An apartment renovation begins long before the first demolition work. Decisions about the layout, electrical and plumbing systems, materials and budget determine how the work will progress and how many changes will be needed along the way.
Problems often arise when construction moves ahead of planning. Sockets are installed before the kitchen layout is finalised. Flooring is ordered before finished floor levels have been coordinated. Contractors are ready to continue, but the materials they need have not yet arrived.

Good preparation brings these decisions together in a workable sequence. In this guide, we explain how to define the scope of your renovation, allocate your budget and organise the work so that each stage builds on decisions already made.
1. Decide what you want to change
Before requesting quotes, write down what is not working in your current home. Insufficient storage, an awkward kitchen or the lack of a workspace are more useful starting points than a general wish for a “modern interior”.
Consider each room in relation to your daily routine:
- How do you use it now, and how would you like to use it after the renovation?
- Which furniture and appliances will you keep?
- What makes movement or maintenance difficult?
- Do you need more storage, better lighting or additional work surfaces?
- Do you expect changes in your household over the next few years?
Then divide the tasks into three groups: essential, desirable and those that can wait until later.
Repairing a leak and replacing worn-out wiring have different priorities from adding a decorative wall finish. This distinction helps protect your essential needs if the budget proves tighter than expected.
A cosmetic update, partial renovation or full renovation?
A cosmetic update usually focuses on visible finishes: painting, selected flooring, light fittings and furniture.
A partial renovation may cover a kitchen, bathroom or several rooms. However, it can also affect adjacent areas because of shared services, flooring or the junctions between existing and new work.
A full renovation involves more extensive work, which may include changes to the layout, electrical and plumbing systems, surface preparation and complete furnishing.
Simply telling a contractor that you want to “renovate a one-bedroom apartment” is not enough. You need a list of the specific works you want them to quote for.
2. Assess the apartment’s condition
The initial inspection should establish both the dimensions and the conditions in which the work will take place. What you can see does not always reveal what lies beneath the flooring or behind wall finishes.
Pay attention to:
- signs of damp, leaks and condensation;
- cracks and uneven areas on walls and ceilings;
- the condition of electrical wiring and plumbing;
- windows, seals and signs of water ingress;
- ventilation in the kitchen and bathrooms;
- differences in floor levels;
- access to pipe risers, shut-off valves and components that require servicing.
If you are unsure what is causing a problem, consult the relevant specialist. Fresh paint will not resolve an active leak, and furniture should not obstruct areas that need maintenance access.
If you are considering removing walls, relocating bathrooms or altering shared building services, establish the technical feasibility and any necessary approvals beforehand. These decisions should not be left to the construction team on site.
Prepare a measured survey and photographic record
Measure the rooms, openings, heights and positions of existing service connections. Record columns, recesses, beams and other features that could affect the furniture layout.
Photos taken before the renovation are useful for comparison and communication. During the work, photograph concealed services before they are covered. These images can help with later installation or maintenance, but they do not replace technical drawings.
3. Finalise the layout before construction begins
Changing completed work is one of the most expensive causes of delay. This is why the layout and the main furniture positions should be established before new electrical and plumbing systems are installed.
You need to know where the following will be located:
- kitchen cabinets and appliances;
- bathroom fixtures;
- beds and bedside tables;
- wardrobes and custom furniture;
- the television and workspaces;
- general and supplementary lighting.
For example, a socket behind a wardrobe may be practically unusable. The connection for the extractor hood depends on the kitchen design. Light fittings need to be positioned in relation to the dining table, worktop and other furniture.
Interior planning at this stage helps coordinate the space, furniture and technical requirements. The level of detail needed depends on the scope of the renovation, but contractors should have sufficiently clear instructions before work begins.
Which decisions can wait?
Textiles, some freestanding furniture and decorative accessories can often be selected later.
Decisions that determine service connections, installation dimensions, floor levels or built-in components need to be made earlier. These include shower systems, concealed taps, kitchen appliances, lighting profiles and certain types of doors.
