In today’s Kenyan real estate market, a quiet but powerful industry has emerged alongside established firms and major property developers Nairobi.
It is an industry operating almost entirely outside boardrooms and professional offices, yet it is increasingly shaping how real estate in Kenya is designed, approved and built.
Behind many of the homes coming up in fast-growing estates and satellite towns is a growing network of informal house-plan sellers and online “architects” whose businesses exist mainly on Facebook and WhatsApp.
This hidden design economy is quietly reshaping the Nairobi property market and influencing how ordinary Kenyans approach home building.

Who really designs most of the houses being built today?
Walk through developing areas such as Ruiru, Kitengela, Joska, Kamulu, Juja or Ngong and a clear pattern emerges.
Many houses look strikingly similar.
The roof lines match.
The window placements repeat.
The floor layouts feel almost identical.
While large real estate developers in Kenya continue to rely on registered architectural firms for gated estates and apartments, most individual home builders now source their designs online.
For many first-time builders, the designer is no longer an office in town.
It is a phone number shared in a WhatsApp group.
The rise of Facebook house-plan sellers

A simple search for “house plans Kenya” on Facebook opens up hundreds of pages and personal profiles offering:
- three-bedroom bungalow plans
- maisonette designs
- ready-made drawings for county approval
- quick custom designs
Most posts follow the same script:
“Affordable house plans. Ready for approval. Call or WhatsApp.”
Prices range from as low as KSh 2,000 to about KSh 15,000.
In a country struggling to deliver affordable housing in Kenya, these low fees make professional design services appear unnecessary to many small builders.
WhatsApp has become the new design office
After the first message on Facebook, almost every transaction moves to WhatsApp.
This is where:
- sample drawings are shared
- room sizes are adjusted
- payments are requested
- final plans are delivered
Entire businesses now operate without physical offices, formal contracts or company registration.
For people rushing to build on newly acquired land for sale in Kenya, WhatsApp convenience feels faster and safer than engaging a professional firm.
The copied drawings economy
One of the least discussed realities in the Kenyan real estate market is how frequently house designs are copied and resold.
Many online sellers recycle drawings originally produced for:
- private homeowners
- small rental developers
- student projects
- foreign design catalogues
Minor cosmetic changes are made and the same plan is presented as a fresh design.
In some cases, the same floor plan appears on several Facebook pages, each seller claiming to be the original designer.
This silent copying economy has created a shadow market for architectural drawings.
The problem of unregistered designers

Not everyone selling plans online is an architect or registered architectural technologist.
Many sellers are:
- former drafting students
- site foremen who learned software informally
- civil engineering dropouts
- freelance technicians
They operate outside professional regulation.
For homeowners building residential property in Nairobi and surrounding counties, this creates a serious accountability gap.
If a design fault later causes structural problems, there is usually no legally traceable professional behind the drawing.

Why homeowners still prefer them
Despite the risks, demand keeps growing.
The reasons are simple.
1)Speed.
Most online sellers promise delivery within hours.
2)Cost.
For many families trying to build before prices rise again, design fees are seen as an easy place to cut.
3)Pressure to start construction.
Many sellers advertise that their drawings are “county ready”, appealing to people rushing to put up structures on plots bought through agents marketing houses for sale in Nairobi and surrounding commuter towns.
In today’s real estate investment in Kenya environment, speed often matters more than process.
County approvals and quiet shortcuts
Some plan sellers go further and claim they can “assist with approvals”.
In practice, this usually means helping clients prepare simplified drawings that only meet minimum submission requirements.
Later, many homeowners realise that:
- structural detailing is weak
- drainage and service layouts are missing
- site-specific conditions were ignored
The drawings may pass the initial desk review, but they are rarely customised to the real conditions of the land.
These shortcuts quietly undermine construction quality across the Nairobi property market.
How this affects the wider real estate sector

This informal design economy now explains:
- why many estates look visually identical
- why similar construction mistakes repeat across different neighbourhoods
- why poorly planned rental layouts keep spreading
While large developers continue to dominate headlines, the majority of housing units added every year are still self-built.
That means Facebook and WhatsApp designers now influence how ordinary families invest, build and live far more than many formal industry players.
They are quietly shaping the direction of real estate in Kenya from the bottom up.
A new kind of real estate middleman
House-plan sellers now sit between the homeowner and the fundi on site.
They influence:
- how families use space
- how land is subdivided
- how estates visually evolve
Yet they are absent from most conversations involving property developers Nairobi, planners and professional associations.
A parallel design economy has formed alongside formal real estate practice.
What this means for future housing in Kenya
As demand for housing continues to rise, this informal system is unlikely to disappear.
Unless professional services become more affordable and accessible to ordinary builders, Facebook and WhatsApp will remain the first stop for many Kenyans planning to build.
For the wider Kenyan real estate market, the real story is not only about prices, mortgages or developer activity.
It is also about who quietly controls the very first and most powerful decision in construction- the design of the home.
