The Sculpted Abode, Part 5: Dubai Villa Renovation Week 2 - *MEP, HVAC, and Critical Sequencing
After the raw emptiness of Week 1, there was a noticeable shift on site — the sounds changed from walls coming down to walls going up. Instead of rubble being carried out, materials were being brought in. It finally felt like the house was on its way back to becoming a home.
This post dives into one of the least glamorous yet most critical phases of any renovation: the installation of MEP and HVAC — the hidden systems that decide whether your home functions flawlessly or frustrates you for years to come.

From Shell to Structure
Week 1 was demolition shock. Week 2 marked a transition from an empty shell to a home in progress: walls rising, systems being installed, and the sequence of works kicking into high gear. It was a fast-paced shift from dismantling to rebuilding, demanding accuracy, coordination, and decisive calls at every step.
The contracting team worked at full speed. New block walls went up, locking in the reconfigured layouts we had finalized on plans beforehand. Balcony and rooftop tiling — which had started in Week 1 — was completed and sealed, giving the house its first layer of protection.
What are MEP and HVAC?
MEP stands for mechanical, electrical, and plumbing — the water supply lines, drainage, and wiring that make a house livable. HVAC — heating, ventilation, and air conditioning — are the systems that regulate air and temperature. In Dubai, that mostly means cooling and airflow, but the principles are universal.
Bathrooms evolved from bare concrete to prepared shells, complete with niches. The main contractor’s team carried out all MEP works, which stands for mechanical, electrical, and plumbing. In plain terms: the water supply lines, drainage routes, wiring, and the exact placement of every fixture. It’s the web of hidden systems that make a home function. At this point, the concealed components of our Ramon Soler | Amisa bathroom fixtures were installed: wall-mounted taps, shower mixers, and freestanding tub fillers, all set with millimeter precision before the tiles could go in.
Meanwhile, the HVAC specialist, responsible for heating, ventilation, and air conditioning, continued with ductwork, final layouts, and fitting some beautifully curved bespoke AC grilles we designed for key spaces. In Dubai, HVAC is almost entirely about cooling and air movement, but the accuracy matters everywhere: these systems are the lungs of the house. Once ceilings are closed and walls are finished, there’s no turning back.
Windows, measured in Week 1 and fabricated within ten days thanks to early booking, hit a milestone: the largest panels were installed, sealing the house.
Why This Stage Can Make or Break a Renovation
Even with years of experience managing renovations for clients, being both designer and homeowner changes how I feel at this stage. I don’t just make level-headed decisions; I live through the emotions. We’re all aware of the dust, the noise, the mounting costs, and the fact that the work feels invisible compared to the “beautiful” stages of construction that are yet to come.
Developer drawings rarely match reality. In Week 1, we discovered that some pillars, shafts, and pipework were not where the original plans showed them. Our design team adjusted the drawings; the contracting team adapted the scope of MEP and HVAC works changes immediately to match the real site conditions.
At this point, many homeowners take one of three paths:
Pause the project to obtain detailed cost breakdowns, losing valuable time in negotiations.
Go back and forth with the designer to avoid additional spending while still keeping the original design, yet some changes are simply unavoidable if the build is to work.
Push the contractor to absorb costs because “it’s a big project,” which sets the wrong tone early on. You cannot keep squeezing the very people you expect to deliver their best work.
For my home renovation, The Sculpted Abode, I asked the construction team to press on with all necessary works and charge according to the agreed quotation rates. Momentum mattered more than avoiding a modest cost increase. Time and again, I’ve seen hesitation cost far more in the long run. The extra months of rent or mortgage payments often outweigh the additional construction costs.
A Parallel from The Edge of Calm
We saw the importance of this stage on The Edge of Calm, a complete Dubai Hills villa renovation for a third-time client. The works included three extensions, major MEP changes, a new HVAC system, splitting a Jack-and-Jill bathroom into two, and relocating the kitchen entirely.
The project took four months — not because of inefficiency, but because the community restricted noisy works to just a few hours each day. In another neighborhood, where construction can run from 7 a.m. to 5 p.m., the same scope would have wrapped up much faster. It’s a detail many homeowners overlook: community regulations often shape renovation timelines as much as contractors or design changes do.
Why MEP & HVAC Are the Foundations
MEP and HVAC aren’t glamorous, but they are the foundation on which everything else rests. If either slows down, the entire build slows down. I’ve seen projects where air-conditioning or electrical works dragged on for months due to indecision, looking for the cheapest (often subpar) option on the market, knocking every trade off schedule and racking up unnecessary costs.
This is where project management is critical, whether led by the designer, the contractor, or ideally both in sync. The teams must move together, keep sequencing tight, and trust each other’s process.
Do’s & Don’ts at This Stage
Do:
Approve essential changes promptly, especially for MEP/HVAC adjustments right after demolition.
Maintain open communication between the designer, contractor, and suppliers.
Secure long-lead items like windows and fixtures from abroad early.
Don’t:
Delay decisions while still paying for a home you can’t use.
Expect contractors to absorb the cost of works outside of the original scope.
Bring in outside trades without integrating them fully into the programme and without a proven track record of quality standards.
Respecting the Process
By the end of Week 2, the house was no longer a hollow shell. Walls were in place, external areas were sealed, and the hidden systems that make the home function were being locked in. This is the point where trust between every party matters most. When the designer and contractor lead in sync, decisions are made quickly, and sequencing stays tight. When momentum is shared, everyone’s investment — financial, emotional, and creative — is protected.
And with each day, you begin to feel it: the dust settles a little quicker, the shapes become clearer, and the vision starts to live beyond the drawings. You can already picture the first moments in the finished space, and that anticipation keeps the entire team pushing forward.
Looking Ahead to Week 3
With MEP and electrical works in the kitchen and bathrooms wrapping up, the focus shifts to spaces that will soon be the heart of our daily life. The kitchen, still being built off-site, is taking shape. Next week, I’ll share the 3D rendering and design thinking behind it: how we planned the flow for family life, the balance between function and beauty, and how one extraordinary slab of Italian marble inspired the entire palette. Timeless white base, veined with warm beige, sage green, and the occasional brush of deep purple. The kind of stone that doesn’t just sit in a room; it sets the tone.
This is the stage where ideas step out of drawings and into reality.
Experience the process. Watch how a vision becomes a home, week by week.
