Private house reconstruction
A house may no longer meet a family’s needs, building services requirements or modern expectations for use and maintenance. This does not always mean it must be demolished and rebuilt.
Reconstruction can provide an opportunity for:
- a new layout;
- additional floor area;
- an extension;
- additional storeys;
- roof alterations;
- new openings;
- structural strengthening;
- upgrades to building services;
- insulation and energy efficiency improvements.
The starting point is an assessment of the existing building’s actual condition, before demolition work is considered.

Why is the house being reconstructed?
Typical reasons:
- The family has become very close;
- Changes in the design of life;
- We need an office;
- Additional bedrooms are needed;
- There is a need to combine the premises;
- A second light / other space is required;
- We need a new entrance;
- You need a terrace;
- We need an annex;
- I want to add a floor;
- The old roof requires complete replacement;
- Engineering systems are outdated;
- The house is not warm;
- There are moistures;
- Existing structures require repair or reinforcement;
- The house was built in stages and became an unharmonized system;
- An old house has been bought and has to be adapted to new owners.
Not every task automatically justifies reconstruction.
Sometimes rational:
- Repair;
- Partial modernization;
- Local restructuring;
- New construction.
This is determined after an object analysis.
Repair or renovation
Renovation
Usually:
- Refining;
- Internal engineering;
- Light partitions;
- Upgrading of surfaces;
- Equipment.
Reconstruction
May affect:
- A constructive scheme;
- The carrying walls;
- Curves;
- The foundation;
- The roof;
- Area;
- Annex buildings;
- superstructures;
- New major gaps;
- Change of load.
If the line is not clear, the actual composition of the work is first determined.
The existing building already has history.
The following should be considered:
- as they built it,
- What was changed;
- What they did;
- which networks were replaced;
- Where there are cracks,
- Where the moisture was;
- What a roof;
- What is the basis;
- What closures;
- I don't know what real materials are used.
Historic design documents are useful, but do not replace a condition survey.
What they're testing before the project.
Depending on the brief:
- Geometry;
- The foundation;
- Walls;
- Columns;
- beams;
- Curves;
- stairways;
- The roof;
- Cracks;
- Deformity;
- moisture;
- Hydroinsulation;
- Engineering networks;
- Heat contour;
- Previous changes.
The inspection is not always equal to a complete technical survey.

