Design, Cost & Planning

New Home Builders in Dublin Who Cost Your Build Before You Buy the Site

Building your own home is the biggest project most people ever take on, and the cost is the hardest part to pin down. BuildTech settles that first. As new home builders in Dublin, we confirm your full build cost before any design work begins, using the same feasibility-led model we use for extensions and renovations.

What Decides the Cost of Your One-off House in Dublin

The site decides most of your build cost, not the house you picture on it. Two identical designs can come in thousands apart, because the ground conditions and the access do the real damage to a budget. 

None of that shows up until someone assesses the site properly. So that is where we start. We confirm the full build cost from a site assessment and a specification review before any design work begins, so you commit to a real figure.

  • Full site assessment covering ground conditions, access, and services
  • Planning and zoning context reviewed before you spend on drawings
  • The full build cost confirmed and agreed before design begins

One Team from Site Assessment to Handover, with No Gaps to Fall Through

One-off builds might go wrong at the handovers. The architect passes to the engineer, the engineer passes to the builder, and somewhere in the gaps the budget and the timeline slip. BuildTech closes those gaps. 

We run the whole home renovation and extension project in-house, including the architectural design, the planning, the handover, and everything in between under one project manager. Every home is built to a fixed price agreed upon up front, certified by an Independent Chartered Engineer, and handed over ready for mortgage drawdown.

  • In-house architectural design suited to your site, brief, and budget
  • Planning application managed in full, from pre-planning to decision
  • Fixed-price construction contract agreed before work starts

Why BuildTech

Why Choose BuildTech as Your New Home Builders in Dublin

We would rather lose the job at the start than let you lose money. BuildTech takes on a small number of one-off homes each year, alongside our renovation and house extension service, so every project gets our full attention. 

We build for owner-occupiers who have a site in Dublin and want a fixed cost before they commit. If the site assessment says a project will not work, or your budget and your plans do not match, we say so on day one. 

  • Owner-occupiers building a one-off home on a site in Dublin
  • Clients who want a fixed cost agreed before design begins
  • Minimum project value €100,000, with honest advice if a site is not viable
  • Limited project numbers, so every home gets full attention

How We De-risk Full Planning Permission for Your New Home

Every new home in Ireland needs full planning permission. There is no shortcut and no exemption, so the application has to be right the first time. BuildTech handles all of it in-house, from the first site check to the final decision. 

Here is how the process runs.

Site feasibility and zoning check

Before we draw a line, we confirm the site can take a home. We check the zoning, the planning history, and the local development plan. If a site will not get permission, you find out now, not after you have paid for drawings.

Pre-planning consultation with the council

Where it helps, we talk to the council before we submit. A pre-planning meeting brings up concerns on height, scale, or overlooking early, so we design them out instead of getting refused for them.

Full planning drawings and reports

Our in-house design team prepares the full application: site maps, floor plans, elevations, sections, and any reports the council needs. Complete, accurate drawings keep the council from coming back with requests that add weeks.

Submission and application management

We submit to the right authority, Dublin City Council, Dún Laoghaire-Rathdown, Fingal, or South Dublin County Council, and handle every piece of correspondence. If they ask for more information, we respond inside the official timeframe.

Decision and conditions

We track the application to decision, usually 8 to 12 weeks after submission. When permission comes through, we explain any conditions attached and move the project into technical design and build.

Common Issues

Why New Home Planning Applications Get Refused in Dublin

Most refusals are avoidable. On new homes in Dublin, the same handful of problems come up again and again, and each one can be headed off with the right groundwork.

Site or zoning problems

A site that is not zoned for housing, or that has ground or access problems, may never support a home. We check this at feasibility, before any money goes into design.

Conflict with the development plan

Designs that ignore the local development plan draw objections and conditions. We design to the plan from the first sketch.

No pre-planning engagement

Skip the conversation with the council and you miss the chance to fix problems before they become refusals. We do not skip it.

Incomplete documentation

Missing drawings or the wrong scale trigger a request for more information, and that adds weeks. We submit complete applications.

Can You Build a Home on Your Site? How BuildTech Helps You

Not every site in Dublin can take a new home, and that is the first thing we settle. A site needs housing zoning, ground that will carry the build, workable access, and a way to connect water, drainage, and power. Planning history matters too. 

We assess all of it before any design work begins, so you know early whether a home is possible, how big it can be, and what it will cost. If the answer is no, we tell you before you spend a euro on drawings.

  • Residential zoning and planning history confirmed
  • Ground conditions, access, and services assessed
  • Achievable scale and full build cost established

Common Questions

Frequently Asked Questions

Our minimum project value is €100,000. A new build in Dublin will usually sit well above that, given the design, planning, and structural work involved. If your project falls below the minimum, we will tell you straight away.
It depends on the site, the size, and the specification. In 2026, building a new home in Dublin typically costs €2,500 to €4,000 per sqm, so a 150 sqm home usually lands between €375,000 and €600,000 to build. Site costs like purchase and connections are on top. We give you a project-specific cost plan at the feasibility stage.
Yes. Every new home in Ireland needs full planning permission, and a decision usually takes 8 to 12 weeks from submission. There is no exemption for a new house. We manage the full application for you.
A home of 150 to 200 sqm usually takes 12 to 20 months from planning permission to handover, covering design, planning, and construction. You get a detailed programme at the technical design stage.
A one-off house is a home built on its own site, rather than a unit in an estate. Yes, one-off homes are exactly what we build, on sites right across Dublin, through our feasibility-led design and build model.
