A concept design and feasibility study in Kenya is the smartest investment you can make before committing to any construction project. Cadreatech answers the three questions every developer needs first — what can you build on your land, what will it cost, and is it worth building at all.
Start Your Feasibility Study →Why it matters
What is a Concept Design and Feasibility Study in Kenya — and why do you need one?
A concept design and feasibility study in Kenya answers two fundamental questions before any money is spent on full drawings: what can we build here? and is it worth building? Together, they protect your investment by confirming both the regulatory and financial viability of your project at the earliest possible stage.
In Kenya, many developers and landowners skip this stage entirely. As a result, they commission detailed designs only to discover mid-process that their plot does not support the intended use, that zoning restrictions cap the building height, or that construction costs far exceed their budget. Consequently, they lose time, money, and momentum — problems that a proper concept design and feasibility study would have prevented from the start.
Feasibility study vs. concept design — what is the difference?
The two services are closely linked but serve different purposes. A feasibility study evaluates whether your project is viable — assessing land, regulations, costs, and returns. A concept design, on the other hand, translates your brief into spatial ideas: bubble diagrams, massing studies, block plans, and preliminary layouts that show what the building could look like and how it could work.
Together, they form the foundation of every well-planned construction project. Cadreatech delivers both as an integrated service, so your design vision and your financial reality are aligned from day one.
The full picture
What Cadreatech analyses in your concept design and feasibility study
A credible feasibility study in Kenya covers far more than a quick look at a plot. Cadreatech’s process examines every factor that affects what can be built, how much it will cost, and whether the project stacks up financially.
We assess plot size, shape, topography, orientation, access, and surrounding context. We also note any easements, wayleaves, or encumbrances on the title that could affect development.
We confirm the plot’s zoning category — residential, commercial, mixed-use, or institutional — and identify the permitted uses, setback requirements, and any change-of-user conditions under the PLUPA Act 2019.
We calculate the maximum allowable floor area based on the plot’s Floor Area Ratio (FAR) and Building Coverage Ratio (BCR) — the two key metrics that determine how much you can build on your land.
Under Kenya’s Physical and Land Use Planning (Building) Regulations 2021, county governments prescribe maximum building heights for each zone. We establish this limit early so your concept design stays within it.
We calculate the minimum parking provision required by the county for your building type and size — a factor that significantly affects the footprint and layout of any commercial or residential development.
We identify whether your project requires an Environmental Impact Assessment (EIA) from NEMA, and flag any environmental sensitivities — drainage, flooding risk, tree preservation — that affect the design.
Working with our in-house quantity surveyors, we produce an order-of-magnitude cost estimate based on the proposed development scope, current Kenyan construction rates, and site-specific factors.
We outline a realistic project timeline — from feasibility through design, approval, and construction — so you can plan financing, procurement, and occupancy with accurate expectations.
The study concludes with a clear recommendation: proceed, modify, or reconsider. If proceeding, we define the optimal development scope and outline the path to full design and county approval.
Bringing ideas to life
What concept design involves in a feasibility study — and what you receive
Concept design is the creative stage where your brief becomes a spatial reality. Unlike construction drawings, it produces the thinking and visual tools that guide everything that follows. As a result, your full architectural design is built on a clear, tested idea rather than a vague intention.
Bubble diagrams and spatial relationships
Before any floor plan is drawn, Cadreatech’s architects produce bubble diagrams — schematic drawings that map the relationships between spaces. For example, how should the reception relate to the offices? Where should the kitchen sit relative to the dining area? These diagrams resolve functional logic before dimensions are committed to paper.
Massing studies
A massing study tests how the building sits on the plot in three dimensions. It examines building height, footprint, orientation, and shadow — helping clients and planners understand the proposed development in its physical context. Massing studies are particularly useful for multi-storey projects, corner plots, and sloped sites.
