Open Shed Construction
Dairy Farm Construction in Pakistan
Pioneers of PEB Dairy Shed in Pakistan
The open shed is the most popular dairy housing in Pakistan. A high steel roof gives shade and rain cover while the open sides let natural air pass through, which keeps cows cooler and the shed drier.
What is an open shed?
An open shed is a steel framed roof structure with no side walls, or only low walls, built over feeding lanes, free stalls and walkways. Because air moves freely, heat and ammonia do not build up, and animals stay more comfortable in Pakistan's hot and humid months. It is also the lowest cost way to cover a large herd.
Mahmood Engineering pioneered PEB dairy sheds in Pakistan. Each shed is engineered for your herd size, with the correct roof height, slope and ridge opening so hot air escapes from the top while the floor stays dry.
Best suited for
- Farms with 50 to several thousand animals
- Hot regions where natural airflow is enough
- Buyers who want the lowest cost per animal
- Fast construction with easy future expansion
- Cows and buffaloes in loose housing
What is included
- Pre-engineered steel portal frames
- Roof sheeting with ridge ventilation
- Roof lights for natural daylight
- Feeding manger and neck rail
- Free stalls and dividers on request
- Floor slab, drainage and alley slopes
- Water troughs and fittings
- Optional fans and sprinklers for peak summer
How we do it, A to Z
A clear process with a named engineer at every stage, so you always know what happens next.
Site visit and requirement study
Our engineer visits your land, checks soil, drainage, wind direction and access roads, and records your herd size, milking routine and expansion plans.
Day 1 to 5Layout and concept design
We plan feeding lanes, resting area, alleys, water points, milking route and manure flow so animals and workers move without crowding.
Week 1 to 2Structural design and drawings
Portal frames, purlins, bracing and foundations are designed for Pakistan wind and seismic loads. You receive approved drawings before steel is cut.
Week 2 to 4Quotation and agreement
A clear bill of quantities, material grades and payment schedule. No hidden items, and every change is priced before it is built.
Week 3 to 4Foundation and civil works
Excavation, footings, plinth beams and floor preparation, with anchor bolts set to exact positions for the steel frame.
Week 4 to 8Fabrication in our factory
Columns, rafters and purlins are cut, welded and painted or galvanised at our Lahore factory under quality control, then marked for fast assembly.
Week 4 to 10Erection and roofing
Frames are lifted and bolted, purlins and bracing fixed, then roof sheets, ridge ventilation and roof lights are installed.
Week 8 to 14Finishing, inspection and handover
Floors, mangers, rails, water troughs and drainage are completed. We inspect every connection and hand over with drawings and maintenance advice.
Week 12 to 16See it in 3D
Rotate the open shed, zoom in, or walk inside along the feeding lane.

Common Questions About Open Shed
The cost depends on covered area, roof height, steel grade, floor works and equipment. An open shed is the most economical option. Share your herd size and location through our estimate form and we will send a clear quotation.
With free stalls and feeding lanes, a typical layout needs about 100 to 110 square feet of covered area per animal, including alleys. Exact numbers depend on your layout and whether you add a holding area.
In most of Punjab and Sindh, yes, when the roof is high and the ridge is open. For extreme heat we can add fans and sprinklers over the feeding lane, or you can choose a control shed.
Yes. Our PEB frames are designed in bays, so you can add more bays at the end of the shed when your herd grows.
