Diagonal Mar and the Front Marítim: homes by the coast

Diagonal Mar i el Front Marítim del Poblenou · Sant Martí · Barcelona

Neighbourhood history

The neighbourhood combines the original Diagonal Mar development with projects built from the late 1990s. Enric Miralles’s park and the residential blocks of the Front Marítim transformed the area. Surviving industrial spaces preserve part of its earlier urban history.

Historical context: source consulted

What to check when valuing a home

Floor level, actual views, aspect and terraces can strongly affect comparisons here. Separate internal from outdoor space and check whether parking, storage or shared facilities are included. Review service charges and avoid applying one average indiscriminately to every tower.

05 · Sources and methodology

What these
figures tell us

A useful comparison starts with understanding what each figure measures. Open the historical tables and read the notes accompanying each indicator.

Are these asking prices or recorded sale prices?

The market section uses averages from recorded transactions, based on notarial statistics published by the City Council. These differ from the asking prices shown on property portals.

Why do the reference dates differ?

Sales, cadastral, population register and income data are released on different schedules. Each section shows its reference period. Viewing this page today does not mean all indicators relate to the same year.

Does the average floor area cover all homes?

The sales section measures the homes that were sold. The housing stock section measures homes recorded in the cadastre. These are different populations, so their averages can differ.

What do “Suppressed” and “Not published” mean?

“Suppressed” means the source withholds the information to protect confidentiality. “Not published” means no value is available for the category and period shown. Neither expression means zero.

Can I value my home using the price per m²?

The neighbourhood average is a general reference. An individual valuation requires an assessment of the exact location, floor area, floor level, lift, natural light, condition and building characteristics, together with suitable comparable properties.
