Project statement

RUA 07 is a speculative urban residential study for a compact infill site in Porto. The proposal places five apartments within a quiet four-storey limestone building, using recessed loggias, a planted lightwell and a set-back roof terrace to make a dense city plot feel generous.

The architecture is deliberately calm: pale honed limestone, warm oak, off-white plaster and fine dark-bronze frames. Shared circulation is daylit and legible, while each residence has a private outdoor threshold and a clear relationship to the street or lightwell.

The building explores how a small urban block can provide privacy, daylight, outdoor space and practical services without resorting to a resort language. All areas and costs are illustrative design-stage assumptions.

Reading the project

The shared stair and lightwell give five homes a clear common address without dissolving their privacy. Recessed loggias act as small outdoor rooms, mediating between the city and each interior. Service and circulation space is treated as part of residential quality, rather than residual floor area.

A restrained set of surfaces connects the spaces throughout this concept. The image detail shows their intended relationship; finishes remain illustrative rather than product specifications.

Conceptual budget / 2026

Estimated construction budget: €2.6M–€3.8M
Estimated total development cost: €5M–€7.5M+

These are illustrative design-stage budget scenarios for fictional projects, not contractor quotes, valuations, researched market prices or offers for sale. Acquisition allowances are invented planning assumptions, not valuations of land or buildings. Actual costs may fall outside these ranges.

Budget assumptions

Allowance	Concept range
Construction & fit-out	€2.6M–€3.8M
Illustrative site acquisition allowance	€1.2M–€2M
Fees, taxes, enabling works & contingency allowance	€1.2M–€1.7M

Acquisition and the listed allowances are included in the total scenario. Financing is excluded. Planning requirements, professional fees, engineering, permits, taxes, infrastructure and site-specific conditions may materially change the result; these allowances have not been independently assessed.

The roof terrace is set back behind a low parapet to reduce its presence from the street.
No real parcel, planning permission, building approval or development right is represented.

Concept status & limitations

RUA 07 is a conceptual and unbuilt design study. Images, plans, dimensions, materials, costs and architectural details are illustrative and may be AI-assisted.

The project is not intended for construction, permitting, structural design, engineering, code compliance, valuation or professional architectural services. Any real-world version would require a real site and review by appropriately qualified professionals and authorities.
