Architecture + MEP Engineering. One Firm. One Contract. Permit-Ready.

QD Design is a HUB-certified architecture and engineering (A/E) design firm based in Cypress, Texas, serving Houston, Austin, Dallas–Fort Worth, and San Antonio, with completed projects in Florida and Minnesota. We produce the complete permit set — architectural drawings plus sealed mechanical, electrical, and plumbing (MEP) engineering — under one contract, led by a Texas-licensed Professional Engineer. No coordinating between separate firms. No finger-pointing when plan review comes back.

Send us your floor plan and you’ll have a fee proposal within one business day.

Why Owners and Contractors Choose QD Design

  • One firm, whole permit set. Architecture, mechanical, electrical, plumbing — plus civil and structural coordination — from a single design team. On our 17,000 SF medical clinic campus in Houston, all six disciplines ran under one contract.
  • Fast-track speed. On a 25,250 SF industrial renovation in Houston, schematic design was approved 7 days after signing and the full design was permitted on a 3–4 week schedule.
  • Jurisdiction fluency. We answer plan-review comments for a living: City of Houston DSD, Austin, Sugar Land, Pearland, Tomball, League City, Euless, Harris and Fort Bend Counties, TDLR/TAS accessibility. A Sugar Land school kitchen with three parallel reviewing agencies went from first submittal to permit in about 30 days.
  • 200+ completed projects. Restaurants, medical and dental clinics, retail, daycare and schools, churches, warehouses, senior living, and pharmaceutical cleanrooms.
  • HUB / minority-owned certified. Your project may qualify for diversity participation credit.

Frequently Asked Questions

Do I need both an architect and an MEP engineer for a commercial permit?

In most Texas cities, yes — commercial permits require architectural drawings plus sealed mechanical, electrical, and plumbing plans. QD Design provides both in one package, which removes the most common cause of permit delays: coordination errors between separate firms.

How fast can you produce permit drawings?

Typical commercial tenant-improvement packages run 3–5 weeks from contract to submittal. We have delivered approved schematic design in 7 days on fast-track projects.

Which cities do you work in?

All of Texas — most frequently Houston, Cypress, Katy, Sugar Land, Pearland, League City, Tomball, Humble, Austin, Dallas–Fort Worth, and San Antonio — plus projects completed in Florida and Minnesota. See our service areas.

What does design cost?

Fees depend on square footage, project type, and scope (architecture only, MEP only, or full A/E). Send your floor plan and we’ll quote it within one business day — most clients find one combined A/E fee costs less than hiring two firms.
