A refurbishment in Victoria is defined less by structure than by tenure. Most of the stock here is leasehold flats — purpose-built mansion blocks, apartments in managed buildings and mixed-use units above commercial floors — and the lease sets what a leaseholder may and may not do inside the demise. It commonly reserves the structure, the external envelope and often internal load-bearing walls to the freeholder, and requires a formal Licence to Alter before works of any scale. So the first task is not a design one: it is reading the lease and establishing what is owned, what is retained and which consents the freeholder and managing agent will require before anyone lifts a floorboard. The demise itself is often narrower than owners expect — ceilings, floor screeds and the party structures between flats are frequently outside it — and that boundary decides which parts of the flat can be altered freely and which need the freeholder at the table from the start.
The Licence to Alter is usually the critical-path item. Freeholders and their managing agents grant it on their own terms and their own timetable, and they typically want a complete package before they engage: general arrangement drawings, a specification, structural information where any wall is affected, and a method statement covering how the flat will be stripped out and rebuilt without damaging the building or disturbing neighbours. Their surveyor may review and charge for the review, and the licence is often conditioned — restricting hours, protecting common parts, requiring insurances and sometimes a deposit against damage to the building. Delays here are usually caused by an incomplete submission that the surveyor returns for missing structural or acoustic detail, not by the freeholder being obstructive. We prepare that package to the standard a freeholder expects, so the consent is secured rather than stalled, and we sequence it ahead of any commitment on site.
Sound is the constraint that shapes the interior. In a mansion block the flats above and below are someone's home, and a refurbishment that moves rooms around, lays hard flooring or relocates a bathroom can transform how noise travels between demises. Many leases carry an express covenant requiring carpet or an equivalent acoustic finish across habitable floors, and the sensible standard is to design a floating or resiliently isolated floor build-up that controls both impact and airborne sound to the flat below. We set the acoustic strategy at the outset — floor build-ups, wall linings around any relocated wet room, and isolation at service penetrations — because it is far cheaper to design in than to retrofit after a complaint. Building regulations set a sound-insulation standard between separate dwellings, and a freeholder will often want to see how a hard finish meets both the lease covenant and that standard before the licence is granted, so the two requirements are resolved together on the drawings.
Services are where a flat refurbishment quietly gets difficult. Soil and waste from kitchens and bathrooms drain to a shared stack, usually in a communal riser, and there is only so far a new bathroom or utility can move before the fall to that stack becomes unworkable or a pump is needed. Incoming water, heating and any mechanical ventilation run within the same tight envelope, and works to the riser or to shared services almost always need the freeholder's consent and coordinated shutdowns arranged through the building manager. We survey the existing service routes early and plan the layout around the riser and the stack, rather than drawing an ideal plan that the drainage cannot actually serve. In a mixed-use building with commercial space below, extract and ventilation routing is tighter still, because ducts and flues cannot simply be pushed through a shared ceiling void without the freeholder's agreement and a route that respects the units around them.
Getting a refurbishment in and out of a managed building is a logistics problem as much as a construction one. Central Victoria buildings run their own rules: lift bookings for materials and waste, protection of lobbies, stairs and finishes in the common parts, restricted working hours, noise limits and often a requirement for method statements and consultant sign-off before access is granted. A strip-out generates a great deal of debris that has to leave through shared circulation, and deliveries compete with a busy central location for kerb space. We build these constraints into the programme and the tender information so the contractor prices the real conditions, and the building manager sees a scheme that respects the other residents. A contractor who has not been told about a single-lift building, a 9-to-5 working window or a ban on skips at the kerb will either price the risk high or discover it mid-job, and both outcomes cost the client, so the conditions belong in the documents from the start.
From there the route is coordinated but internal. We survey the flat, confirm the lease position and the heritage and listing status for the exact address, then develop a reconfiguration that works within the structure and the services actually present. We prepare the Licence to Alter package for the freeholder, and once the interior alterations are settled we produce the building regulations drawings — covering structure where any wall is opened up, fire safety, ventilation, drainage and the acoustic separation to neighbours — for construction. Where a party structure between flats is affected, the Party Wall etc. Act 1996 can apply between leaseholders, so we identify notifiable neighbours early rather than late. Throughout, we keep the freeholder, the managing agent and building control aligned so the interior that is drawn is the interior that can actually be consented, tendered and built without a late surprise unpicking the programme.
