No, we don’t.

At RENOVA we specialise in maximising the potential of existing houses, we do not extend. Our business model no longer supports the construction of extensions, it focuses on the potential of the existing footprint of the house.

Efficient and imaginative reconfiguration in conjunction with deep retrofit transform the houses we work on into adaptable homes designed for sustainable modern living.

If you require a house extension then we recommend that you to engage with an RIAI registered architect instead.

Our jobs typically do not require a planning application. However, if your renovation needs planning permission, then we can look after that for you.

Based on current resources we currently cover:

  • South County Dublin,
  • East County Wicklow
  • North County Wexford.

On occasions we have carried out a deep retrofit to part of a large house, for example to the ground floor only. However, we do not a diluted version of a deep retrofit. We always do the full suite of works to the space we are working on.

We do not do ‘small jobs’ like bathroom renovations, kitchens or the removal of a wall for example. Theer are plenty of companies that specialise in these types of jobs and are set up to do this size job.

No, we just provide design services on projects that we are building ourselves. For a design only srvice we recommend engaging with an RIAI registered architect.

A deep retrofit is a complete overhaul of the fabric of your home and it’s utilities, with the aim of improving energy conservation and comfort levels in a home.

A deep retrofit includes: roof, wall and floor insulation; new windows and doors; airtightness, ventilation, and improved heating, plumbing and electrical systems.

A deep retrofit by RENOVA also includes all new fittings and finishes and redecoration of your home. This means that not only will your home feel more comfortable, but it will look better than ever too.

A cosmetic renovation involves the refurbishment of the aesthetic elements of your home, i.e. its finishes and fittings. A cosmetic renovation improves how your home looks. It does not address its insulation or heating. electrical, plumbing and ventilation systems.

After a cosmetic renovation your home will look great but it won’t be any more comfortable or energy efficient.

A cosmetic renovation typically includes kitchen, bathrooms, storage, fireplace, flooring, doors, skirtings, light fittings, painting and decoration.

Until recently a ‘house renovation’ meant renovation of the fittings and finishes in a house to improve and modernise the aesthetic of a house. This would include the following and is described as a ‘cosmetic renovation’:

  • Kitchen
  • Bathrooms
  • Flooring
  • Wardrobes
  • Fireplace
  • Internal doors, skirtings, architraves
  • Flooring
  • Painting and decorating

‘Deep retrofit’ is a new concept and focuses on the renovation of the fabric of a building plus its mechanical and electrical services. These are:

  • Heating system
  • Plumbing
  • Wiring
  • Windows and external doors
  • Wall insulation
  • Roof insulation
  • Ground floor insulation
  • Acoustic insulation
  • Air tightness
  • Ventilation

A deep retrofit requires a far more comprehensive strip out of the existing house, right back to bare walls and timbers.

If you take on a deep retrofit renovation you are committed all of the cosmetic renovation works in addition. It is not possible to carry out the deep retrofit works above without needing to do the bulk of the cosmetic works too.

In our experience a deep retrofit renovation is twice the effort, twice the duration and twice the cost of just doing a cosmetic renovation.

If you undertake a deep retrofit renovation your home will become the equivalent of a new house. It will be comfortable and energy efficient, and naturally your running costs will be reduced too.

While undertaking a deep retrofit you will have the opportunity to reconfigure your home to perfectly suit your needs too.

An often overlooked benefit is that you will know that your house is perfect and can rest assured that you will not need to carry out any upgrades or maintenance for many many years to come. Your will know that your home is perfect right back to its blocks and foundations.

A cosmetic renovation is appropriate if the insulation and utilities at your home are modern and functioning properly. In this case it is reasonable to carry out a cosmetic renovation and just install new fittings and finishes.

While RENOVA specialises in deep retrofit renovations we are perfectly happy to carry out a cosmetic renovation if that is all that is required.

However, if a client asks for a cosmetic renovation but we feel that the house needs more we will always advise that the ‘under the bonnet’ retrofit works are addressed before a cosmetic renovation is undertaken.

We would never undertake a cosmetic renovation if a deep retrofit is needed. We could never cover over poor insulation and heating for example with new finishes.

As with all construction works, the cost of a Deep Retrofit renovation depends on the scale of the project and the specification of materials and finishes.

As a very rough guideline, we advise customers to budget from €1,800 per m2 for a deep retrofit renovation including fittings & finishes plus design & management as detailed below.

