How We Work — New Builds & Extensions

At EverBuild Property Services, we believe that every successful build starts with trust, planning, and clear communication.
Whether it’s a brand-new home or a beautifully crafted extension, our process is built around transparency, precision, and professionalism — from the very first consultation to the day we hand over the keys.

Here’s how we bring your vision to life.


1️⃣ Initial Consultation & Site Visit

Every great project starts with a conversation.
We take the time to understand your goals, budget, and timeline before offering expert advice tailored to your site and requirements.

During this stage, we will:

  • Discuss your design ideas, space needs, and lifestyle goals.

  • Review site photos, surveys, or drawings (if available).

  • Identify any potential planning or structural considerations.

  • Provide a clear outline of what’s possible within your budget.

We then arrange a site visit to assess the location, access, and conditions — ensuring our recommendations are practical, compliant, and cost-efficient.


2️⃣ Design & Planning Stage

Once we understand your vision, our team collaborates with experienced architects, engineers, and design partners to develop professional plans.

During this phase, we will:

  • Prepare design drawings and floor layouts.

  • Handle planning permission submissions (if required).

  • Ensure full Building Regulations and BC(A)R compliance.

  • Incorporate modern energy-efficient solutions such as insulation, glazing, and heat pumps.

  • Help you visualise the final build with detailed 3D renderings (optional).

Our goal is to ensure your design not only looks beautiful but also functions perfectly and meets all Irish building standards.


3️⃣ Transparent Quotation & Agreement

We pride ourselves on honest, itemised pricing.
Once designs are finalised, we provide a detailed written quotation outlining all costs — including materials, labour, and timelines — so there are no hidden surprises.

You’ll receive:

  • A comprehensive project quote broken down by stage.

  • Clear start and completion dates.

  • Payment schedule linked to milestone achievements.

  • Options for material upgrades or alternative finishes.

Once approved, both parties sign a project agreement, ensuring full transparency and accountability throughout.


4️⃣ Pre-Construction Preparation

Before we begin, we make sure every detail is ready:

  • Confirm planning approval and BC(A)R documentation.

  • Arrange all required insurance and site safety plans.

  • Schedule materials and trades to ensure an efficient workflow.

  • Communicate your project timeline clearly, including any expected disruptions.

Our preparation ensures a smooth, organised build from day one.


5️⃣ Construction Phase

Now the exciting part begins — watching your home come to life.
Our skilled tradesmen, engineers, and project managers work seamlessly to deliver high-quality workmanship while keeping you informed every step of the way.

What you can expect:

  • Professional on-site management by our foreman.

  • Regular progress updates and photos.

  • Coordination with certifiers and inspectors.

  • Strict adherence to safety, quality, and environmental standards.

  • Efficient problem-solving if unexpected site conditions arise.

We work respectfully in and around your property, minimising disruption wherever possible.


6️⃣ Quality Control & Inspections

EverBuild’s commitment to excellence means we inspect every stage of construction.
We work closely with your assigned certifier or engineer to ensure the build meets all Irish building regulations, including structure, insulation, and fire safety.

  • Internal quality checks are carried out daily.

  • External inspections are scheduled at key milestones.

  • All materials and workmanship are verified against specifications.

This level of oversight guarantees your home or extension is built safely, correctly, and to the highest standards.


7️⃣ Finishing Touches & Interior Fit-Out

Once the main structure is complete, our finishing team steps in to perfect the details.
From smooth plasterwork and custom carpentry to painting, flooring, and kitchen installations — every surface is finished to an immaculate standard.

We can also assist with:

  • Kitchen design and installation.

  • Bathroom fit-outs and tiling.

  • Electrical and lighting layouts.

  • Interior design coordination (optional).

Your new home or extension is cleaned, polished, and presented ready for move-in.


8️⃣ Final Handover & Certification

Before handover, we complete a comprehensive snag list inspection to ensure every element is finished to perfection.

You will receive:

  • BC(A)R Completion Certificate (where applicable).

  • BER Certificate (energy rating).

  • Warranty information for materials and installations.

  • Guidance on maintenance and aftercare.

Only when you are 100% satisfied do we consider the project complete.


9️⃣ Aftercare & Ongoing Support

Our relationship doesn’t end when the keys are handed over.
We stand by our work and offer ongoing support for any queries, maintenance, or additional improvements you may need in the future.

Many of our clients return to us years later for additional projects — a testament to the trust and satisfaction we build along the way.
