Construir em Cascais: perguntas frequentes

Posso construir em terreno rústico em Cascais?

Cerca de 26% das parcelas classificadas na carta de uso do solo (CRUS) de Cascais estão em Solo Rústico. Em regra geral, o PDM restringe a edificação em solo rústico; a viabilidade depende da categoria de solo e das condicionantes aplicáveis. A resposta definitiva depende sempre da parcela concreta e do regulamento em vigor.

Que condicionantes afetam mais terrenos em Cascais?

Nos dados do Yonder para Cascais, as condicionantes com mais parcelas abrangidas são: Rede Natura 2000 (1995 parcelas), Reserva Agrícola Nacional (RAN) (1357 parcelas) e Domínio hídrico e margens (1296 parcelas). Os números referem-se apenas às parcelas já avaliadas por camada.

O que diz o PDM

Classificação da áreaMunicipality is zoned by multiple “space” categories with differing land-use regimes, including: Tourist Occupation Space (Level 1/Level 2), Equipment Space, Economic Activity Space (incl. subregimes), Energy and Geological Resources Space, Rural Agglomerations (incl. consolidated tourist-rural spaces with subcategories), Green Spaces for Protection/Conservation (and Green Space for Infrastructure Protection), Natural Space / Forest Space / Agricultural Space (incl. Level 1/2/3 natural/forest sublevels), and Natural/Environmental protection coastal/heliport/aeronautical protection zones and associated coastal strip regimes (Faixas de Proteção Costeira / Coastline Safeguard).
Dimensão típica dos lotesMinimum lot area: 300 m² (for the common building regime referenced).
Limite geral de alturaMaximum facade height varies by space/regime: 11.00 m (common urban building regime), up to 20.00 m (specific regime cited for Article 79), and 15.00 m (equipment-space regime cited). Max number of floors observed: up to 7 floors.
Estilo de construçãoNo municipality-wide single architectural style requirement stated; however, heritage conservation conventions must be observed for conservation/restoration works (e.g., Florence Charter) and there are special regimes conditioning interventions (historical farms/tourism, conservation areas, coastal protection).
Pontos-chave
  • Density and form controls are expressed through indices that vary by zone: FAR (0.50–1.00), IO (0.30–0.60), impermeability typically up to 0.60 (may reach 0.80 in some cases), plus setbacks (front 3.00 m; rear 6.00 m; sides 3.00 m) and max gable dimension/projection (18.00 m).
  • Minimum permeability requirements apply depending on lot size: 15% (≤300 m²) and 25% (>300–≤600 m²) for spaces with specific permeability rules.
  • Historical farms (quintas históricas) have conditioned expansion rules: allowed enlargement up to 20% (where applicable), with specific tourist-related regimes (Tourist Occupation Space Level 2).
  • Coastal strip rules allow permitted actions subject to authorization/conditions; demolition/reconstruction permitted without increasing height, and coastal protection constraints apply (Coastal Protection Strips / Safeguard / margins).
  • Major risk/environment constraints: susceptibility mapping (floods, fires, earthquakes, etc.) conditions works; prior opinion from Municipal Civil Protection Service required for developments in high/very high or moderate-to-high susceptibility areas; PNSC interventions require ICNF opinion/ministerial order with favorable opinion.
Planos futuros
  • Multiple approvals/controls tied to environmental and protection regimes (PNSC, coastal strip safeguard, aeronautical protection zones) including specific opinions/authorizations.
  • Regime emphasis on limited expansion and conditioned construction in higher-protection/natural categories (e.g., Natural Space Level 2/3 with low indices and expansion caps).
  • Urbanization/detail plans to promote soft mobility modes and connections with mobility/socio-urban networks (planning guidance, not parcel-specific).
NotasGeneral municipality-wide dimensional/land-use rules are governed by multiple “space” regimes (tourism, equipment, economic activity, energy/geology, natural/agricultural/forest, protection/green areas, coastal and aeronautical protection zones). Parking requirements are generally regulated through indicators (e.g., 1 space per 100 m² floor area; specific classroom-based rules for education uses) and municipal parking regulation applies until specific regulation enters into force.

Key building parameters found: - permitted use / allowed works: conservation works of existing and legal buildings - maximum extension / amplification of existing legal buildings: 20% - minimum distance to supporting infrastructure (existing legal buildings, for licensing): 50,00m - minimum commitment period for executing missing infrastructure: 10 years Article 51 (Characterization and Regime): The subcategory of forest space level 2 covers areas defined by COS 2018 and the proposed PG-ZEC as forest, exotic forests, native conifer forests, and scrub/brush areas, with predominantly recreation and landscape enhancement functions. Activities in this subcategory must align with the objectives and action lines of the PROF LVT for the recreation and landscape-enhancement function of forest spaces. Only works for the conservation of existing legal buildings are allowed. - permitted use / allowed works: conservation works of existing and legal buildings Article 51 (Characterization and Identification): The forest space category corresponds to areas with greater potential for forestry activity, in a sustainable way and compatible with functions of protection, habitat conservation, fauna and flora species, geosites, recreation, and landscape enhancement. Forest spaces are divided into forest space level 1 and forest space level 2. Article 44 (General Principles): Rural land must be preserved as a structuring part of the territory. Rural land has no inherent building vocation, so only the urban operations expressly allowed by the regulation or by specific legal regimes are admissible. In rural land, lotting, subdivision, and new buildings are generally prohibited, with exceptions for agricultural works, public infrastructure and equipment, reconstruction/alteration/amplification of existing legal buildings up to 20% of the existing floor area, and other listed cases. For existing legal buildings, the minimum supporting infrastructure distance is 50,00m, unless the applicant undertakes to execute the missing infrastructure for 10 years. - maximum extension / amplification of existing legal buildings: 20% - minimum distance to supporting infrastructure (existing legal buildings, for licensing): 50,00m - minimum commitment period for executing missing infrastructure: 10 years
