How Much Does a Floor Plan Cost? What Changes the Number4

A Floor Plan Design from Sunvega Design starts at $400. The $400 base covers the first 400 m² of planned floor area across all levels; area above that is charged at $1/m². Angi's 2026 cost data puts the national average near $1,300.

Published prices vary by who draws the plan

Angi puts the national average for professional floor plan services at $1,300, with most homeowners paying $500–$2,000. That range covers a drawn plan; it does not say what the plan includes. A floor plan can mean a layout sheet, a set of construction drawings, or a service that adds exterior views, plumbing, electrical and local review. The scope check comes before the price check.

Option	Published price	What the buyer gets
Professional floor plan service (Angi)	$500–$2,000 typical; $1,300 average	A drawn plan; scope varies by provider
Sunvega Design Floor Plan Design	Starting at $400; $1/m² above 400 m²	Room functions, layouts and dimensions for each floor; wall, door, window and stair annotations; DWG + PDF

Architect-led design can cost more than a drafting service. The relevant question is not only who draws the plan, but which drawings and local-review steps are included.

A floor plan quote can cover five different modules

The official Sunvega service page lists five modules. Each answers a different part of the work, and each is priced separately.

Module	Price	What it delivers
Floor Plan Design	Starting at $400	Room functions, layouts and dimensions for each building floor; spatial layout of floor plan units and annotations for walls, doors, windows and stair dimensions; DWG + PDF
Exterior Render Design	$600	Five fixed exterior views: front, rear, left-front, right-rear, bird's-eye
Architectural Construction Design	$600	Architectural design description, construction elevations, cross-sections, door and window schedules, stair drawings, kitchen and bathroom details, and detail drawings
Plumbing Construction Design	$600	Plumbing design description, water supply and drainage for bathrooms, kitchens and balconies, roof rainwater discharge, septic tank design, pipe connections and installation requirements
Electrical Construction Design	$600	Strong-current, weak-current and lightning-protection design descriptions; lighting layouts for each floor; air-conditioning, socket and television designs

The quotation lists 15–22 sheets for the architectural module, 8–12 for plumbing and 8–12 for electrical. The full set is 45–65 sheets.

Each module answers a different question:

• Is the room layout right? Floor Plan Design, starting at $400.

• What will the house look like from outside? Add Exterior Render Design, $600.

• Which architectural details will the builder need? Add Architectural Construction Design, $600.

• Does the local review need plumbing or electrical layouts? Add the relevant module, $600 each.

Bought together, the five modules total $2,800 and cover 45–65 sheets. The $400 plan is one module, not a discounted set. Before payment, Sunvega Design reviews the building area and selected services, then confirms the final quotation. See residential architecture projects for examples of the finished work.

What the $400 plan includes

The $400 Floor Plan Design provides precise planning of room functions, layouts and dimensions for each building floor. It includes the spatial layout of floor plan units and annotations for walls, doors, windows and stair dimensions. Sunvega Design delivers the drawing as a DWG file and a PDF set, so the same plan can be edited and shared.

• Room functions and layout for each floor

• Dimensions for rooms, walls and openings

• Wall, door, window and stair dimensions

• DWG and PDF delivery

The floor plan is the base for the other modules. Construction elevations and details are drawn from it, which is why the floor plan comes first in the set.

What the $400 plan does not include

Floor Plan Design covers layout, dimensions and annotations. It does not include the construction drawings in the $600 Architectural Construction Design module: construction elevations, cross-sections, door and window schedules, stair drawings, kitchen and bathroom details, or detail drawings. Plumbing and electrical construction drawings are separate $600 modules.

Sunvega Design is an online design team. Its pricing does not include signing or stamping from a locally registered architect or engineer. Local approval, review, or stamping is not included either; a separate architect or engineer licensed in the client's jurisdiction must review the files and complete the required process before construction.

The $600 architectural, plumbing and electrical modules are also drawn by Sunvega's online design team. The local architect or engineer is involved only for review, signing and stamping.

