Are you planning to redesign a garden in Cascais, transform a sloped plot in Sintra, or finally put the finishing touches on a newly built home? One of the first questions property owners ask is: How much does landscaping cost in Portugal in 2026? There is no single fixed price, but as an initial planning reference, landscaping projects in 2026 commonly fall within a range of approximately €30 to €300 or more per square metre, depending on the scope of work, the materials chosen, and the condition of the site.
These figures should only be used as an early reference. A reliable budget requires a site visit, a clear design brief, and an itemised quotation.
Indicative Landscaping Costs per Square Metre
The cost per square metre varies significantly according to the level of intervention.
Basic Landscaping
Soil levelling, natural lawn or simple planting, basic irrigation, and minimal hard surfaces typically cost approximately €30 to €70 per square metre.
This level suits gardens that are already reasonably flat and only need a fresh, functional finish.
Mid-Range Landscaping
A more complete garden with a planting design, automatic irrigation, defined paths or a small terrace, and garden lighting typically costs approximately €70 to €150 per square metre.
This is the most common range for family homes in Cascais, Estoril, and São Domingos de Rana.
Premium Landscaping
High-end projects with natural stone terraces, retaining walls, mature trees, integrated lighting, outdoor kitchens, or water features typically cost approximately €150 to €300 per square metre, and more for complex hillside gardens or architect-designed spaces.
Example Budget for a 300 m² Garden
For a garden of approximately 300 square metres, the basic estimate could look like this:
Basic landscaping at €30–€70/m²: approximately €9,000 to €21,000;
Mid-range landscaping at €70–€150/m²: approximately €21,000 to €45,000;
Premium landscaping at €150–€300/m²: approximately €45,000 to €90,000.
These examples do not automatically include earthworks on sloped land, retaining walls, swimming pools, or outdoor structures. For this reason, multiplying the garden area by a standard rate is useful for initial planning but is not sufficient for establishing the final investment.
What Are the Primary Factors Influencing Landscaping Costs?
The total cost of a landscaping project depends on the condition of the site and the ambition of the design. A flat, cleared plot with good soil is very different from a sloped hillside covered in rock and overgrown vegetation, which is common in parts of Sintra. In our experience at MS Atlantida, the ground preparation often determines the final budget more than the plants themselves.
The slope and topography of the plot;
Soil quality and the need for soil replacement or improvement;
Accessibility for machinery and material delivery;
Choice of paving, stone, and plant species;
Irrigation and drainage requirements;
Lighting and any outdoor structures.
How Does Site Preparation Affect the Budget?
Site preparation is the least visible part of a landscaping project and often the most important. Clearing vegetation, removing debris, levelling the ground, and improving poor soil must be completed before any planting or paving begins. On difficult sites, site preparation can represent 15% to 30% of the total project cost.
Rocky terrain, overgrown plots, and properties with old foundations or buried debris require heavier machinery and more time. Properties with narrow gates or steep access, common in Sintra, may also require smaller equipment or manual work, adding 10% to 20% to the overall project.
How Much Does Garden Irrigation Cost?
An automatic irrigation system is one of the most cost-effective investments in a Portuguese garden, given the long, dry summers. A typical residential system, with zones, controller, and drip lines for planting beds, usually costs between €1,500 and €5,000, depending on garden size and complexity.
Installing irrigation during construction is significantly cheaper than adding it later, when lawns, paving, and planting are already in place and must be cut open.
How Much Do Lawns, Paving, and Planting Cost?
Each element of the garden has its own price range:
Natural lawn, installed: approximately €8 to €20 per square metre;
Artificial turf, installed: approximately €25 to €50 per square metre;
Paving and stonework (calçada portuguesa, stone, porcelain): approximately €80 to €200 per square metre;
Retaining walls: approximately €150 to €350 per linear metre;
Mature olive trees and specimen trees: from a few hundred euros to well over €2,000 each;
Garden lighting: approximately €1,000 to €4,000 for a typical residential garden.
Choosing climate-appropriate native and Mediterranean plants, such as lavender, rosemary, olive, and cork oak, also reduces long-term water use and maintenance costs.
Why Do Slopes and Hillside Gardens Cost More?
Sloped gardens require terracing, retaining walls, and proper drainage to prevent erosion and water damage. In Sintra, where gardens are often built on steep ground, these structural elements can add 15% to 30% to the base landscaping cost. They are also not optional: cutting corners on retaining walls or drainage on a slope almost always leads to costly repairs within a few years.
Costs That May Not Be Included in the Landscaping Price
A common budgeting mistake is assuming that the quotation covers the complete outdoor project. Depending on the contractor, the following items may be separate:
Design or architectural fees for the garden;
Earthworks, excavation, and waste removal;
Retaining walls and drainage systems;
Municipal licensing, where required;
Swimming pools, pergolas, and outdoor kitchens;
Electrical connections for lighting and irrigation controllers;
Ongoing maintenance and gardening services.
Every quotation should clearly state what is included, excluded, provisional, or subject to later measurement.
Common Mistakes When Budgeting for Landscaping
Choosing plants before checking soil, sun exposure, and water availability;
Installing irrigation after the lawn and paving instead of before;
Ignoring drainage, especially on slopes and near the house;
Selecting cheap paving that fades, cracks, or becomes slippery;
Not reserving a contingency budget of approximately 10% to 15%;
Comparing quotations that do not cover the same scope of work.

Frequently Asked Questions
How much does landscaping cost in Portugal in 2026?
Landscaping commonly ranges from approximately €30 per square metre for basic work to €300 per square metre or more for premium projects, depending on the scope, materials, and site conditions.
How long does a landscaping project take?
A small to mid-sized garden typically takes between two and six weeks, while larger or hillside projects with retaining walls and drainage can take several months.
Do I need a permit for landscaping work?
Simple planting and garden works generally do not, but retaining walls, significant earthworks, and structures such as pergolas or pools may require municipal approval.
Is automatic irrigation worth it?
Yes. Given the dry Portuguese summers, automatic irrigation protects your planting investment and reduces water waste compared with manual watering.
Which is cheaper: natural lawn or artificial turf?
Natural lawn is cheaper to install, but requires water and regular maintenance. Artificial turf costs more upfront and needs less upkeep, though it does not provide the same cooling and ecological benefits.
Does the quotation include VAT?
Not always. Quotations should clearly state whether VAT is included and which tax treatment applies.
