Weevir · Extension Readiness Report
Know what your extension needs — and what costs to expect — before you start.
One report on your property. Planning, site constraints, a realistic cost band and the questions to ask a builder. €149. Delivered in 5 working days.
What you get
Six things you’ll know by the end of the week.
Extensions rarely come unstuck on site. They come unstuck in the quiet decisions made months earlier — an assumption about exemption that turns out not to hold, a condition on the address nobody thought to look for, a quote accepted with nothing to measure it against. By the time those surface, they’re expensive. This puts them in front of you first.
-
Where you stand on planning
Whether what you have in mind sits inside the exemptions, or needs an application — and what that means for your timeline.
-
What your site brings with it
The designations and constraints attached to your address — the ones that tend to surface late, when they cost the most to work around.
-
What’s already been decided nearby
How your council has treated extensions like yours on your road, and the conditions they attached when they said yes.
-
What it should cost
An indicative range for your type of build in your region, so you can tell a fair quote from an optimistic one. Not a quote itself.
-
What compliance actually asks of you
The Building Regulations obligations, certification and notices your extension has to satisfy — in plain English, before a builder starts rather than after.
-
How to hold a builder to it
What to ask, what to insist on seeing in writing, and how to structure payment so you keep the upper hand.
And when you’re ready to move
Most home extensions don’t call for a full architectural design. What they call for is a proper set of plans and a build that stands up to the Building Regulations — which is a smaller, cheaper piece of work than people are usually sold.
If you’d like that handled, our chartered planner can pick it up from the report: the plans, the drawings and the compliance paperwork, on a property we’ve already assessed. No obligation either way — plenty of people take the report and run with it themselves, and that’s a perfectly good outcome.
Who it’s for
You’re extending the house you live in.
You’re extending or renovating the house you live in. You don’t need a full architectural redesign — you need to know what’s required, what’s fair, and what to ask. This report gets you there before you pay for drawings or sign anything.
What it isn’t
It’s not a set of drawings, a quotation or a bank certification. Where your build needs those, the report tells you exactly what level of work is required and what it typically costs — and we can take it on from there if you’d like us to.
Who’s behind it
Reviewed and signed off by a chartered planner.
Every report is reviewed and signed off by a chartered planning consultant (MIPI) and registered building surveyor with over 25 years in Irish planning. The data engine is built by Weevir, an Irish planning-intelligence platform.

FAQ
Questions people ask.
Do I need planning permission for an extension?
Some rear extensions are exempt under the Planning and Development Regulations, subject to size, height and cumulative-area conditions. Many aren’t. The report gives you a verdict for your specific property.
Is the cost band a quote?
No. It’s an indicative range built from published Irish construction cost data and stated as a band with its sources and date. Use it to judge whether the quotes you get are in the right territory.
Can you do the drawings?
Yes — though often less than you’d expect. Many extensions don’t need a full architectural package, just a proper set of plans that satisfies the Building Regulations. The report tells you which your job needs, and our chartered planner can prepare it from there. You’re under no obligation to use us for it.
Where in Ireland do you cover?
Anywhere in the Republic of Ireland.
