Land Use in Kenya. Nairobi and its environs.

Kenya land was first appropriated by the British colonists in the 1890s. All land in Kenya was then taken to be the property of the British colonists.

In the 1920s, Britain then marked out the most productive land in Kenya, which is around 20% of Kenya’s land mass and sold it to British citizens in 1,000 acre chunks. These areas were referred to as the White highlands, namely central province, Rift Valley province and parts of Kitale.
Kenya land size is 144 million acres.
20% OF this land is arable, i.e 29 million acres.

At attainement of independence in 1963/1964, land onwership change from the British to indigenous Kenyans was crafted.
A solution known as the 1 million acre settlement scheme was hatched by the British and Kenya Governments whereby Kenyans were to buy back the land from the white settlers.

This was funded by world bank.

The Swynnerton Plan, hatched in the 1950s, aimed at creating a middle and upper class indigenous Kenyans in central province. This was to be achieved by enabling a few central province Kenyans to own large tracts of farm land previously owned by the colonists then they employ the large masses of people.

http://en.wikipedia.org/wiki/Swynnerton_Plan

The British implemented the Swinnerton plan from the mid 1950s by rewarding loyalist Kenyans with large swathes of land and encouraging them to get into cash crop farming.
The over emphasis on cash crop farming would in later years lead to lack of food since food crops were not being planted.

The British land alienation policies which were not well designed to offer indigenous Kenyans access to land led to massive relocation of Kikuyu landless people into the Rift Valley former white highlands.

Current land situation in Kenya.

British interests and Government still continue to hold large chunks of viable land around Nairobi and within the white highlands.
Delamere owns 100, 000 acres from Naivasha till Nakuru. Large British tea holdings still own large acres of land.
A few indigenous Kenyans who were favoured by the British colonists and rewarded with huge chunks of land around Nairobi still own. Some of them have resold the land to other people.

Way forward.
The National Land Commission should come up with land use policies that ensure these large land owners are forced to utilise the land .This can be done through implementing taxes on idle land. This will force these owners to either ensure the land is used productively, hence offering employment or the land is sold to those with the entrepreneural skill to utilise it.
It is really not a big deal as to who owns the land so long as the Government can ensure they are Kenyan citizens and are using the land to create employment.
Agricultural areas around Nairobi such as Kiambu should be taxed higher so that the tax revenue raised can be used to support green house agriculture and irrigation in the arid areas.

Plastics in the Construction industry.

Plastics are gaining entry itto main construction industry.
We have the new uPVC ceilings, wood plastic wall and column coverings,uPVC floor coverings and PVC material used for roof.
Its just a matter of time before an enterprising industrialist comes up with interlocking plasctic boxes that can be filled with soil and be stacked and joint together to form structural walls.
This will solve alot of problems.
This will make construction of walls and roofs much cheaper.
This would also enable soil that cant be used to create stabilised soil blocks, eg black cotton soil or sandy/salty shoreline sand, be useful in construction as an insulating infill inside the plastic interlocking containers.
This would also provide a method of recycling plastic.
It can be moulded into various patterns, colours and textures.

The plastic bricks interlock just like in a LEGO toy to create walls.

Interested venture capitalists/plastics manufacturers can get in touch so that we develop this into a commercially viable alternative construction method in Kenya.

The usual Roto tanks supporting thousands of liters of water show that plastics are strong enough to be used for walling since walls dont support heavy loadings except roof loading.

Plastic wallings can also be used to create vertical wall gardens, complete with internal watering systems.

Plastics for Roofing.

PVC sheets are a common roof feature for bars,restaurants,churches and out door tents all over Kenya.

Use of PVC for roofing can be creatively introduced into residential housing. This can be used as an outdoor living area extension.
Use of different pvc roofing sheet colour generates a desirable ambience to the space within it.

For example, the outdoor sitting area for the Ehiopian restsurant at Utalli House in Nairobi CBD has a red colour which makes the interiors very exiting.

Rafikiz restaurant along Langata road also has utilised an interesting pvc roof design.

Tulips restaurant, Kileleshwa, designed by a4architect.com, is also a good example of pvc roofing being used to extend living areas of permanent buildings.

3 D printing of Buildings.

Research into making building construction more efficient using 3 d printing is on going . Soon we would be able to print our buildings directly from our computers.
This technology is the latest in the field of construction.
Dr. Behrokh Khoshnevis of the University of Carlifornia is leading this research through a method called contour crafting.

In this method, a giant 3 d printer with a moveable flexible arm pours and moulds concrete from a pre mix concrete lorry along the contours of the building wall, slab , roof and other elements.

The moveable arm interweaves the concrete to form a firm wall structure.
Currently, concrete is the most widely used construction material.Ways and methods of making the concrete cheaper, such as creating fibre cement, can be utilised to reduce costs for bungalow type buildings that don’t require heavy structural walls.

The robotic arm of the 3d printer can be controlled to print exactly as drawn on the computer.

Currently, concrete prefab panel construction is made costly due to need for cranes to lift the heavy panels to the higher levels. With 3d printed buildings, there is no need for this since the pre mix lorry concrete pump will pump to the higher levels.

Watch this video here on how the technology works.

For Kenyan situation, much customisation will have to be done for this to be practical. Pre mix concrete lorries are already available here. The robotic printing arm design and programming will need to be undertaken by say, Numerical Machine Complex or any other private sector industry with a knack for innovative technology.