4. Break the budget down into categories
A total renovation budget provides a useful spending limit, but it does not show how the money will be used. A workable budget divides costs into categories.
Include:
- inspections, measured surveys and design;
- removal work, waste disposal and preparation;
- electrical and plumbing work;
- substrate preparation, screeds, skim coats and waterproofing;
- flooring, wall finishes and painting;
- doors and windows, where included in the scope;
- bathroom fixtures;
- lighting;
- the kitchen and other furniture;
- appliances;
- transport, carrying items into the apartment and installation;
- cleaning and final corrections.
This makes it easier to see where adjustments are possible and where reducing expenditure would affect quality or functionality.
Allow a contingency for unknown work
In an older home, some requirements become apparent only after existing finishes and fixtures have been removed. Damaged pipes, an unstable substrate or areas requiring additional preparation may be uncovered.
Set aside a separate contingency according to the apartment’s condition and the level of uncertainty. Do not allocate it to decorative purchases in advance.
There is no single contingency amount suitable for every renovation. A home with well-documented services and a limited scope presents different risks from an older apartment undergoing a complete strip-out.
Track agreed costs and payments separately
In your budget spreadsheet, use separate columns for estimated cost, agreed amount, payments made and outstanding balance.
Add a column for changes as well. This keeps additional work separate from the original items and gives you a clearer forecast of the final cost.
5. Request comparable quotes
To compare contractors, provide everyone with the same scope of work. If one quote includes wall preparation and another covers painting only, the totals cannot be compared directly.
Ask each quote to specify:
- the individual types of work;
- quantities or the method of measurement;
- what is included in labour and materials;
- who purchases and delivers the materials;
- whether transport, waste disposal and cleaning are included;
- which activities are excluded;
- the arrangements for additional work;
- the payment method and payment stages.
Discuss the organisation too. Who coordinates the different trades? Who tracks deliveries? Who is responsible when one activity delays the next?
Assess how clearly the proposal is written
A detailed quote allows you to ask specific questions. A single total without a defined scope leaves more room for differing expectations.
Ask for examples of similar projects and discuss how the contractor handles problems, changes and corrections. Communication before work begins often indicates how issues will be addressed during the renovation.
6. Build a schedule around the order of work
The schedule should show not only when an activity starts, but also what needs to be ready before it can begin.
A typical sequence for a more extensive renovation is:
- Clear the apartment and protect areas that will remain.
- Carry out removal work and dispose of waste.
- Inspect the condition revealed by the strip-out.
- Make the planned layout alterations.
- Carry out electrical and plumbing work.
- Prepare substrates and complete wet trades.
- Install wall finishes and flooring, and complete finishing work.
- Install fixtures, doors and furniture.
- Complete inspections, corrections and cleaning.
This is a guide. The exact sequence should be coordinated according to the systems being used, site conditions and manufacturers’ instructions.
Some activities can run in parallel. Others require the previous work to be completed, inspected or given sufficient drying or curing time.
Include manufacturing and delivery lead times
The contractors’ schedule is only part of the overall timeline. A custom kitchen, doors or a particular flooring product may need to be ordered well in advance.
For each important delivery, record:
- when the product needs to be selected;
- when dimensions must be confirmed;
- when the order should be placed;
- when delivery to the apartment is expected;
- when installation can take place.
Do not base your moving-in date solely on an optimistic estimate for the final installation. Allow time for inspections, corrections and cleaning.
7. Organise materials and work within the building
Materials need to arrive on time, but there must also be a suitable place to store them. Delivering too early can obstruct the work or expose products to damage.
Before ordering, check the exact model, colour, size, quantity and compatibility with the other design choices. For flooring and tiling, the allowance for cutting waste depends on the laying pattern and the room’s geometry.
Clarify building access, unloading arrangements, how heavy items will be carried upstairs and where materials will be stored temporarily.
Consider the neighbours
Coordinate the work with the building’s rules and applicable requirements for noise and working hours. Protect communal areas and arrange regular cleaning after materials and waste have been moved through them.
These tasks may seem secondary, but they can cause disputes and delays if nobody is responsible for them.