Documents and actual status
Useful:
- Old project;
- Plans;
- Trade and transport;
- Drawings;
- Photo of construction;
- Information on previous repairs;
- Documents on the annex;
- Engineering circuits.
But there are differences between documents and reality.
The actual pattern must be confirmed before the critical changes are designed.
Design details and work planning
Not all walls are the same.
The modification of the layout may include:
- Transport of partitions;
- Integration of premises;
- New zoning;
- Change of ladder;
- A new sanitation facility;
- Kitchen transport;
- A new entrance;
- New gaps.
Before intervention, it is necessary to determine:
- Which are the load-bearing walls,
- Where the networks pass;
- How the closures work;
- Whether there's an engineering possibility to transfer functions.
The size of the gap is not a major question.
You need to know:
- The role of the wall;
- Loads from above;
- Type of closure;
- Material;
- Existing damage;
- The need for temporary support;
- a way to strengthen it.
The design solution is individual.
The new volume has to work with the old house.
The Annex requires agreement on:
- Landing;
- The foundation;
- Sediment;
- Deformative solutions;
- Construction connection;
- The roof;
- Water discharge;
- Warming;
- Facade;
- Engineering systems;
- Sex markings.
Special attention:
The old and the new one.
It's where it's common:
- Cracks;
- Leaks;
- Cold bridges;
- It's a problem to fix it.
First, can an existing house accept new burdens?
Before a decision is taken, it is necessary to evaluate:
- The foundation;
- The carrying walls;
- Columns;
- Curves;
- rigidity;
- The roof;
- Possible reinforcements.
Sometimes lightly designed superstructures can be more rationally heavy.
But the choice of the system is a project task.
Foundations
Reconstruction can change the load.
Therefore, in the case of significant changes, it is necessary to understand:
- Type of existing foundation;
- Actual geometry;
- Grounds;
- Status;
- Cracks;
- Sediment;
- Water;
- new loads.
It is only required when there is a proven need.
Closures
The objectives of the renovation are as follows:
- New openings;
- stairways;
- Strengthening;
- Replacement of sites;
- Change of load;
- New equipment.
Any intervention must take into account the actual design of the closure.
Blood
Renovation of the roof may be related to:
- Full updating;
- A change of shape;
- The mansard;
- A superstructure;
- Warming;
- New windows;
- A drain;
- Ventilation;
- Engineering passageways.
The new roof shall be agreed with:
- The walls;
- Loads;
- Warming;
- Facade;
- Water drainage.
Renovation is a good time to fix system heat problems.
The following may be considered:
- Warming;
- Windows;
- The cap;
- The roof;
- Interfaces;
- Cold bridges;
- Leakproofness;
- To protect the sun.
But energy efficiency is not just an additional layer of heater.
ZeroHouse
You can't close the cause with new trim.
Check possible sources:
- The roof;
- Facade;
- The foundation;
- Ground water;
- Water supply;
- Sanitation;
- condensate;
- Ventilation;
- Bridges are cold.
First, the reason is then the repairs.
Building services upgrades
Reconstruction is often the best moment to update:
- Electricians
- Heating
- boiler room;
- warm floors;
- Water;
- Sewage;
- Ventilation;
- Conditioning;
- Poor systems;
- Automatics;
- Back-up.
Existing networks are not considered to be automatic.
Boiling and technical premises
When changing houses, it's important to check:
- Existing equipment;
- Access;
- Power;
- Ventilation;
- Hydraulics;
- Service space;
- new loads.
Back-up food and self-sustainment
The renovation provides an opportunity to anticipate:
- Critical electrical groups;
- Inverter and battery systems;
- The connection of the generator;
- pumps;
- Heating management;
- Internet;
- Security;
- Gate;
- Lights.
ZeroHouse / AVGZ — according to the agreed scope.
The new layout must be implemented
Architecture / interior design should take account of:
- Existing design;
- New reinforcements;
- Engineering mines;
- The ceilings;
- Levels;
- Furniture;
- Doors;
- Equipment.
MultiStyle
Reconstruction is the worst case for a square value.
Value is influenced by:
- Reference status;
- volume of survey;
- Dismantling;
- Hidden defects;
- Temporary reinforcements;
- Design;
- Annex;
- Construction;
- The roof;
- Engineering;
- Warming;
- Facade;
- Refining;
- Logistics.
Design details and work planning
It's impossible to know before the autopsy.
Sometimes hidden:
- The actual composition of the wall;
- Arming;
- The beam condition;
- Tubes;
- Cables;
- Hydroinsulation;
- The foundation;
- Old openings;
- Previous reinforcements.
The contractor's task is not to promise that there is no unknown.
The challenge is to determine in advance:
- How new circumstances are recorded;
- Who makes the decision;
- How the project is adjusted;
- How the estimates change;
- I don't know how time changes.
Changes in the process
Any significant change shall be estimated by:
- by design;
- Engineering;
- Price;
- Time frame;
- The work already done.
Changes affecting the structure require a design review prior to the completion of the work.
Is it possible to live in a house during reconstruction?
Sometimes it's possible in a step-by-step scheme.
But we have to consider:
- Dismantling;
- dust;
- Noise;
- Disruption of water;
- Heating cut-off;
- Disablement of electricity;
- Open contour;
- Security;
- Construction passageways;
- Temporary entrances.
Copy production:
Whether residents can remain depends on the extent and phasing of the work. During substantial structural work, moving out temporarily is often safer and more practical.
Phased reconstruction
It may be useful if:
- The house is used;
- The budget is allocated;
- Several independent zones;
- The annex is built separately;
- Engineering is changing lines.
But the sequence has to be design.
You can't fix a piece of the house if the next stage of the design requires it to be destroyed again.
How do we start?
02. Existing project documents
Plans, photos, documents.
03. Measured survey
Actual geometry.
04. Site visit / condition assessment
State of the house.
05. Concept
What we save, change and add.
06. Design
Architecture, structural design and building services.
07. scope of work and cost estimate
Which comes in handy.
08. Phasing
Dismantling and construction procedures.
09. Delivery
With the control of the critical stages.
10. Building services
Network upgrades.
11. Finishes
After the design and engineering stages.
12. Handover
Let's fix the result.
What can be passed on to PNVTeam
Possible composition of work:
- Analysis of the original task;
- Organization of measurements;
- Coordination of the survey;
- Design;
- Dismantling;
- Temporary reinforcements;
- constructive work;
- new openings;
- Annex;
- Construction;
- The roof;
- Warming;
- Facade;
- Engineering modernization;
- Inner trim;
- Co-ordination of related actors.
It's a possible composition of work, not an automatic package.
Formats of cooperation
There's a remodeling project ready for you.
We're checking the documentation and the composition of the work.
There's just an idea.
Let's start with a survey and a concept.
The house is already in part.
Let's start by recording the actual status.
Only a separate phase is needed

Reconstruction of a private house
Only part of our completed work is publicly available.
Questions and answers
With plans, photographs, descriptions of the desired changes and an assessment of the actual state of the house.
Feasibility depends on the site, existing structure, foundations, additional loads and design solution.
Only after an assessment of the capacity of the existing house to absorb the extra burden.
Sometimes it is possible, but the solution requires an analysis of the constructive design and the strengthening project.
If the task involves design, a sufficient survey is usually needed before the design solution.
Yeah, as background information, but it's not a substitute for actual measurements and real-state testing.
Sometimes, yes, the phase must be agreed so that subsequent work does not destroy what has already been done.
Depends on the volume of interventions and engineering outages.
The cost is determined by the baseline, the project and the actual volume of the work, and the price of the area is not reliable.
Record the actual status, determine the technical solution and agree on the modification of the project/estimate to the dependent works.
Only if included in the agreed composition of the work.
The conditions of guarantee are determined by the contract and the type of work.
What to Send for First Assessment
Useful:
- Plans;
- Old project;
- Photos of facades;
- Photographs of the interior;
- Photo of cracks / moisture;
- Illustrative area;
- :: deck capacity;
- Year of construction, if known;
- Information on the annexes;
- Description of the changes desired;
- Existing engineering;
- Survey results.
Don't demand a complete set.
You want to change the existing house, not build a new one from scratch?
Send plans, photos and a brief description of what you want to change.
If there's an old project, add it.
After initial analysis, it can be determined that:
- That you need to be examined;
- What changes are technically feasible;
- What kind of project is needed;
- I don't know what the next stage makes sense.
Briefly describe your project and leave your contact details. If we need further information to provide a useful response, we will explain what to prepare.
