Every Design We Produce Is Aligned With Your Build Cost

The traditional design process in Dublin produces drawings that look great but cannot be built within the client’s budget. By the time the design is finished and contractor quotes come in, the budget has already been exceeded — and the drawings need to be redesigned.

BuildTech’s cost and technical design service keeps the budget and the design in step at every stage. We carry out a detailed measured survey, produce technical drawings, and cost the design as we go — so the finished drawing set always reflects what can actually be built within your budget.

  • Measured survey — accurate as-existing drawings of your property produced at the outset
  • Budget-led design — costs tracked at every stage, not revealed at the end
  • Technical drawings produced to construction standard — ready for planning and building

Full Project Management

A Detailed Cost Plan Before Any Construction Is Committed

At the end of the cost and technical design stage, you receive a detailed, line-by-line fixed-price cost plan — covering every element of the construction from groundworks to finishes. This is the basis for the construction contract. There are no open tenders, no hidden costs, and no surprises.

If the cost plan aligns with your budget, the construction contract is prepared and works can begin. If any element exceeds expectations, it is addressed at this stage — before a single brick has been laid.

  • Line-by-line fixed-price cost plan — every element of the construction costed in detail
  • No open tenders — BuildTech provides a direct fixed-price contract based on the technical drawings
  • Budget review at this stage — any adjustments made before construction begins

Not sure what your home renovation will cost? We give you full cost clarity before you commit to anything.

Why BuildTech

Why Choose BuildTech for Cost & Technical Design?

BuildTech is a design and build contractor — not a standalone architectural practice. We produce technical drawings because we build the projects ourselves. Every drawing we produce reflects what the build will actually cost — because we price it directly.

We do not produce designs that cannot be built within your budget. If your expectations and your budget do not align, we will tell you at the feasibility stage — before any design fees are committed.

  • We do not progress projects without a clear, agreed budget — always
  • Design and build contractor — our drawings reflect real construction costs, not estimates
  • Budget tracked at every stage of the design — no surprises when the cost plan is produced
  • All works certified by an Independent Chartered Engineer on completion
How It Works

Our Planning Application Process

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.

Feasibility & Exemption Check

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.

Pre-Planning Strategy & Local Authority Engagement

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.

Planning Drawings & Documentation

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.

Submission & Application Management

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.

Decision Monitoring & Next Steps

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.

Common Issues

What Can Cause Delays or Refusals in Planning Applications?

Delays and refusals in planning applications are almost always avoidable with proper preparation. The most common causes in Dublin are:

Incomplete documentation

Missing drawings, incorrect scale, or absent site information trigger requests for further information — adding weeks to the process.

Policy conflicts

Designs that don't align with the local development plan — on height, scale, overlooking, or amenity — attract objections or conditions.

No pre-planning engagement

Submitting without checking with the planning authority first misses an opportunity to identify issues before they become formal refusal reasons.

Wrong application type

Applying for full permission when the works are Exempted Development — or vice versa — wastes time & money. We confirm the correct route at feasibility stage.

Exempted Development

What Can You Build Without Planning Permission in Dublin?

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:

Not sure if your project needs planning?

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.

Common Questions

Frequently Asked Questions

The cost and technical design stage includes: a measured survey of the existing property; as-existing drawings; proposed design drawings (floor plans, elevations, sections); technical drawings to construction standard; a planning application (where required); a detailed fixed-price cost plan covering every element of the build; and preparation of the construction contract.
The fee depends on the scope and complexity of the project. BuildTech confirms the design fee at the feasibility consultation stage — before any design work is commissioned. The design fee is then fixed for the full design process.
Not for most projects. BuildTech coordinates structural engineering requirements as part of the design process, engaging a structural engineer directly where needed. For projects that require engineer certification on completion — as most BuildTech projects do — this is arranged as part of the overall project.
Yes — the technical drawings belong to you. However, the fixed-price cost plan is based on BuildTech building the project. If you take the drawings to another contractor, you will need to obtain separate quotes.
For a typical single-storey rear extension, the cost and technical design stage typically takes 4–8 weeks from survey to completed drawing set and cost plan. More complex projects take longer. BuildTech will confirm the programme at the outset.
