Renovating a home in Cascais is one of the most rewarding investments you can make. Understanding costs upfront saves you from surprises. Prices here tend to run slightly higher than inland Lisbon due to the premium local market and quality expectations of international residents.
Average Cost Ranges in 2026
For a full residential renovation in Cascais, expect to budget 400–900 EUR per m2 depending on scope, materials, and complexity.
Light Refresh (painting, flooring, fixtures): 150–300 EUR/m2
Mid-Range Renovation: 350–600 EUR/m2 — includes updated kitchens, bathrooms, new electrical and plumbing runs.
High-End Full Renovation: 650–1,200 EUR/m2 — custom finishes, premium materials, architectural changes.
What Drives Costs Up?
Building age is a major factor. Older buildings in the Cascais historic centre often require more structural work, waterproofing, or specialist surveys. Condo restrictions can also add time and cost — board approval is required in many buildings, with rules on working hours and materials delivery.
Narrow streets in Cascais can complicate logistics, and premium materials like custom joinery and engineered stone often carry 8–16 week lead times in 2026.
Kitchen and Bathroom Costs
A full kitchen renovation in Cascais runs from 8,000 EUR for a modest fit-out to 35,000 EUR or more for a bespoke design with high-end appliances. Bathrooms range from 4,500 EUR for a functional refresh to 20,000 EUR or more for a spa-quality result.
How to Control Your Budget
Get three quotes and be wary of the lowest one without explanation. Set aside 10–15% contingency, especially in older buildings. Specify everything in writing — materials, brands, finishes, and labour timeline. Reputable contractors do not ask for more than 30% upfront.
