Design, Cost & Planning
BuildTech takes on a limited number of new home projects in Dublin each year. Every new home project begins with a feasibility consultation to establish the full build cost — before any design work is commissioned. We do not progress any project without a clear, agreed budget.

New home construction is the most complex and cost-variable category of residential building work. Site conditions, foundation requirements, structural design, and specification all have a significant impact on the final cost — and most of these variables are not known until a proper site assessment is carried out.
BuildTech’s feasibility-first approach means we establish the full build cost — based on a proper site assessment, planning analysis, and specification discussion — before any design work is commissioned. You know what your new home will cost before you commit to anything.

BuildTech manages the full new home project in-house — from the feasibility assessment and architectural design through to planning application, structural engineering, construction, and handover. No third-party handoffs, no delays between stages.
Every new home is managed with a clear, agreed cost, managed by a dedicated project manager, and certified by an independent chartered engineer on completion. The completed home is fully compliant with Irish Building Regulations and ready for mortgage drawdown.
BuildTech follows a clear four-step pathway, from initial feasibility through to completed construction, designed to protect your budget and keep your project on track.
BuildTech takes on a limited number of new home projects each year — ensuring every project receives the full attention and expertise of our design and build team. We do not progress any new home project without a clear, agreed budget and a comprehensive feasibility assessment.
Our minimum project value for new homes is €250,000. If your project is below this threshold, or if the site assessment indicates a project is not viable, we will tell you clearly and honestly at the outset.
BuildTech manages the full planning permission process from initial feasibility through to decision. Every stage is handled internally — there are no third-party handoffs that cause delays or miscommunication.
We confirm whether your project requires planning permission or qualifies as Exempted Development. Many single-storey rear extensions in Dublin do not need planning — we establish this clearly at the outset, saving you time and fees.
Where planning is required, we develop a pre-planning strategy aligned with the relevant local authority's development policies. Where appropriate, we engage with the planning authority informally before submission to identify potential issues early and reduce the risk of refusal.
Our in-house architectural design team prepares all required drawings — site location map, site plan, floor plans, elevations, and sections — along with any supporting reports and compliance documentation. Accurate, complete documentation reduces the risk of requests for further information from the council.
We prepare and submit the full application to the relevant local authority — Dublin City Council, Dún Laoghaire-Rathdown, Fingal, or South Dublin County Council. We manage all correspondence and respond to any requests for further information within the statutory timeframes.
We monitor the application through to decision — typically 8–12 weeks from submission. On receipt of planning permission, we advise on any conditions attached and prepare the project for the next stage: cost and technical design, or construction if design is already complete.
Delays and refusals in planning applications are almost always avoidable with proper preparation. The most common causes in Dublin are:
Missing drawings, incorrect scale, or absent site information trigger requests for further information — adding weeks to the process.
Designs that don't align with the local development plan — on height, scale, overlooking, or amenity — attract objections or conditions.
Submitting without checking with the planning authority first misses an opportunity to identify issues before they become formal refusal reasons.
Applying for full permission when the works are Exempted Development — or vice versa — wastes time & money. We confirm the correct route at feasibility stage.
Many home extensions and improvements in Dublin qualify as Exempted Development under the Planning and Development Regulations — meaning no planning application is required. However, exemptions are subject to specific conditions and can be lost if previous unauthorised works exist on the property.
Common Exempted Development for residential properties includes:
BuildTech confirms planning status as part of every feasibility consultation — before any design fees are committed. If your project is Exempted Development, we will tell you clearly and save you the cost of an application.