Block plans and preliminary layouts
Block plans translate the massing study into a scaled floor plan. They show room arrangements, circulation routes, and key dimensions — without the detail of full working drawings. These layouts are used to test design options, brief structural and MEP consultants, and give clients a clear picture of the proposed building before full design fees are committed.
Design options and client review
Cadreatech typically presents two or three design options at concept stage. Each option explores a different approach to the brief — varying layout, orientation, or massing. After client review and discussion, we refine the preferred option into a single concept proposal that forms the basis for the full architectural design.
How we work
Our concept design and feasibility study process — step by step
Our process is structured to move quickly, involve the client at every key decision point, and produce a clear output that feeds directly into the next phase of the project.
Client brief and site visit
We begin by understanding your goals — the intended use, the target budget, the timeline, and any constraints or preferences you have. After that, our architect visits the site to assess conditions on the ground: topography, access, neighbouring structures, and any obvious opportunities or risks.
Desk study and regulatory research
We research the plot’s zoning classification, applicable setbacks, FAR, building height limits, and parking requirements from the relevant county planning records. We also check for any NEMA obligations, wayleaves, or planning restrictions that apply to the site.
This step often surfaces critical constraints early — before any design work begins — saving significant time and cost downstream.
Feasibility analysis and cost benchmarking
Based on the regulatory findings and the client’s brief, we establish the maximum buildable area and the likely construction cost range. Our quantity surveying team provides preliminary cost benchmarks using current Kenyan construction rates for the relevant building type and specification level.
Concept design development
With the feasibility parameters defined, our architects develop concept design options. We explore bubble diagrams, massing studies, and block plans — typically producing two or three options for client review.
Each option is tested against the regulatory limits established in step two, so every concept we present is actually buildable under the applicable zoning rules.
Client review and design selection
In a structured review session, our team presents the concept options and explains the rationale behind each one. The trade-offs are laid out clearly, along with our recommendation. Together, we then select and refine the preferred concept — incorporating your feedback before moving forward.
Feasibility report and concept package
The engagement concludes with a written feasibility report and a concept design package. The report covers site analysis, regulatory findings, cost benchmarks, programme, and a clear development recommendation.
This package then feeds directly into Cadreatech’s full architectural design service — or serves as a standalone document for financing, investor briefing, or land purchase decisions.
Is this right for you?
When should you commission a concept design and feasibility study in Kenya?
Not every project needs the same level of feasibility work. However, certain situations make a proper concept design and feasibility study essential rather than optional.
🏗️ Before purchasing land
A feasibility study before land purchase confirms what you can actually build on a plot — and whether the asking price reflects the development potential. Many buyers overpay for land that turns out to have restrictive zoning, poor access, or insufficient plot ratios for their intended use.
🏢 Before committing to a development type
If you are deciding between, say, a residential development and a commercial one on the same plot, feasibility analysis quantifies the financial and regulatory implications of each option — giving you the data to make a well-informed decision rather than an intuitive one.
💰 Before approaching a financier or SACCO
Banks, SACCOs, and real estate investors increasingly require a feasibility study as part of a project finance application. A credible study prepared by a registered architectural firm carries significantly more weight than a spreadsheet or a verbal estimate.
🔄 Before redeveloping an existing property
Redevelopment projects often involve change-of-user applications, demolition, or densification. A feasibility study confirms the regulatory pathway, identifies any heritage or environmental constraints, and ensures the new development is viable under current county zoning rules.
🌍 For diaspora and remote investors
If you are investing in Kenya from abroad, a concept design and feasibility study gives you a reliable, documented picture of what your land can support — without having to rely on local intermediaries or unverified verbal assurances. Cadreatech works with diaspora clients across the UK, USA, Canada, and the Gulf. Learn more about our residential design services.
📐 For complex or large-scale projects
Multi-storey buildings, mixed-use developments, estate layouts, and institutional projects all carry greater regulatory complexity and higher financial stakes. For these projects, thorough concept design and feasibility work is not a luxury — it is a prerequisite for responsible development.