Standard retrofit works are as follows:

  • Strip out works
  • Wall insulation (drylining)
  • Attic Insulation
  • Airtightness
  • Windows and doors
  • Electrical re-wire
  • Light & power
  • Heating system and heating controls
  • Plumbing
  • Ventilation

Standard fit-out and finishes are as follows:

  • New ceilings
  • Internal doors
  • Skirting boards and architraves
  • Kitchen allowance
  • Bathroom fit-out
  • Wardrobes
  • Fireplace
  • Timber flooring
  • Tiled floors
  • Painting & decorating
  • Attic flooring and storage

Also included in the rate of from €1,800 are the following:

  • Quantity surveyor – budgeting.
  • Architectural design
  • Interior design
  • Construction drawings
  • Structural engineer
  • Project management
  • Contractors insurance cover
  • Health & safety costs
  • Site operating overheads
  • Value added tax 13.5% (VAT)

The following are excluded from the works listed above and will incur additional costs:

  • Layout changes – cost varies depending on design
  • Insulating a suspended ground floor – not always an option
  • Repair works – e.g. re-pointing, re-roofing, damp treatment, asbestos removal
  • Relocating utilities such as ESB meter if required
  • Heat pump instead of boiler
  • Underfloor heating instead of radiators
  • Stove
  • Solar panels
  • AluClad windows instead of PVC
  • Hand painetd kitchen – e.g. by Noel Dempsey Design
  • Built in joinery, e.g. alcove units
  • Curtains
  • Carpets
  • Kitchen appliances
  • Loose Furniture
  • Planning application if required
  • BER assessor
  • External works – patio, driveway, gardens etc

Always bear in mind that tastes and expectations vary greatly when it comes to fit-out and finishes, so naturally the cost of fit-out and finishes can vary greatly.

The figures above are based on a typical 3 bed semi-detached house with 1 bathroom and a WC, circa 100m2. Economies of scale have an impact on the rate per m2. A smaller house will cost more per m2 and a larger house can cost less per m2 for the same works.

NOTE 1: Our pricing always includes design and management plus all fittings and finishes and VAT for a full turn-key service.

NOTE 2: The information above is provided as a guideline only. Do not make any financial decisions based on the information provided here.

In our experience approximately half the cost of a deep retrofit renovation.

We do not set a minimum budget.

However, due to the comprehensive nature of our deep retrofits, it is rare that a job costs less than €175,000.

Our quantity surveyor will be the first person you meet.

After their first visit to the house they will be able to provide you with a reliable budget estimate for your project.

Because of our experience we are able to notify you of the potential cost of your renovation after our first visit. This is a budget estimate.

If the budget estimate is higher than expected, we can advise on the wisest ways to reduce costs.

It is essential that the brief and budget are aligned before proceeding to the design stages of any project.

At RENOVA we are the only company in Ireland that specialise in domestic deep retrofit renovations.

We are also a genuine design & build company. This means that we take care of everything for our clients and they need only deal with us from initial enquiry through to handover.

We guarantee a completely stress-free experience every time. Our service is swift and prompt, and when we say that your projects will cost €X, you can be confident that this is correct.

RENOVA will also bring strong management skills and quality of service to your project and then combine the best people and products to complete the job to the highest standards. If you scratch the surface of other retrofit companies, you’ll often find that they are really insulation or plumbing companies that have decided to expand the scope of their services.

Above all else RENOVA personnel are all experienced. Our management team have renovated hundreds of houses and have an average of 20 years experience each.

Our studio is a great location to learn about the technical elements of the project and to select all of your finishes too.

No one else we know of provides the professional input at design stage to ensure you get the right end result.

Design & build is when a single entity is responsible for the design and construction of a construction project.

A true partnership:

Design and build promotes the partnering of the builder and the homeowner from concept stage right through to handover. This allows us to fully understand you and your expectations for your renovation project.

Single-source accountability:

With design and build, we alone are responsible for the quality of design and construction, for sticking to the budget and for meeting project deadlines. So, whatever your questions or concerns, you can come straight to us.


You deal with one firm only throughout your project. As a result, you do not need to co-ordinate the efforts of a designer, a builder and assorted sub-contractors.

Time saving:

Our design and construction specialists work closely together to complete their tasks concurrently, which compresses the time frame for project completion.

Client satisfaction:

All of the above factors contribute to a more successful and satisfying renovation project – for you and for us.

Yes we do.

We have a complete design office and several construction crews.

We can manage every aspect of your renovation from the first meeting right through to handover. Naturally we do all of the design and retrofit and fitout works, but we can also do the finishing touches such as blinds, carpets, gardens if required.


When you engage RENOVA we take care of everything from initial budgeting right through to final handover.


You will need to move out for the full duration of the works. You will also need to remove your house contents.

Your house will become a building site, so for reasons of health & safety it is not possible to remain living in the house during the works.


If you have engaged the services of an architect, then your architect will tender to suitable building contractors through the traditional procurement process.

Yes you can.

If you have a design that you are happy with then so are we.

In this case we will can proceed straight to quotation. Our service will still include the preparation of working drawings, technical specifications and selection of fittings and finishes.

RENOVA does.

We have a fully staffed design office providing the following services:

  • Quantity surveying
  • Architectural design

This is made easy because we have samples of everything you will need at our design studio.

No, we are not agents for any product or material. We have several suppliers for every product that we require for a renovation. We will recommend these suppliers for your materials because we are familiar with their products and service. We are not obliged to any particular supplier.

We will specify the insulation and airtightness works.
