The same 2D plan can cost nothing, three hundred euros, or almost four thousand, depending on who produces it and how. It’s not a negotiation issue: these are three different markets, with three levels of accuracy and three cost structures, each addressing a specific need.
Before requesting a quote or downloading software, it’s better to understand which of these three approaches matches your volume of mandates. It is this often-overlooked calculation that explains why some agencies pay per property while others no longer bother.
What you will learn from this guide:
- What truly causes the price variation between different 2D plans
- The real cost of an on-site service, from a standardized plan to an architect’s survey
- The hidden expense of free software: the unbilled time nobody pays for
- How a subscription with an included plan changes the calculation after just a few mandates
- The volume threshold at which each method becomes most cost-effective
The level of detail visible on the plan — named rooms, surface areas, openings — directly impacts its price, regardless of the production method
What Influences the Cost of an Estate 2D Plan
A quote for a 2D plan is never a fixed price: it combines several variables, and two properties of the same size can be charged very differently depending on what is actually ordered.
Surface Area and Number of Rooms
With an external service provider, the time spent on-site increases with the property’s size and number of levels. A studio can be surveyed in a few minutes; a multi-storey house with outbuildings requires several hours of measurement, often billed additionally beyond a certain size. This is the most intuitive variable, and the only one that has no impact when generating a plan via smartphone scan, where the marginal cost remains the same regardless of property size.
Format and Level of Detail Requested
A listing plan doesn’t need the same deliverables as a technical report. A simple 2D sketch with surface areas costs significantly less than a complete survey including sections, facades, and an DWG file usable by an architect. It’s this confusion — ordering a survey-level deliverable for marketing purposes — that artificially inflates many agencies’ budgets (Obat).
On-site Provider: The Cost of Customization
Bringing in a professional remains the go-to method for exceptional properties or projects requiring technical plans. Two levels of service coexist in the French market, and confusing them skews comparison.
| Service | Content | Price Range | Turnaround |
|---|---|---|---|
| Standardized plan ordered online | 2D only, based on photos or simplified survey, no visit | €350 to €1,000 | Few days |
| On-site architectural survey (surveyor) | Plans, sections, facades, DWG file | €890 to €3,750 excluding VAT | One to two weeks |
| 3D plan as an add-on | Volumetric modeling of the property | €500 to €2,500 extra | Variable depending on detail |
The first price fits a standard listing: it provides a clean plan without locking the seller into an additional appointment. The second is justified when the deliverable serves beyond marketing — inheritance, renovation projects, lot divisions — as its price refunds a precision level that a typical property sale does not require (Obat).
The Invisible Cost: The Second Visit
The real extra cost of a service provider is often not on the quote. It’s the scheduling of an appointment that fits the seller’s, your, and the provider’s calendars, usually about a week after the mandate is signed — precisely when the listing should already be complete online. In a market where 7 times more visits differentiate a well-presented listing from an ordinary one, each day of delay has a cost no invoice shows.
Free Drawing Software: Zero Euro but Not Zero Cost
Many 2D plan software — simple vector drawing tools or interior layout editors — are free or offered with generous trial versions. On paper, this is the cheapest option on the market.
In practice, the cost shifts elsewhere: manually measuring dimensions with a laser meter, entering room by room into the software, then back-and-forth adjustments for missed measurements. Count on one to three hours per property for an agent already familiar with the tool — more for first-time use. Over a portfolio of twenty mandates annually, this results in twenty to sixty hours of work that no one bills to the client, but that are unavailable for prospecting or visits.
When this option remains relevant
The calculus depends on the agency’s workflow. An agent producing two or three plans a year easily recoups this time: the learning curve cost is amortized over that first property avoided through a provider. An agent handling one property per week, however, turns that same time into accumulated weeks over the year — this is the tipping point that pushes most active agencies towards automation.
2D Plans Included in Agency Subscriptions
A third trend has emerged with all-in-one tools for real estate agencies: 2D plans are no longer a pay-per-property service but a module included in a monthly subscription that also covers photos or videos. Depending on the market offerings, this module is either billed as part of a monthly package — sometimes over €150 for all services — or charged on usage, with credit packs consumed per plan, typically delivered within 24 to 48 hours.
This approach changes the nature of the cost: it becomes predictable and independent of the number of properties, as long as the subscription is active. This is exactly the opposite of a one-off service provider, whose price mechanically increases with volume.
