A Defining Choice for Your Project

Should you build new or renovate an existing property? This question comes up early in any housing project, and the answer is not always what you’d expect. Each option has its strengths and weaknesses. It all depends on your situation, budget and priorities.

NEW BUILD vs RENOVATION NEW BUILD RENOVATION COST €1,500 – €2,500/m² ✗ Higher €800 – €2,000/m² ✓ Often cheaper TIMELINE 12 to 18 months ✗ 6 to 15 months ✓ ENERGY STANDARDS RE2020 by default ✓ Variable, depends on fabric ✗ CUSTOMISATION Total ✓ Limited by existing structure ✗ LOCATION Depends on land supply ✗ Often town centres ✓ PLANNING PROCESS Full planning permission ● Permission or prior notice ✓ ✓ Advantage ✗ Disadvantage ● Neutral Indicative comparison — every project is unique

The Comparison Table

Criterion New build Renovation
Average cost per m² €1,500 – €2,500 €800 – €2,000 (highly variable)
Overall timeline 12 to 18 months 6 to 15 months (depends on scope)
Energy performance RE2020 standard, excellent Variable, depends on existing fabric
Customisation Total Limited by existing structure
Mid-project surprises Rare Frequent (hidden defects)
Location Depends on available land Often better located (town centres)
Planning process Full planning permission Permission or prior notification
Financial incentives Interest-free loan, tax relief Renovation grants, green loans
Warranties 10-year structural, completion 10-year on new works only
Environmental impact Land take (soil sealing) Reuse of existing buildings

Advantages of Building New

Everything Is Bespoke

With a new build, you start from a blank canvas. Room layout, orientation, materials, fittings: everything is chosen to match your needs.

Guaranteed Performance

New homes comply with RE2020, the most demanding thermal and environmental regulation. This means:

  • Very low energy bills
  • Thermal comfort in summer and winter
  • Better long-term resale value

Robust Warranties

New construction offers a protective legal framework:

  • Completion warranty (1 year)
  • Equipment warranty (2 years)
  • Structural warranty (10 years)
  • Building warranty insurance mandatory

💡 Tip — With a CCMI (Individual House Construction Contract), you also benefit from a guaranteed price and delivery date. It’s the most legally secure formula.

Advantages of Renovation

Often a Better Location

Building land is becoming scarce, especially in high-demand areas. Renovating an existing property lets you access town-centre locations or sought-after rural areas where land simply isn’t available.

Architectural Character

Exposed beams, stone walls, vintage floor tiles… Renovation preserves heritage and character that new builds simply cannot replicate.

An Environmental Choice

Renovating avoids soil sealing and reuses existing materials. In the context of land sobriety goals (zero net land take), this is a compelling argument.

⚠️ Warning — In renovation projects, nasty surprises are commonplace: rotten roof timbers, damp walls, outdated electrics, asbestos, lead paint. Always commission a full survey before purchasing.

When to Choose a New Build

  • You’ve found land in an area you like
  • You want a 100 % customised home
  • Energy performance is a top priority
  • You don’t want to deal with renovation uncertainties
  • Your budget covers land + construction

When to Choose Renovation

  • You’ve fallen in love with an existing property
  • The location is irreplaceable (town centre, views, near family)
  • You appreciate the character of older buildings
  • Your budget doesn’t stretch to land + new build
  • You want to take advantage of energy renovation grants

The Hybrid Option: Extension or Loft Conversion

There is a third way: buy an existing property and extend it (ground-floor extension, loft conversion, or adding a storey). This combines some advantages of both options:

  • Existing location + brand-new spaces
  • Renovated older sections + new sections built to current standards
  • Often a mid-range budget

💡 Tip — Before considering an extension, check the local plan and maximum building coverage for the plot. Some municipalities heavily restrict the footprint or maximum height. An architect can quickly tell you whether the project is feasible.

Checklist to Help You Decide

  • Total budget estimated (land + build or purchase + renovation)
  • Desired location identified and availability checked
  • Priorities ranked (customisation, location, character, performance)
  • Surveys completed if renovating (structure, energy, asbestos, lead)
  • Financial incentives simulated for each option
  • Acceptable timelines defined
  • Professionals consulted (architect, project manager, estate agent)

Key Takeaway

There is no universal answer. New build offers customisation, performance and warranties. Renovation offers location, character and reduced land take. Take the time to lay both scenarios side by side, figures in hand, before making your decision.
