.The interests of governance levels

Budapest's two-tier local government adds a particular difficulty, since the capital and the district are often simultaneously responsible for developments, and their intentions do not always coincide. Compact development in a peripheral district requires infrastructure and institutional expansion that often needs capital-city or state funding; in its absence, interventions may be delayed, or fragmented, ineffective compromises result.
