Demolish and Rebuild!

Demolish and Rebuild!


Penarth, South WalesMadness by the sea

In the Victorian sea side village of Penarth,(South Wales) also known as Garden by the Sea ,there are rumours spreading questioning the sanity of its residents.
Is it age or maybe the sea air that is effecting their logic? For in Penarth over the last year alone residents of the sleepy seaside village have witnessed no less than four seemingly good houses demolished and rebuilt on the same footprint as the old property.

Are these people crazy? What is the logic in taking down a perfectly good structure?

Victorian Terrace in PenarthEconomics is driving them sane

The truth is that these people have researched well.
Consider, they have just bought a property in an area they love or have lived in it for a long time and don't want to leave the area. Due to the age of the property, it is in need of an upgrade. It will require new windows, doors, re-wire, re-plumb, a new bathroom and kitchen.

When all of this work is being carried out the plaster will be hacked off to renew the services and the floor boards lifted. Undoubtedly their will be unforeseeable damage which the builder will claim EXTRA's for!

Pembroke TerraceThen there is that little bit of re modelling required to modernise the living area. Maybe two rooms into one ? or a small extension and orangery? The roof may be OK for now however it will need attention in a few years and they have been informed by the surveyor that there are signs of wood worm and no felt under the slates.
The amount of work needed dictates that they will have to vacate the property for a few months and further more they have to get the improvements passed through planning control.

They then calculated that after all this work that they will do (probably funded by a top up mortgage or loan) they then have to consider their fuel bills when they finally occupy the old house.

So What is left of the old property before all of these improvements are made? An old shell, a shell that is inefficient energy wise. The new improved property will look superb but will cost a fortune to heat.

20% paid by taxes

Pembroke TerraceThe people in question above have looked more closely into the finances. They realise that to demolish the old house will only take a week. It will only take a couple of weeks to re build completely in STYROSTONE. BUT THE MOST IMPORTANT FACT is that by building it from new they are eligible to reclaim all the VAT @ 20%. They also now have a brand new super insulated energy efficient house that will cost pennies to run. The VAT reclaim along with the disposable income provided by energy savings will more than pay for the cost of the styrostone shell.

Not so crazy

They are now the owners of the most valuable house in their areas.

Older properties were built with much larger gardens than today's properties in order that the occupants could grow their own produce.

Why not stop looking for that small plot tucked away between other properties and look at the viability of buying an older larger house with a big garden and go CRAZY!

Pembroke terrace case study

Retrofit and renovation of a Victorian Terrace in Penarth.

Retrofit and renovation of a Victorian Terrace in PenarthThis was an end of terrace which we renovated to improve the energy efficiency and reduce carbon emissions.
We then built a new property on to the end of this in StyroStone which boasts walls , and roof of 0.14 u value. It is made air tight using Siga membrane throughout the roof and a range of Siga tapes and products around windows etc. The whole project supersedes all building reg requirements.

I think it is a fantastic example of Victorian and modern build in harmony alongside each other

This project involved the complete renovation of a Victorian end of Terrace to modern standards.
All that remained of the existing building was the frontal facade and half of the roof! Every wall and floor was removed and replaced with new super insulated walls ans floors and a heavily insulated roof .

Ducts are pre installed for MVHR and the property now has underfloor heating to ground floor and rads to upper floors. The hot water is supplied via an A rated gas condensing boiler. Planning has been granted to build a new unit onto the end of this property. This will commence shortly and the new dwelling will be built to levels in accordance with passive house standards.

The main fabric of the building is to be StyroStone 350mm blocks which will provide a U value of 0.147.
We anticipate fitting solar thermal panels to both properties and introducing thermal stores, rainwater attenuation measures as well as MVHR to ensure that the properties are future proofed.
