For a company expanding into Spain, choosing premises can become a race between attractive locations. The best-looking unit is not necessarily the easiest place to open. Physical constraints, shared-building arrangements and the proposed business activity can matter more than the finish visible during a viewing.

Evaluate the property as an operating platform. Establish what your business needs, test that brief against the premises, then estimate the investment and time required to open. This sequence gives the acquisition team something more useful than a simple comparison of asking prices.

Translate the business concept into a premises brief

Describe customer visits, staff, hours, equipment, deliveries, storage and any specific process. A retail showroom, medical practice, food business and office may all appear in searches for commercial property, but their practical requirements differ.

If a brand team has a standard international layout, ask which elements are essential and which can adapt. A format designed around another country's building stock may need adjustment. The local technical team should receive equipment schedules and operational requirements before creating a fit-out proposal.

Use this brief when asking about the local approval or notification route. Request available records of the previous activity, while having your adviser assess the proposed operation in its own right. A seller's statement that a unit has operated commercially is not a complete answer.

Walk through an actual working day

On the plan, trace a customer visit, staff movement, delivery and waste collection. Identify clashes and hidden space needs. A unit can have an adequate total area but leave too little usable space after circulation, storage and services are accommodated.

For a simple example, a showroom might receive bulky deliveries through the same entrance used by customers. The operational solution could require different scheduling, a changed layout or another property. Discovering that limitation before acquisition is more valuable than refining the display design.

  • Measure the entrance and inspect level changes.
  • Confirm available height where services would run.
  • Locate water, drainage, power and equipment positions.
  • Check the relationship with neighbouring occupiers.
  • Identify areas shown in marketing material that need documentary clarification.

Investigate the shared building

A ground-floor unit can depend on roof space, shafts, courtyards or façade positions outside its private boundaries. Obtain the relevant ownership documents, community rules, meeting records and planned expenditure. Mark proposed interventions on a drawing for the legal and technical teams.

Work affecting common elements requires review under the applicable horizontal-property regime. The references include the national Horizontal Property Act and, in Catalonia, the Catalan Civil Code's property provisions.

Keep the private-rights review alongside the municipal process. The general guide to building-community costs and records provides additional questions, even though its purchase example focuses on apartments.

The Spanish Building Code addresses interventions in existing buildings within its stated scope. Ask the designer to explain the applicable requirements and how the proposal meets them, referring to Article 2 of the CTE.

Do not allow a promising interior rendering to stand in for an installation strategy. A proposed equipment position is only useful when its routes, servicing and surrounding rights have also been considered.

Prepare an acquisition-to-opening budget

Include the property, transaction expenditure, investigation, design, local procedures, enabling works, fit-out, equipment, testing and relocation. Add any overlapping occupation costs. Show the opening date beside the cash requirement because a cheaper adaptation can be poor value if it misses a critical trading period.

VAT treatment and deduction depend on the transaction and business use. Have the adviser check the relevant provisions of the VAT Act, including Articles 20 and 92–95, before assuming an amount will be recoverable.

Require fit-out bidders to price the same information. Use the construction quotation comparison guide to distinguish missing scope from a genuine saving. List owner-supplied equipment explicitly so the interfaces do not disappear between contracts.

Change the questions if you will lease it out

An investment buyer should test the range of plausible occupiers and their adaptation burden. A highly specific layout may work for the existing user while limiting replacement demand. Consider void periods, maintenance and building expenditure rather than applying a rental figure to the purchase price in isolation.

If a group company will own the property, examine corporate acquisition structure alongside the physical assessment. Decide who funds landlord works and how future occupier requirements would be evaluated.

Put the unanswered questions into the negotiation

Before making a binding commitment, give the legal adviser a concise list of missing records, essential works and unresolved approvals or rights. Agree how those matters will be addressed and what the handover must include.

A residential plan needs a dedicated commercial-to-residential conversion assessment. If the premises will house a business, establish the applicable activity-permit or declaration procedure and the conditions for opening.

To begin a focused search, share your commercial premises brief: location, intended activity, essential area, total investment range and desired opening date. Those details help distinguish a workable business location from a unit that is merely available.
