If you already own a plot, a design-and-build firm can take you from an empty site to a finished house with one team. The benefit is that the people drawing your house are also the people pricing and building it, so the design stays within budget and buildable details are sorted early.
What is included
| Stage | What the firm does | You provide |
|---|---|---|
| Plot survey | Measures plot, levels, road width, neighbouring structures | Plot documents, access |
| Byelaws review | Checks setbacks, coverage and height for your authority | Society or authority name |
| Concept design | Layout options and elevation within budget | Your brief and budget |
| Detailed drawings | Architectural, structural, electrical, plumbing | Approvals of each stage |
| Approval support | Prepares and submits the drawing file | Ownership papers, fees |
| Construction | Grey structure and finishing as agreed | Stage payments |
| Handover | Snag list, documents, utility connection support | Final inspection |
When you need it
- You own a plot and want one accountable team.
- You live abroad or cannot supervise daily.
- You want cost estimates while the design is still flexible.
Step-by-step process
- Share plot details – location, size, documents and budget range.
- Survey – the firm visits, measures and photographs the site.
- Byelaws and brief – confirm what you can legally build and what you want.
- Concept with cost – layout options with an early estimate for each.
- Design freeze – final drawings and specification sheet.
- Approval – submit drawings. In LDA areas, building plan approval runs through the Punjab e-Biz portal under LDA's Building and Zoning Regulations 2019; DHA and private societies use their own processes.
- Contract – scope, specification, rate or lump sum, payment stages, timeline.
- Build – grey structure, then finishing, with inspection points.
- Handover – snags fixed, keys and documents handed over.
Documents usually involved
- Plot ownership documents (allotment, transfer or registry, as applicable).
- Owner's CNIC.
- Site plan or demarcation from the society or authority.
- Approved building plans before construction begins.
- Later, applications for LESCO electricity and SNGPL gas connections where available.
Ask your authority or society for its current list; requirements differ between LDA, DHA and private schemes.
What affects the cost
Design fees may be charged separately or bundled into the construction rate. Construction is usually priced per sq ft of covered area or as a lump sum. Published Lahore ranges in Houseplot construction rate data (October 2026) are about Rs2,200–4,000 per sq ft for grey structure and Rs6,500–13,450 per sq ft for a complete house. Factors:
- Plot size, shape and corner or park-facing position.
- Floors, basement and covered area.
- Soil and foundation needs.
- Elevation and finishing specification.
- Whether design, approval fees and external works are included.
Questions to ask
- Do you have an in-house architect and structural engineer? Are they PCATP and PEC registered?
- Will you give cost estimates at concept stage?
- How many design revisions are included?
- What happens if approval asks for drawing changes?
- Who owns the drawings if I part ways after design?
- What is the payment plan for design versus construction?
Red flags
- Design offered "free" with no written scope, locking you in.
- No byelaws check before concept design.
- Encouragement to build extra coverage or floors beyond approval.
- No separate line for authority fees and who pays them.
- Drawings not signed by a named engineer or architect.
FAQs
Can I take the design to another builder? Only if your contract says you own the drawings after paying the design fee. Agree this before you start.
Do I need a plot survey if I have the society map? Yes. Actual plot size, levels and neighbouring structures can differ from the map, and the design must match the real site.
Who applies for approval? The firm usually prepares and submits the file, but the application is in the owner's name.
Can design and build work for a renovation? Yes, though the process starts with a survey of the existing structure and its drawings.
