Too many Ghanaians have been burned by contractors who disappear, change the price or do work that falls apart. Cornerstone Build Ghana was built to change that — with systems, standards and accountability that the industry rarely offers.
Ghana's construction industry has a trust problem. Clients sign informal agreements. Contractors change prices. Work is done without permits or warranties. Good people lose their savings building homes that take years longer than promised.
Kwaku founded Cornerstone Build Ghana with one mission: to deliver construction the way it should be done. Fixed prices. Written contracts. Daily communication. A real warranty. Professional documentation on every job — regardless of size.
We borrowed the best practices from the US and UK construction markets and adapted them for Ghana. The result is a construction company that actually operates the way a construction company should.
Today, Cornerstone Build Ghana has completed over 150 projects across Greater Accra — homes, offices, renovations, civil works and repairs. Every single one on a fixed-price contract with a 6-month warranty.
Start Your ProjectYou should always know what you're paying for, what's been done and what's coming next. Our fixed-price quotes, written contracts and daily updates exist because transparency is not optional — it's the foundation of trust.
When something goes wrong on a project — and in construction, sometimes things do — we own it. Our 6-month warranty is our promise that we stand behind our work after handover. No excuses.
We source locally, hire locally and build specifically for Ghana's climate and conditions. We're not applying a foreign template — we're building a Ghanaian construction company that happens to operate at international standards.
"Cornerstone is the first contractor in Ghana who gave me a contract before starting work. That alone told me everything. The build was on time, on budget, and the quality is excellent."
"I was building from London. The daily photos on WhatsApp meant I could sleep at night knowing what was happening. I watched every stage of my house being built from 5,000 miles away."
"I've tried three contractors before. Only Cornerstone delivered what they promised at the price they quoted. I've already referred four people to Kwaku. I wouldn't use anyone else."
Cornerstone Build Ghana is registered and classified under Ghana's contractor registration scheme. We can provide our classification certificate on request — and you should always ask any contractor you are considering for theirs.
Every project is governed by a written, signed, fixed-price contract. Not a verbal quote. Not a WhatsApp message. A legal document that specifies what we build, for what price, by what date, and what warranty applies.
Our quotes list every material and every labour item separately. You can check each line against market prices — and we encourage you to. Transparency is how we earn trust; it is not a risk to us.
Every Cornerstone client receives daily photographs of site progress via WhatsApp — sent by your project manager from the site. Diaspora clients in the UK, US, Canada and beyond use this to watch their home being built in real time.
Every completed Cornerstone project carries a 6-month workmanship warranty from handover date. Any defect in our workmanship — cracked plaster, leaking roof joint, faulty fitting — is corrected at our cost within the warranty period.
We have completed over 100 residential, commercial, and civil projects across Greater Accra. We can provide reference clients in your area — people who have built with us and will tell you, in their own words, what the experience was like.
These are the checks we recommend for any contractor — including us. If a contractor objects to any of these, that is the answer.
Ghana's contractor registration system classifies contractors by capacity. An unregistered or low-classification contractor on a large project is a risk — both financially and structurally.
Any contractor who refuses to provide a breakdown of materials and labour has something to hide. A lump-sum quote with no detail is a blank cheque.
Ask specifically: did the price change from the quote? Were you kept informed throughout? Were defects fixed after handover? A good contractor will happily provide references.
A legitimate contractor has supplier relationships that allow them to mobilise without a full advance payment. Any demand for 50%+ upfront before work begins is a serious warning sign.
The contract should specify: what is being built (drawings attached), for what fixed price, by what completion date, with what payment schedule, and what warranty. If any of those elements are missing, do not sign.
Make sure you have the right information before committing to any construction project in Ghana. These are our most-read guides:
We visit your plot at no charge and no obligation. During the site visit we assess soil conditions (critical for foundation type and cost), confirm plot dimensions, evaluate access for materials delivery, and identify any site-specific constraints that will affect the build. This visit is what makes our quote accurate rather than estimated — and it costs you nothing.
Your quote lists every material item (quantity and unit cost), every labour operation, supervision, professional fees, permit fees, and contingency — separately. You can compare every line against current market prices. We do not use lump-sum estimates. Transparency is how we earn trust and verify value simultaneously.
Once you are ready to proceed, we sign a fixed-price construction contract before any money changes hands. The contract specifies: the complete scope of work; the fixed contract sum; the payment schedule (tied to milestones, not dates); the completion timeline; and a 6-month workmanship warranty. The price in the contract is the price you pay — it cannot be changed without a signed change order agreed by both parties.
Your crew is assigned exclusively to your project — not shared across four or five other sites. Each day, your dedicated project manager sends WhatsApp site photographs from the build. This is particularly important for diaspora clients who cannot visit the site regularly — you see exactly what is being built, at what stage, in real time. If any issue arises on site, you hear from us before it becomes a problem.
Payments are released against verified construction milestones, not against calendar dates. Our standard residential schedule: 30% on contract signing and site mobilisation; 40% on completion of structural works (foundation, walling, slab, and roofing); 30% on practical completion and handover. You do not pay for the next phase until the previous phase is confirmed complete — protecting your money throughout the project.
Every Cornerstone project carries a 6-month written workmanship warranty from handover date. Any defect in our workmanship — cracked plaster, roof leak at a junction we installed, failing tile adhesion, faulty fitting — is corrected at our cost within the warranty period. We provide this warranty in writing because we are confident in our work. We can also provide references from clients who have tested the warranty and confirm it was honoured without dispute.
Free site visit. Fixed-price quote in 48 hours. 6-month warranty included. 150+ satisfied clients. Your project deserves the Cornerstone standard.
