Design & Build is appealing to homeowners for numerous reasons:

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.

No, we are restricted in where we can operate because we need to travel to site each day to carry out the work. Here is a link to the areas we cover

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.

Uniquely, a deep retrofit by RENOVA includes interior design plus a complete refurbishment and redecoration of your home. This means that not only will your home feel more comfortable, but it will look better than ever too. It may even be reconfigured and extended.

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

A deep retrofit is the renovation of the fabric of a building plus its mechanical and electrical services. This 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.

Yes, while we specialise in deep retrofit renovations we are perfectly happy to carry out a cosmetic renovation if that is all that is required, which would typically be in the case of a modern house. Click here to see an example of a a cosmetic renovation we carried out.

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. This is because once a new cosmetic veneer is installed it is impossible to see to the retrofit works afterwards without undoing the cosmetic works.

Yes we do.

While we specialise in making existing houses better, we occasionally make them bigger too. Approximately 25% of our renovations include an extension, which we always design ourselves. If planning permission is required for your extension we will apply for that for you.

Yes. Our designers will propose a suite of finishes and fittings for your new home. Are finishes and fittings can be selected at our studio in Kilcoole where we have samples of everything from timber floors, to kitchens, to bathroom fittings and everything else you will need to renovate your home. Our experienced designers and studio make it simple to select finishes and fittings.

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

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 €1,700 per m2 for a Deep Retrofit renovation including finishes, design and management as detailed below.

In our experience mid-specification Retrofit works costs from €900 per m2 for the following:

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

The cost of fit-out and finishes are additional and, in our experience, the budget for this part of the works needs to be from €800 per m2. Fit out & finishes normally consists of the following:

  • 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

The rates of €1,700 per m2 also includes the following:

  • Concept design + budgeting
  • Interior design
  • Working drawings
  • Project planning
  • Structural engineer
  • Project management
  • Contractors insurance cover
  • Health & safety
  • Site operating overheads

Total cost above for a RENOVA Deep retrofit renovation is from €1,700 per m2

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

  • Furniture removal and storage
  • Insulating a suspended ground floor / installing an insulated concrete floor
  • Heat pump instead of boiler
  • Underfloor heating
  • Solar panels
  • AluClad windows instead of PVC
  • High end kitchen, e.g. Noel Dempsey Design
  • Built in joinery, e.g. alcove units
  • Repair works – e.g. re-pointing, re-roofing, damp treatment
  • Asbestos removal
  • Stove
  • Curtains
  • Carpets
  • Kitchen appliances
  • Loose Furniture
  • Paving, gardens, boundaries
  • House extension
  • Planning applications
  • BER consultant & SEAI application

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.

At RENOVA, we will always endeavour to tailor a scope of works to suit your budget. So, if you budget doesn’t quite stretch to €1,700 per m2, speak to us and we’ll advise on how best to spend the budget that you do have.

The figures above are based on a typical 3 bed semi-detached house with 2 bathrooms 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 recommend budgeting at least €850/m2 for a cosmetic renovation

This is more difficult to say. However a good place to start is the RIAI Construction Cost Guidelines that are available here

On page 8 they advise a budget of €1,900 – €2,300 per m2 excluding VAT, design fees, external works and fitting out. For an extension we always recommend getting a quantity surveyor to prepare a job specific cost plan to establish the likely cost. This is because extensions can vary so much from one to another.

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. This will be broken down into cost centres so that you can see how the costs might add up. Our quantity surveyor has 25 years experience and RENOVA have carried out over 100 renovations since 2012 so you can be confident in our pricing. We believe it is important to address the potential cost of your renovation before progressing with design work.

Because of our experience we are able to notify you of the potential cost of your renovation after our first visit. And it is not unusual for our budget estimate to be higher than expected.

If the potential cost is higher than expected we advise on the best possible alternative scope of works that would be affordable. It is essential that the brief and budget are aligned before proceeding to design.
