The Team Behind Every Project
An In-House Team You Will Actually Meet
Your project is not subcontracted. From the first site visit to the final handover, the same Magnum people are on the ground.
Why Trust Magnum?
Four guarantees that turn a renovation into a defined project.
Full home renovations carry the biggest risks of any building project — subcontractor chaos, mid-project price hikes, permit delays, dubious workmanship. Here is how we close every one of them.
In-House Team — No Subcontractors
Twenty-two craftsmen and project managers on Magnum's payroll. The same people who quote your project are the ones on site every day.
Fixed-Price Contract
After the 3D render and quantity survey, we lock the price. No hidden costs, no mid-project surprises — what you sign is what you pay.
Permits & Licences Included
We handle the bureaucracy: town hall licence, technical project, structural sign-off and energy certificate. You sign once, we do the rest.
10-Year Structural Warranty
Beyond the legal minimum: we back every structural element, waterproofing layer and installation for ten full years after handover.
How It Works
From First Visit to Finished Home
FREE SITE VISIT
We come to you
We measure, listen to how you live and discuss layout options. 60 minutes, no cost, no obligation.
SHOWROOM VISIT
See and touch every material
You visit our Marbella showroom and physically handle every marble, wood, tile, kitchen cabinet, fixture and finish before they go anywhere near your 3D render. Decisions made on real materials, not screen samples.
3D RENDER
Approve before we build
Our in-house architects and interior designers produce a photorealistic 3D render of every room — using exactly the materials you selected in the showroom. You approve every detail before a single wall is touched.
FIXED-PRICE CONTRACT
No surprises
Line-by-line quote, locked start date, locked end date. Permits and licences fees included. Written into the contract.
ON-SITE EXECUTION
8-20 weeks typical
Demolition, structural work, plumbing, electrical, tiling, joinery, paint — all run by your dedicated site manager. Weekly progress photos.
HANDOVER & WARRANTY
10-year cover
Snag walk-through, full documentation pack and 10-year structural warranty. Manufacturer warranties on every appliance, registered on your behalf.
Client Voice
“We renovated our villa from London. Magnum delivered the handover four weeks early and exactly to the fixed price we signed eight months earlier. Not a single surprise invoice — and the result matches the 3D render to the millimetre.”