The bigger picture
How your concept design and feasibility study connects to the rest of your project
The concept design and feasibility study is not a standalone exercise. Instead, it is the foundation on which the entire project is built. Here is how it connects to every subsequent stage:
Full architectural design
The approved concept design feeds directly into Cadreatech’s full architectural design service. The spatial logic, building form, and regulatory parameters established at concept stage guide the development of detailed working drawings — ensuring the design evolves consistently rather than starting from scratch.
Structural engineering
The preliminary massing and floor plans from concept stage allow our structural engineers to begin scoping the foundation and superstructure system early. In turn, this early coordination prevents conflicts between architectural and structural requirements later in the design process.
Quantity surveying and cost management
The preliminary cost estimate produced at feasibility stage evolves into a detailed Bills of Quantities as the design develops. As a result, our quantity surveying team maintains cost visibility from feasibility through tender — so there are no budget surprises at construction stage.
County approval and regulatory compliance
Because the concept design is developed within the regulatory envelope established by the feasibility study, it enters the county approval process with a strong chance of first-pass success. In addition, designs built on confirmed zoning parameters do not require the retrospective corrections that frequently delay approval submissions.
Geotechnical investigation
The feasibility stage is also the right time to commission a geotechnical investigation. Soil conditions directly affect foundation type, depth, and cost — all of which influence the overall feasibility of the project. Therefore, Cadreatech coordinates geotechnical and architectural work in parallel to avoid programme delays.
Common questions
Frequently asked questions about concept design and feasibility studies
How long does a concept design and feasibility study take?
For a straightforward residential or small commercial project, Cadreatech typically completes a concept design and feasibility study within two to four weeks. Larger or more complex projects — mixed-use developments, multi-storey buildings, or sites with significant regulatory complexity — may take four to eight weeks.
The timeline depends on the speed of client feedback at review stages and the complexity of the regulatory research required for the specific county and zone.
What is the difference between a feasibility study and a full architectural design?
A feasibility study tests whether a project is viable and establishes the parameters for design. A full architectural design develops the approved concept into a complete set of drawings suitable for county approval and construction. The feasibility study comes first — it informs and de-risks the full design process.
Skipping the feasibility stage and going directly to full design is a common and costly mistake. It often results in expensive revisions when regulatory constraints or cost realities surface later.
Can a feasibility study be used to secure financing?
Yes. A well-prepared feasibility study — produced by a registered BORAQS architectural firm and including a preliminary cost estimate and development recommendation — is a standard supporting document for bank and SACCO financing applications in Kenya.
Cadreatech’s feasibility reports are structured to meet the information requirements of most financial institutions. We can tailor the format and content to suit your specific lender’s requirements on request.
What is a plot ratio and why does it matter?
The plot ratio — also called the Floor Area Ratio (FAR) — is the ratio of total building floor area to plot area. For example, a FAR of 2.0 on a 500 m² plot allows a maximum of 1,000 m² of total floor area across all levels.
The FAR is set by county zoning regulations and determines how large a building can be on a given plot. It is one of the most important figures in any feasibility study, because it directly defines the maximum developable area — and therefore the maximum revenue potential of the site.
Does Cadreatech handle feasibility studies outside Nairobi?
Yes. Cadreatech conducts concept design and feasibility studies across all 47 counties. Our team researches county-specific zoning regulations, setback requirements, and building height limits for each project — regardless of location.
We have completed projects in Nairobi, Kiambu, Nakuru, Kisumu, Mombasa, Machakos, Uasin Gishu, and beyond. Remote and diaspora clients are welcome — we can manage the entire feasibility process with minimal physical presence required from the client.
What happens after the feasibility study is complete?
If the study confirms the project is viable, Cadreatech moves into the full architectural design phase. The concept design package produced during feasibility becomes the foundation for detailed working drawings, structural design, MEP engineering, and ultimately the county approval submission.
If the study identifies constraints that make the original brief unviable, we work with the client to modify the brief — adjusting the scale, use, or approach — before committing to full design fees.