A person can aid the printer to ensure it works perfectly till the mechanisms are fine tuned to perfection.

Housing costs in Kenya. Why cost of acquiring a home in Kenya is high.

Housing costs in Kenya.  Why cost of acquiring a home in Kenya is high.

On average, Kenya has one of the lowest construction rates in the world. Kenya also has one of the highest land prices in the world, much higher than in developed countries such as USA.

Housing cost can be divided into 3 basic categories.

1.Low cost

2.Middle cost

3.High cost

Low cost housing.

This costs an average of kes 20,000 per m2 to construct. These houses are mostly in areas such as Kayole, and over 2 km from tarmac in major towns around Nairobi.

The breakdown is as below.

From this, we can see land cost is around 16.5 % of total housing costs. This is more or less within the international averages of 20%.

This means that in low cost housing, bank interest at 11.9% of total housing costs is what needs to be adjusted so as to reduce costs.

In middle cost housing, using the average cost of construction at kes 25,000 per m2 for a 100m2 house, the land cost is 32% of the total housing cost. This is higher than the international average of 20%.

Such areas as Kitengela, Ngong, Ruiru where a 1/8th piece of land costs 1.5m will give the scenario above.

The financial charges, with interest rate at 18% is also quite high.

Solution will be for Government to look for ways that will reduce interest rates and reduce cost of land.

For high cost housing, an abnormally huge percentage of housing costs are taken up by land. The 40% land costs are way beyond the average 20% in other parts of the world.

In high class neighborhood such as Kahawa sukari, garden estate etc, most of the housing cost is taken up by the land.

Conclusion.

Land price appreciation in Kenya on average has a rate of between 25 to 100% annually.

Last year the price of 1 acre of land in Upper Hill CBD was kes 250m.

Current asking prices for the same acre is kes 400m. This represents a 60% appreciation rate per year.

Last year a residential plot in Syokimau 1km form tarmac was going for kes 1.5m. Its currently selling for 2.5m. This represents 66% appreciation annually.

This appreciation on land price is higher than the international average of 5 to 10%.

Construction cost for a middle class building in 2008 was kes 18,000 per m2. After 5 years, it has gone to kes 25,000.

This represents 8% annual appreciation rate which is normal and in tandem with the international rates.

Clearly, Kenyan land appreciation rates have gone viral and only the Land Commission can tame this with the introduction of Idle land taxation.

Natural stone cladding in buildings

Natural stone cladding for walls ensures a building has unique aesthetic look which is easy to maintain.

Natural stone cladding can be either thinly sliced quarry stone or Mazeras slate stone which is mined from the ground in sheets.

High cost CBD Buildings.
Its quite common to see high cost high rise buildings in Nairobi CBD being clad with such.
Buidings such as Mayfair centre near Nairobi Hospital have even gone further and utilised Mazeras stone as road paving for pedestrians and cars.
mayfair centre

Disadvantages.

Building entrances.

Cladding with stone near entrances is not advisable. This is because stone tiles tend to be quite heavy and in case they are loose, can fall and cause serious harm to passers-by below. This Naivas Supermarket in Ngong town has been clad with mazeras at the busy entrance which poses danger when the stones fall to the ground.

IMG_20131013_171811

Conclusion.
Natural stone is one of the best cladding materials that can be used in buildings. It costs around kes 2,700 per m2 which is not very expensive compared to the effect that it achieves.

Lifts and Elevators in Buildings.

Lifts are used to enable transportation between vertical floor levels in a building.
There are various types such as

Escalators.
Dumb waiters.
Passenger lifts
Car/goods lift
Wheel chair stir lift

Escalators.

These are mainly used to move form a few storeys, usually 1 to 3 storey levels. Most malls in Kenya have these.

These are moving stairs. Advantages are that they are not easily filled up to capacity. They also serve as normal stairs when not working/rotating.
They should be located in an easily recognisable space e.g. next to the entrance.
Escalators cost around kes 2m per unit FOB China.

Dumb Waiters.

These are mostly seen in busy hotel kitchens. They are too small for human transport so they are used to transport smaller goods e.g. dishes , clothes for laundry etc. between 2 floor levels.

Passenger lifts.
These are used to transport people/goods through several floor level in a high rise building.
Some are panoramic, with the external side covered with see through glass.
In 1853, Elisha Otis, an American, establishes a lift making company.
In 1887, Alexander Miles, an African American, designed and patented safe lift doors.

Small residential lifts that go between 2 to 3 floor levels cost around kes 500,000 FOB China.
Large commercial lifts costs around kes 2m FOB China.

These have enabled for efficient land use in that people can work and live in buildings that have over 20 floor levels. Times tower has 38 floor levels. Access here can only be make possible through passenger lifts since its not easy to walk up the stairs in 38 floor levels.

Car lifts.

The Intercontinental hotel, Nairobi car park utilises car lifts.

Car lifts can be used to create more ground space in narrow small plots as shown above.

Car lifts move cars upwards/downwards into stacked parking slots as shown in the video below.

These car lifts enable space saving in busy cities . In Nairobi, these will slowly start being constructed once entrepreneurs comprehend the benefits of such.

Stair lifts.
These are used to enable people on wheel chairs access vertical floor levels.

The staircases within the Kenyan Supreme court which have demarcated some space and used ramps for wheeel chairs could use wheel chair stair lifts like the one below instead.
