A 100 by 100 foot plot measures 30.48 metres by 30.48 metres.
Its area is 10,000 square feet, which is about 929 square metres or 0.23 acre. The perimeter is 400 feet, or about 121.9 metres.
In Kenya, 100 by 100 is often described loosely as a quarter acre. An exact quarter acre is 10,890 square feet, or about 1,012 square metres, so a true 100 by 100 foot plot is roughly 8% smaller.
| Measurement | 100 by 100 ft plot |
|---|---|
| Dimensions | 30.48 m × 30.48 m |
| Area | 10,000 sq ft |
| Area | 929 m² |
| Acres | 0.23 acre |
| Perimeter | 121.9 m |
If you are budgeting specifically for an exact quarter acre, use our quarter-acre fencing guide. The estimates below are for a 100 by 100 foot plot with a perimeter of about 122 metres.
Barbed Wire: Ksh 12,500 to Ksh 39,500
Still the cheapest route. Three strands around a 122-metre perimeter require about 366 metres of barbed wire before allowing for tying and wastage. If the roll you are buying is 600 metres, one roll is enough. You’ll need roughly 25 posts at about 5-metre spacing before adjusting for corners and the gate.
Two workers, two days, Ksh 2,000 to Ksh 4,000 for labour.
Chain Link: Ksh 35,500 to Ksh 111,000
At Ksh 250 to 500 per linear metre, about 122 metres of chain link costs roughly Ksh 30,500 to Ksh 61,000 before posts and other materials. Add posts, straining wire, binding wire, concrete where required, the gate, transport and labour.
If the chain link comes in 30-metre rolls, 122 metres requires a little over four rolls, so budget for 5 rolls unless the supplier cuts mesh to length.
Live Hedge: From Ksh 10,000
A live hedge can reduce the initial material cost, but the final amount depends on plant spacing, species, transport and establishment. Many owners pair a hedge with wire fencing while it grows. Ongoing watering, trimming and replacement costs should also be considered.
Stone / Concrete Wall: Ksh 230,000 to Ksh 460,000
At Ksh 1,500 to 3,000 per linear metre, about 122 metres of walling gives a broad material estimate of roughly Ksh 183,000 to Ksh 366,000 before the full foundation, columns, finish, gate work, transport and labour are confirmed.
Wall specifications vary significantly, so compare quotations only when they cover the same height, foundation, reinforcement, finish and gate scope.
Side by Side
| Type | Broad planning range |
|---|---|
| Barbed Wire | Ksh 12,500 to 39,500 |
| Chain Link | Varies by mesh gauge, height, posts and labour |
| Live Hedge | Varies by species and spacing |
| Stone / concrete wall | Varies by wall specification and foundation |
Before You Start
Confirm your plot boundaries with a licensed surveyor before you fence. Boundary disputes are common and expensive. Also check with your county government if you need a construction permit for a perimeter wall.
And don’t forget to budget for a gate. It’s the one thing people always leave out of their fencing estimates.