If you will live in the apartment during the renovation
Plan which rooms will remain usable and how they will be separated from the work area. Clarify when water or electricity will be interrupted and whether you will have access to a functioning bathroom.
Renovating an occupied home often involves more moving, protection and phased work. Include this in the timeline and budget when discussing quotes.
8. Establish a clear process for decisions and changes
Questions arise during renovation that cannot be fully anticipated. You need to know who makes each decision and how it will be communicated to everyone affected.
Appoint a main contact for communication. Keep drawings, quotes, orders and the current schedule together in one place.
For every significant change, record:
- what is changing;
- why it is necessary;
- how it affects the cost;
- how it affects the schedule;
- who approved it.
Do not rely solely on verbal agreements. A brief written confirmation with a photo or updated drawing can prevent work being carried out using outdated information.
Inspect work before it is concealed
Checks are most valuable while corrections can still be made without damaging finished surfaces.
Arrange for the relevant specialists to inspect and test services before they are covered. Check connection points against the furniture layout and confirm that substrates are ready for the next stage.
9. Use a checklist for the final handover
Completing the last task does not automatically mean every detail has been checked.
Inspect the apartment room by room and record any outstanding issues. Check:
- the opening and closing of doors, cabinets and drawers;
- the operation of switches, sockets and lighting;
- water supply and drainage;
- connections around bathroom fixtures;
- appliance operation and access for servicing;
- the condition of flooring, wall finishes and painted surfaces;
- joints, seals and finishing details.
Agree who will resolve each issue and by when.
Collect equipment documents, maintenance instructions, warranties and available technical information. Keep paint and material codes, together with suitable quantities of leftover materials for future local repairs.
The most common renovation planning mistakes
Starting without a clear scope
When decisions are made gradually during the work, the budget and schedule keep changing. Define the main tasks before agreeing the work with contractors.
Choosing furniture after services have been installed
Furniture dimensions and positions determine many technical requirements. The order of planning is particularly important in kitchens and bathrooms.
Buying without checking dimensions and compatibility
An attractive product may be unsuitable for the intended installation. Confirm the technical requirements before ordering.
Comparing only the total price
A lower quote may include less work. Compare the scope and conditions to understand the actual difference.
Not allowing time for deliveries and drying or curing
Adding more workers cannot speed up every stage. Build the schedule around necessary waiting periods and confirmed delivery dates.
Making changes without assessing their consequences
Moving one appliance may affect cabinets, service connections and products already ordered. Check how the decisions relate to one another before approving a change.
A checklist before renovation begins
Before work starts, make sure you have:
- a defined scope and agreed priorities;
- an assessment of the existing condition;
- a confirmed layout and main furniture positions;
- the necessary technical plans and specifications;
- a budget with a separate contingency;
- clear quotes and agreed responsibilities;
- a schedule for work and deliveries;
- arrangements for access, waste disposal and protection;
- a process for approving changes;
- planned intermediate inspections and a final handover.
If any of these points are missing, resolve them before the relevant work begins. Every decorative detail does not need to be selected in advance, but decisions that affect construction must be made in time.
Frequently asked questions
Where should we start when planning an apartment renovation?
Start with your household’s needs and an inspection of the apartment. Then define the scope, layout and budget. This gives contractors specific tasks on which to base their quotes.
Can we get an exact price before the strip-out?
A detailed quote can be prepared for known activities, but concealed conditions may require additional work. Agree beforehand how this work will be assessed and approved.
When should we order the kitchen?
Kitchen planning begins before new services are installed. The timing of final measurements and ordering should be agreed with the manufacturer, taking account of the room’s readiness and production lead times.
Can the renovation be carried out in stages?
Yes, where the technical dependencies allow it. Shared services, continuous flooring and connections between rooms need to be considered in advance to avoid damaging completed work.
How long does an apartment renovation take?
The duration depends on the scope, the apartment’s condition, drying and curing requirements, deliveries and contractor coordination. A reliable schedule can be prepared once these factors are established.
