Design, Cost & Planning

Feasibility Consultation Dublin: Get Real Costs Before You Pay for Drawings

Most extension projects go over budget for one reason. The design gets drawn before anyone works out what the build will actually cost. A feasibility consultation fixes that. You get a real budget, a planning check and honest advice first, so nothing is drawn on a hope.

Feasibility First

One Expert Consultation to Know Exactly Where You Stand

A feasibility consultation is an initial session where we work out what your extension or renovation can realistically cost and achieve, before you spend anything on design. You leave with a real budget range, a clear planning position, and honest advice on your options. Nothing is drawn until the numbers work.

It is the step most homeowners skip and later regret. An architect can draw you a beautiful house extension. What they rarely do is tell you, up front, whether it can be built for the money you have. We start there, whether you are planning an extension or a full home renovation, because a design you cannot afford to build is a design you pay for twice.

Full Project Management

If the Numbers Don't Work, You Hear It on Day One

If your budget and your plans do not line up, we tell you right away at the consultation. That honesty is the whole point. It is far easier to hear early, when you can still change the scope, the finish or the timing, than after the drawings are done and paid for.

If everything aligns with your budget, we move to our full project management where we do everything, including architectural design, application planning, and construction. Everything we do comes under a budget you agreed on.

  • We price against what materials and labour actually cost in Dublin right now
  • We flag the structural and planning issues that quietly push budgets up
  • We show you where a smaller change gets most of the result for less

Why BuildTech

Why Homeowners Trust BuildTech Feasibility Consultation

Homeowners come to us first because our price, cost & technical design and construction start once we both are both aligned on the final budget. With us, the price you pay always sits between the budget we discussed at our initial feasibility consultation.

It is a different starting point, and it protects your money. You are not paying for a design in the hope a builder can later make it fit the budget. You agree the budget with the builder first, then design to it. That is the whole idea behind feasibility-led costing.

  • Feasibility-led costing using real construction data, not rough estimates
  • A dedicated project manager as your single point of contact, start to finish
  • A client portal showing your drawings, costs and progress at any time
  • Every build certified on completion by an Independent Chartered Engineer
  • CIF member, CIRI registered and CIOB accredited, and fully insured
How It Works

What Actually Happens in Your Consultation

We talk budget and goals

You tell us what you want and what you can spend. We listen for the choices that will drive the cost, and the parts you care most about keeping.

We check your planning position

We tell you whether your project is likely exempt or needs a full application, so there are no surprises once the work is underway.

We price it with real Dublin costs

You get a realistic cost range for the work, based on projects we have actually delivered, not a figure pulled from an online calculator.

We show you what is achievable

If the budget and the plan do not match, we say so, and we show you the options that do: a smaller scope, phased work, or a different approach.

You leave with clear next steps

A written summary of what we discussed, the numbers, and what to do next. On an on-site visit, that includes a look at the structure and access. No obligation to go further.

Common Issues

Four Costly Mistakes This Consultation Saves You From

Most extension and renovation budgets blow up for reasons that are obvious in hindsight and avoidable at the start. A feasibility consultation catches all four before they cost you.

Paying for drawings you cannot build

Commissioning a full design before anyone confirms it fits your budget. The most common, and most expensive, mistake.

Designs priced past your budget

A detailed plan that comes back tens of thousands over, forcing a redesign you also pay for.

The wrong planning route

Applying for permission you did not need, or assuming an exemption you did not have. Both cost time and money.

Guesswork instead of real costs

Budgeting off a per-square-metre figure from a blog, then finding your site, access or spec changes everything.

How We Assess Whether Your Project Is Feasible

Feasibility is a common question people ask. Can this project be built, for this money, on this site, in a sensible timeframe? Here is what we assess to answer it properly.

Budget against scope: Whether what you want to build matches what you want to spend

Planning position: Whether your project is exempt or needs planning permission, and how likely it is to be granted

Structural reality: What the existing building and site will actually allow, and what that adds to the cost

A realistic timeline: How long the work will take, planning included if it is needed

Not sure if you need planning permission?

A single-storey rear extension is often exempt if it stays under 40m² of floor area and keeps your rear garden above 25m². We confirm it at your consultation.

Common Questions

Frequently Asked Questions

It is a paid session where BuildTech works out what your extension or renovation can realistically cost and achieve, before you spend anything on design. You get a real budget range, a planning check and honest advice on your options. It is the step that stops projects going over budget.
€200 for a phone or video consultation, or €500 for an on-site home visit. If you go ahead with your project, the fee is credited toward your design costs. Most homeowners find it saves them far more than that, by avoiding a design that cannot be built within budget.
Choose the €200 phone or video call if your project is straightforward and you mainly need budget and planning guidance. Choose the €500 on-site visit for anything involving structural changes, awkward access or an older property, where seeing the building in person changes the advice.
BuildTech takes on extensions and whole-home renovations with a minimum project value of €100,000. We are a specialist design and build contractor, not a general builder, so we do not take on single-trade or cosmetic-only jobs. The consultation will tell you honestly if we are the right fit.
Often, no. Many single-storey rear extensions are exempt if they stay under 40m² of floor area and keep your rear garden above 25m². Your exact position depends on your site and any previous extensions, and we confirm it at your consultation.
