How Much Do House Plans Really Cost?

A stock house plan usually costs a few hundred to a few thousand dollars. At Morava Modern, a Study Set is $149–$299, a Complete Set with DWG files and a single-build license is $799–$1,995, and a Studio Set is $1,795–$3,295, by size. Adaptation and construction are separate, priced where you build. Here is how to budget for all three.

Cost one: the design

This is what you pay for the design itself. For stock plans, five things move the price:

Size. A larger house means more drawing and more coordination, so most sellers, us included, price by size.
Completeness. A study or presentation set is not the same as a full set with dimensioned plans, elevations, sections and schedules. Compare sheet lists, not headlines.
File format. PDFs are for reading and printing. Editable DWG files let your local professional work directly from the drawings instead of redrawing them.
License. Most plans are licensed for one build. Building the same design twice, or as a developer, costs more.
Support. Modifications, and answers while your local team adapts the design, take time, and some sellers include them.
Visualization. 3D interior renderings and 360° tours are usually quoted separately, per view or per room.

Our own prices are fixed and published on the pricing page, set by four size bands based on the published design area, in three tiers:

The Study Set is a PDF set with no build license, for evaluating a design with a local professional before you commit. Its full price is credited toward the same design's Complete or Studio Set within 12 months.
The Complete Set adds DWG files and a single-build license.
The Studio Set adds a capped round of non-structural modifications before handover and Q&A time with your local professional over 12 months.

Size band	Study	Complete	Studio
Compact, up to 120 m² (1,292 ft²)	$149	$799	$1,795
Family, 121–200 m² (1,293–2,153 ft²)	$199	$1,195	$2,295
Signature, 201–300 m² (2,154–3,229 ft²)	$249	$1,595	$2,795
Estate, over 300 m² (3,229 ft²)	$299	$1,995	$3,295

Prices are in US dollars, before tax. Other currencies on the site are approximate, and you are invoiced in USD. You send an order request, we confirm the exact sheet list for the design in writing with your quote, and nothing is charged before that confirmation.

How much do house plans cost per square foot?

A Complete Set here works out at about $0.46 to $1.14 per sq ft, depending on size: $799 for the 700 sq ft Prism, $1,995 for the 4,306 sq ft Altura. The larger the house, the lower the price per square foot.

For comparison, single-build US stock plan sets with CAD files that we reviewed in September 2026 were listed at roughly 700 to 2,100 US dollars.

Price per square foot is a handy way to compare catalogs, but a plan that looks inexpensive per square foot may leave out sheets your local professional will then have to create, at their rates. Compare what is included, not just the headline figure.

Cost two: local adaptation

Every stock plan needs work before it can be built on a particular site, and a design drawn in another country needs more. Our designs are drawn in metric by CAD ART studio in Serbia, following Serbian and EU practice. They are not stamped or approved for any location.

The adaptation is carried out by a professional licensed where you build, and typically covers:

structure and foundations for your soil and climate;
energy compliance and any calculations your jurisdiction asks for;
heating, plumbing and electrical design;
a site plan, drainage and access;
conversion to feet and inches where your trades expect it;
the permit or planning application, and answers to the questions it raises.

Around the adaptation sit other early costs: a land survey, a soil investigation, application fees and utility connections. They vary widely by location, and none of them is part of any plan price, ours or anyone else's.

This is the cost most buyers forget, and there is a simple cure. Before committing to a full set, buy the Study Set, show it to a local professional and ask for a written quote for the adaptation. A modest first step turns the biggest unknown into a number.

Cost three: construction

Construction is by far the largest of the three, and it is the one we never quote. It depends on your location, local labor and materials, the finishes you choose, the ground and access on your site, and the market in the months you build. A figure given without your site and your local market is only a guess. The people who can price it properly are local builders and, in the UK and Australia, quantity surveyors, working from the adapted drawings.

What you can do early is understand which design choices move that number:

Footprint shape. Every extra corner adds foundation, wall and roof edge. A compact form with two similar floors stacked on top of each other, like Terracotta with 70 m² (753 ft²) on each level, is simpler to build than a long, many-cornered single level.
Levels below ground. Basements and walkout levels on sloping lots add excavation, retaining and waterproofing.
Glazing. Large sliding glass walls, a signature of contemporary European homes, cost more than standard windows.
Spans and cantilevers. Deep overhangs and cantilevered slabs are beautiful and need more structure.
Cladding. Stone and travertine-look cladding cost more than render. A good builder can price alternatives that keep the character.
Roof form. A flat roof trades framing for careful waterproofing, insulation and drainage.

None of these is a reason to avoid a design you love. They are the questions to ask your builder, so that you can decide where to spend and where to save.

Budgeting in the right order

Set a realistic overall budget with local builders or a quantity surveyor, using their current guidance for your area.
Shortlist designs that fit both the budget and the lot.
Buy the Study Set for your favorite, and get a written adaptation quote from a local professional.
Ask a builder for a preliminary estimate from the Study Set drawings.
Move up to the Complete or Studio Set once the numbers work, with the Study Set price credited, then price the build again on the adapted drawings.

Keep a contingency throughout. Your builder or quantity surveyor can suggest how much for your type of project.

Stock design or custom design?

A stock design lets you see the finished design before you pay for it, costs less than designing from scratch and saves months at the start. A custom design fits a particular site and brief exactly, and costs more and takes longer. Between the two, the Studio Set covers modest changes such as layout adjustments, openings and finishes, within a capped allowance.

If your site or your brief is unusual, custom design is quoted separately, with a fixed quote within 2 business days once you've sent your brief. If budget is the main constraint, the small homes collection is a good place to begin. And the how it works page explains each step, from first question to delivered files.
