Transform your existing home or office. We handle everything from a bathroom upgrade to a full house refurbishment — with the same fixed-price contract, daily updates and 6-month warranty as our new builds.
Most renovation projects in Ghana go over budget and take twice as long as promised. At Cornerstone Build Ghana, we fix this with a written scope of work, a fixed price, and a project timeline agreed before we start.
Whether you want to modernise an old property, renovate for rental income, or fit out a new office space — we bring the same professionalism to renovation as we do to new construction.
From a single room to an entire property — we scope it, price it and deliver it.
New tiling, vanities, cabinetry, plumbing and electrical. We transform tired bathrooms and kitchens in 1–3 weeks.
Complete refurbishment of older properties. New plastering, wiring, plumbing, roofing, tiling and painting.
Partitioning, suspended ceilings, aircon installation, data cabling, new flooring and painting for office spaces.
Affordable upgrades that maximise your rental yield. We know what tenants in Accra look for.
Interior and exterior painting, skim coating and external rendering to refresh and weatherproof your property.
Re-wiring, new circuit boards, plumbing re-runs, borehole pump installation and solar panel integration.
Renovation costs vary widely depending on what's being done. A bathroom renovation typically runs GHS 8,000–25,000. A full house renovation can range from GHS 50,000 to several hundred thousand depending on size and finish. We always provide a detailed itemised quote after assessing your property — so there are no surprises.
For partial renovations (one room at a time), yes — we can work room by room to minimise disruption. For full house renovations, we recommend vacating if possible to speed up the project and protect your belongings.
Once we have a signed contract and mobilisation payment, we can typically start within 1–2 weeks depending on our current schedule. We'll give you a confirmed start date when you book.
Any additional work beyond the original scope is handled via a written Change Order — a simple document listing the extra work and its cost, signed by both parties before we proceed. No verbal extras, ever.
Renovations range from a single-room refresh to a full structural overhaul. Understanding your scope upfront is the most important thing you can do to protect your budget.
Repainting, retiling, replacement of fittings and finishes. No structural changes — fastest and most budget-friendly renovation type. Usually 2–6 weeks depending on scope.
Full wet room overhaul — new tiling, plumbing, fittings, and waterproofing. These are the most common renovation requests we receive. Fixed-price quotes on a room-by-room basis.
Complete internal refurbishment — new ceilings, flooring, electrical upgrade, plumbing replacement, and finishes throughout. Common for older properties or diaspora handover-ready upgrades.
Knocking down or adding internal walls, adding a storey, or reinforcing a structure. Requires an architect and structural engineer — we coordinate the full team.
Adding rooms, a boys' quarters, or extending the footprint. Requires a building permit amendment in most cases. We handle the permit process as part of the project.
Transforming a shell or raw space into a functioning office, retail unit, or hospitality venue. Fast-track programme options available.

Internal cosmetic renovations (painting, tiling, replacing fittings) do not require a permit. Structural changes, extensions, or work that alters the building envelope require a permit amendment from your district assembly. If in doubt, check with your local Physical Planning Department before starting.
A full interior renovation of a standard 3-bedroom house in Accra takes 2–4 months with a dedicated renovation team. The timeline depends on scope — a bathroom-only renovation takes 2–3 weeks; a kitchen renovation takes 3–5 weeks; a full interior overhaul runs 8–16 weeks.
Get a written, itemised, fixed-price contract before any work starts. Tie payments to verified milestones — never pay more than 30% upfront. Retain 10% until snagging is complete and you are satisfied with the finished work.
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.
