Poyful

Clear plans for buildings, software and products.

Poyful is a small studio run by a civil engineer and an architect. We take on design, engineering and software work for clients anywhere, and we make our own digital and printed products.

Poyraz is the north-east wind our name comes from. The lines above move with it. Registered in Wyoming, USA. Working with clients worldwide.

  • Engineer and architectTwo disciplines under one roof, on every project.
  • PhD in structural engineeringAnalysis, cost and code checks done properly.
  • In the field since 2002Public buildings, site supervision and contracts.
  • English and TurkishRemote work, delivered as digital files.

What we do for clients

Three kinds of work, each quoted at a fixed price before we start. You get the files, the working files where agreed, and a person who answers your questions.

Architectural design and visualization

From a first sketch to drawings and images you can show a buyer, a lender or a builder. We plan the spaces, model them in 3D and render them so the design can be judged before money is spent on it.

Suited to homeowners, developers and small practices that need extra drawing or rendering capacity.

What you receive

  • Concept design and floor plans
  • 3D models and interior concepts
  • Photorealistic renders and walkthrough videos
  • Presentation boards and sales catalogues
  • DWG
  • RVT
  • SKP
  • PDF
  • JPG
  • MP4

Structural and building engineering

Independent checks and numbers you can rely on. We build analysis models, review existing calculations, measure quantities from drawings and prepare cost estimates, with every assumption written down.

Suited to owners, contractors and designers who want a second pair of eyes on structure, quantities or cost.

What you receive

  • Structural analysis models and design reviews
  • Seismic assessment and strengthening reports
  • Quantity take-offs and bills of quantities
  • Cost estimates and progress payment checks
  • SAP2000
  • PDF
  • XLSX
  • DWG

Software and automation

Small, focused software that removes a repeated job. We connect the tools a business already uses, build simple web apps for a single task, and publish mobile apps. Plans first, code second, documentation always.

Suited to small firms and studios, especially in design and construction, that lose hours to manual steps.

What you receive

  • Web tools and internal dashboards
  • Workflow automations between your apps
  • AI-assisted document and drawing pipelines
  • iOS and Android apps
  • Web
  • iOS
  • Android

Our drawings and calculations are design and consulting documents. Where a building permit or construction requires the stamp of a licensed engineer or architect, a professional licensed in that place must review and sign them. We are glad to work alongside yours.

Things we make and sell

Alongside client work we design our own products. Every design is original and made in-house. Our first collection is in preparation.

Digital downloads

Templates, planners and drawing libraries for architects, engineers and site teams, ready to use the moment you download them.

In preparation

Printed products

Posters and apparel made from our own artwork, printed to order by production partners and shipped straight to you.

In preparation

Apps

Small iOS and Android tools for people who plan, build and keep track of things, starting with problems we know from our own work.

Where the name comes from

Poyraz, the north-east wind, plus the English ending -ful, meaning full of, makes Poyful.

The eight winds of the Turkish wind rose, with Poyraz, the north-east wind, highlighted Yıldız Kıble Gündoğusu Günbatısı Keşişleme Lodos Karayel Poyraz NSEW

Poy, from poyraz

In Türkiye the winds have names. Poyraz is the one from the north-east: cold, strong and dry. When it has passed, the air is clear and you can see a long way.

Ful, from full

The second half is the English ending you find in joyful, playful and careful. It means full of. Put together, Poyful means full of poyraz: work with fresh air in it, clear and quick, and done with care.

That is what we want our work to do. A drawing that answers the builder's question before it is asked. A cost estimate with no surprises in it. A small piece of software that takes a step out of someone's day.

The logo

The P stands upright like a column. Inside its round bowl a breeze begins thin, gathers body and turns inward: a P full of fresh air, which is what the name means.

Who runs Poyful

Yılmaz D., Ph.D.

Founder

  • Civil engineer, M.Sc. and Ph.D.Doctorate in structural engineering
  • Computer engineerSoftware, automation and data
  • Nearly twenty years in practiceDesign review, cost estimating and site supervision

Poyful was founded by Yılmaz D., a civil engineer with a doctorate in structural engineering who is also a computer engineer.

He has spent nearly twenty years on building projects: checking designs, measuring quantities, estimating costs and supervising work on site. Alongside that he builds the software and automations that make this work faster and harder to get wrong.

Poyful is where the two meet. Engineering judgment on one side, and the skills to turn it into drawings, tools and products on the other. On architecture projects he works with an experienced architect.

Working with us

The practical details, so there is nothing to guess.

Payment

Prices are fixed in U.S. dollars. You pay through a secure online invoice by card or bank transfer: a deposit to start and the balance on delivery.

Communication

We reply within one to two business days, in English or Turkish. Calls are by video and scheduled to suit your time zone.

Files and confidentiality

Your drawings and data are used only for your project. We sign a confidentiality agreement on request, and we never show client work without permission.

Questions people ask

Can you stamp drawings for a building permit?

No. We prepare design, analysis and review documents. A stamp for a permit or for construction has to come from a professional licensed where the building is. Many clients use our work as the basis and have their local engineer or architect review and sign it.

How much does a project cost?

Every project gets a fixed quote after we read the brief, so the price depends on the scope. The quote lists exactly what is included, the number of revision rounds and the delivery date. It costs nothing to ask.

How many revisions are included?

The quote states the number of revision rounds, usually two. Changes outside the agreed scope are quoted separately and only done after you approve them.

Do I get the working files, such as DWG or RVT?

Yes, when the quote includes them. Once the project is paid in full, the rights described in the quote pass to you.

Do you work with clients outside the United States?

Yes. All of our work is delivered digitally, so we can work with clients anywhere. For engineering work we tell you at the start which design codes we will use.

Do you use AI tools?

Yes, as tools. We use software, including AI assistants, to speed up drafting, checking and automation. Every deliverable is reviewed and finished by us, and products that include AI-assisted work are labeled wherever a marketplace requires it.
