The hidden demand for commercial space

Commercial property demand often becomes visible once a business is already looking for a specific plot or a completed unit. Before that point, its needs may be less clearly expressed: a company wants to grow but cannot find a suitable unit; a trade business works across several locations; a local producer needs a different mix of workshop and storage space from what is currently offered. These are signals of possible demand, not proof of a lettable floor area.

Small and medium-sized businesses do not always express their search through standard property channels. Counting only published requirements or current lettings can therefore miss relevant needs. The reverse error is to turn a few responses into a precise forecast. The task is to collect signals systematically, test them and state their limits clearly.

A short survey should go beyond asking for a preferred floor area. It should capture the business task behind the space requirement. A consistent record should include:

• Use: for example workshop, light production, storage, service, trades or a combination. Record office space and customer visits separately.
• Area: separate current space from additional need; allow ranges and distinguish warehouse, production, office and outdoor areas.
• Operations and access: ask about clear height, floor loading, doors, deliveries, power and utilities, access, parking and operating hours where relevant.
• Location: record the preferred municipality or search radius and important links to staff, customers, suppliers and transport infrastructure.
• Timing and commitment: distinguish an active search from a likely expansion and an early, non-binding idea; record timing and who makes the decision.
• Occupancy model: ask whether the business prefers to lease or buy, along with desired term and a voluntary broad cost range. Sensitive financial details should not be required for an initial response.
• Existing space: establish whether the business wants to replace, expand or give up existing space and whether a suitable existing property could work.

Record who responded, when the information was confirmed and whether the same business or requirement may have been counted more than once. Contact details belong in confidential handling, not in a published demand summary.

A simple and transparent classification helps: an active search with a stated timeframe is different from a non-binding growth intention. At minimum, distinguish active search, foreseeable need and early interest. Group responses by use, area range, location and required fit-out.

Remove duplicates. A company can report several requirements; a stated area can replace current accommodation instead of adding to it. Report raw responses, cleaned ranges and the number of confirmed businesses separately. The report should also state response rate, period, survey method and known gaps.

The result is a demand profile, not a project mandate. It may indicate whether flexible smaller units, larger contiguous space or a mix should be examined further. It does not by itself establish a project’s viability or planning permission.

The next step is to compare the profile with available sites and buildings. This includes planning status, access, traffic, energy and utility supply, plot configuration, potential land-use conflicts, availability and whether existing or brownfield sites can be brought back into use. Rents or purchase costs and investment requirements must also fit the intended occupiers.

This sequence helps avoid a common false conclusion: general demand for commercial space does not prove that a particular plot is suitable. A location concept becomes meaningful when actual business requirements and real site conditions are considered together.

The next review connects to site acquisition and project development, brownfield regeneration and the assessment of existing commercial and logistics locations.

Germany’s Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) treats the further development of existing commercial areas and their transformation into productive urban districts as distinct planning tasks. This supports taking existing commercial locations and their potential into account. It does not replace a site-specific demand or feasibility assessment.

1. Scope and search area: state the objective, municipalities, target groups and time period.
2. Method: document channels, questions, responses and the limits of the assessment.
3. Cleaned demand: separate active searches from early signals and report area ranges transparently.
4. Use profile: summarise unit, access, technical and location requirements.
5. Supply comparison: assess existing stock, development sites and known constraints.
6. Next review: identify open points and the required market, planning, environmental and financial checks.

If a scenario uses model numbers, label them as hypothetical and explain the assumptions. They must not read like measured demand or an actual project result.

“Hidden demand” is not an extra area figure that can simply be added to published statistics without checking. It describes requirements that a focused assessment may reveal when businesses are asked about use, timing and specific location conditions. Reliability comes from clear definitions, de-duplication, documented sources and transparent uncertainty.

For municipalities, economic development teams and developers, this creates a stronger starting point for discussion: which groups are actually searching? Which unit types are missing? Which existing or potential sites merit review? Each answer should be tested step by step, including the possibility that market conditions, planning or project economics do not support development.