These exclusions apply to Sunvega Design's plan pricing. The plan fee is not the cost of getting a house built.

A homeowner who only needs room layout pays for one module. One preparing drawings for a local review buys the modules that review requires, still drawn by Sunvega's online team, then has a separate architect or engineer licensed in the client's jurisdiction review and stamp them.

Before ordering, ask the local building department which drawings the submission needs. If elevations, sections or schedules are required, add the $600 Architectural Construction Design module. The Sunvega Design team prepares each selected module; see the designers behind the drawings.

What moves the price: area, module scope, revisions and local review

Four things explain most of the difference between two quotes: area, module scope, revision rounds, and the drawings the local review requires. Area follows the clearest rule. $400 covers the first 400 m² of planned floor area, and every square metre above that is $1, whichever floor it sits on.

Variable	How it changes the number
Area	First 400 m² included; $1/m² above that
Module scope	Each additional module is $600
Revision rounds	Two rounds are included; consolidate feedback per round
Local review	Signing, stamping, approval and review are not included; a separate architect or engineer licensed in the client's jurisdiction handles them

The published delivery timeline is five days up to 4,000 sq ft, ten days from 4,000 to 8,000 sq ft, and fifteen days above 8,000 sq ft.

Where floor plan budgets go wrong

Two common buying mistakes are cheaper to catch before ordering than after the first builder quote.

Assuming $400 covers the whole house whatever its size. The base quotation covers the first 400 m² of planned floor area. A house of 600 m² over two floors (300 m² each) is 200 m² above the base, which adds $200 at $1/m², for a total of $600.

Taking a layout sheet to a local review. A layout plan alone is usually not enough where the local review requires elevations, sections or door and window schedules. The $400 plan does not include them; they are in the $600 Architectural Construction Design module. Stamping still requires a separate architect or engineer licensed in the client's jurisdiction.

Confirm two things before ordering: which drawings the quote covers, and which drawings the local review needs. Both problems are avoided that way.

How to compare two floor plan quotes

Two quotes for the same house can differ by thousands of dollars without either being wrong. Six questions separate them: area basis, floors, drawings, file formats, revisions and local review.

1. Area basis. Is the base area measured in m² or sq ft, and what does the quote charge above it?

2. Floors. Is the price based on floor area, or charged per level?

3. Drawings. Is it a layout sheet only, or does it include elevations, sections and schedules?

4. File formats. DWG, PDF, or both? A PDF alone limits later edits.

5. Revisions. How many rounds, and what happens after the last one?

6. Local review. Is signing, stamping or local approval included, or is that a separate step with a locally registered architect or engineer?

A quote that answers all six can be compared with another. A quote that answers only the price cannot be compared.

Sunvega Design's Floor Plan Design starts at $400 for the first 400 m², plus $1/m² above that, with DWG and PDF delivery and two revision rounds. Submit your building area, floor requirements and design preferences to start a quote, or review architectural design services for the full module list.

FAQ

Does the $400 plan include elevations? No. Construction elevations are part of the $600 Architectural Construction Design module, which also includes cross-sections, door and window schedules, stair drawings, kitchen and bathroom details, and detail drawings.

Does the $400 plan include CAD files? Yes. Sunvega Design delivers the floor plan as a DWG file and a PDF set, so the drawing can be edited and shared.

Is there an area limit, and what would a 5,000 sq ft plan cost? There is no maximum area. The $400 base covers the first 400 m², and area above that is charged at $1/m². A 5,000 sq ft house is about 465 m², so the extra 65 m² adds about $65, for a total of about $465.

Is the $400 plan enough to build from? No. It is a layout and dimension plan, not a construction set. Construction elevations, sections and schedules are in the $600 architectural module; plumbing and electrical layouts are separate $600 modules. All are drawn by Sunvega's online team. Signing, stamping and local approval are handled by a separate architect or engineer licensed in the client's jurisdiction.