The Real Cost: What the Displayed Price Doesn't Show
Comparing unit prices masks what truly matters: for an agency, it’s not the cost of a single plan but the cost of a portfolio over the year.
| Annual volume | Provider at €500 / plan | Free software (agent time) | Subscription with included plan |
|---|---|---|---|
| 5 properties/year | €2,500 | ~10 hours of agent time | Cost of subscription, plan included |
| 20 properties/year | €10,000 | ~40 hours of agent time | Cost of subscription, unchanged |
| 50 properties/year | €25,000 | ~100 hours of agent time | Cost of subscription, unchanged |
At low volumes, a one-off provider or free software remain sensible options: the total cost stays manageable, and the agent’s time is absorbed without issue. Once volume increases, the provider’s curve becomes linear — each plan adding its full cost — while the subscription cost remains flat. The crossing point, usually between five and eight properties per month for an active agent, determines the most cost-effective method, much more than the isolated quote price.
How Much Does a 2D Plan Cost with IACrea
The plan delivered after scanning: same level of detail as previous examples, no negotiation of quotes property-by-property
On the platform, the 2D plan is one of the features included in the subscription: a five-minute scan during the visit with the IACrea real estate photo app, then an adjustment in the web editor, without separate order or per-property invoice. The marginal cost of an additional plan is therefore zero once the subscription is active — exactly the mechanism that favors volume, as described above. Our pricing details the packages and the number of properties covered per tier.
This low cost doesn’t change the nature of the deliverable: like any scan-based plan, it remains indicative. The surface area that has legal significance in a coproperty sale continues to depend on the calculation method set by the Law of Property Management (Loi Carrez), regardless of the tool used to produce the listing plan (Légifrance).
Our comprehensive guide to estate plans for listings details what this plan must include and where its legal value ends in relation to the Law of Property Management; the scan and editing tutorial demonstrates the concrete steps, piece by piece.
How to Choose Based on Your Mandate Volume
The right choice isn’t universal: it depends on your actual activity rhythm, not intent.
- Fewer than 5 plans per year: a one-off provider or free software remain the simplest options to implement, with no commitment or tool change.
- Between 5 and 20 plans per year: the calculation gets tight. The time spent on free software is starting to weigh, but without enough to justify a dedicated subscription — this is the zone where detailed comparison of your actual figures (real time, implied hourly rate) makes the difference.
- More than 20 plans annually: an integrated tool with the plan included in the subscription already paid for photos becomes almost always the cheapest option, in euros and hours.
The most reliable benchmark remains your own historic data from the past twelve months — not a national average: a rural agency with fifteen mandates per year and an urban one with a hundred are not in the same situation.
Field observations from agencies using IACrea suggest that switching to an integrated tool is rarely decided by cold quotes. Often, it happens after missing a plan on a tight mandate — the one where the provider couldn’t schedule an appointment within ten days — and then calculating what this delay cost in lost visits.
FAQ
How much does a real estate 2D plan ordered from a provider typically cost?
Two very different scenarios. A standardized plan ordered online, without visiting the property, ranges between €350 and €1,000 depending on options. A full architectural survey carried out on-site by a surveyor (plans, sections, facades in DWG) costs more, usually €890 to €3,750 excluding VAT, because it includes travel and a higher technical level than a simple listing.
Is a free 2D plan software truly free?
Free to buy, not free in time. Count on one to three hours per property to measure on-site and input the data into the software, plus time for adjustments for missed measurements. This can weigh heavily in an agent’s schedule over twenty mandates annually, even if no invoice is issued for those hours.
From how many mandates per year does an subscription with an included 2D plan become worthwhile?
As soon as a monthly subscription with an included plan costs less than paying for each plan individually multiplied by your volume, which generally happens around five to eight properties per month for an active agent. Below that, a one-off provider or free software remains justifiable; beyond that, the zero marginal cost of the subscription almost always wins.
Does the price of a plan depend on the property’s surface area?
Yes, with an external provider: larger surface areas and more rooms mean longer on-site measuring and a higher quote, often with an additional fee beyond a certain size or number of floors. This isn’t the case with an included plan in an abonnement, where the marginal cost remains the same regardless of property size.
Is a plan generated by a smartphone app the same price as a surveyor’s plan?
No, and it’s also not the same purpose. The scanned plan costs much less — often just the subscription fee already paid — but delivers indicative surfaces suitable for a listing, not for a legal measurement affecting the sale. The price reflects their different aims: convincing a buyer doesn’t require the same precision as securing a notarized act.
Conclusion
There’s no single price for an estate 2D plan, but three cost logic approaches, each suited to a different activity volume: occasional work with a provider, time-efficient free software, or a volume-based integrated subscription. The right choice is discerned from your own mandate history, not a solitary quote.
If your volume already exceeds a few properties per month, the calculation tends to favor a tool that includes the plan without separate billing. Compare your numbers with our pricing and try scanning on your next mandate: five minutes is enough to see if the approach fits your agency.
