Completed Home Office Installation at our Deep Retrofit Project

As part of this wider deep retrofit renovation, we recently completed the installation of a dedicated home office space designed to integrate seamlessly within the overall performance upgrade of the property.

With more people working from home than ever, spaces like this need to feel practical, calm and well integrated into the home itself.

Alongside improvements to the building fabric, ventilation and heating systems, attention was also given to how the home functions day to day creating practical, comfortable spaces suited to modern living.

The finished result combines functionality, clean detailing and high-quality workmanship within a future-ready home environment.

We had an old damp draughty Victorian property, and upgraded it to a home for the future.
This property has undergone a full retrofit, transforming it into a modern, energy-efficient home designed for long-term living.
Alongside improvements to the building fabric with wood fibre insulation internal & external with lime plasters and renders, we’ve installed:
A heat pump
MVHR ventilation
Solar panels to both front and rear roofs
Battery storage
Together, these systems help reduce energy use, improve comfort and make the home far more efficient to run. All while maintaining its original character.
A great example of how older homes can be upgraded to meet modern standards.

What is MVHR, and why does it matter in a retrofit?

When homes are upgraded with insulation and made more airtight, ventilation becomes essential.
We install MVHR systems (Mechanical Ventilation with Heat Recovery) to provide:
A constant supply of fresh, filtered air
Removal of moisture and pollutants
Reduced risk of condensation and mould
Retention of heat that would otherwise be lost
The key is doing it properly. From design through to installation & commissioning we have all bases covered. So the system runs quietly and efficiently in the background.

A healthier, more comfortable home by design.

When it comes to retrofit projects, insulation and airtightness go hand in hand.

There is no point upgrading insulation if warm air is still leaking out through gaps, cracks and poorly sealed junctions.

A well-designed retrofit should do both, improve insulation to slow heat loss, and improve airtightness to control unwanted draughts and energy waste.

Why does that matter?

Because good insulation and airtightness can help

* reduce heat loss
* improve comfort
* cut draughts
* lower energy bills
* support better long-term building performance

The key is getting the balance right.

Retrofit is not just about adding more insulation. It is about understanding how the whole building works together walls, floors, roof, junctions, ventilation and moisture movement.

At Total Precision Developments, we look at the full picture to make sure retrofit work performs properly, not just on paper, but in real life.

Extending properties & Creating space safely its what we do.

To open up this property and allow for the extension, to another of our deep retrofit projects we installed structural steel beams to support the new layout.
This is one of the most important ,and potentially dangerous stages of any build.
It must be carried out by experienced professionals with the right planning and support in place. Especially now with architects and clients wanting big open spaces for windows, doors etc as you can see below not much was left of the corner of the house to get the steels in, yet in they went and the house is now more structurally sound than ever.
Once complete, the transformation is clear larger spaces, better flow, and a completely different feel to the home.
Another step in delivering a high-quality renovation.

PIR insulation or wood fibre insulation, which is better?

The honest answer is, it depends on the building.

PIR is a great option where you need strong thermal performance with a slimmer build-up. Typical PIR products are around 0.021–0.022 W/mK, so they can help achieve target U-values without taking up too much space.

Wood fibre insulation is a strong choice where breathability, moisture management and summer comfort matter more. Typical wood fibre products are around 0.043 W/mK, so they usually need more thickness, but they can help with moisture buffering and overheating performance in the right build-up.

At Total Precision Developments, we look at the whole picture:

* the type of property
* how the wall or roof needs to perform
* breathability and moisture movement
* space available
* and the overall goals for the project

There’s no one-size-fits-all answer. The right insulation is the one that works best for your property and the way it’s built.

📐✨ Smart retrofit upgrade!

We kicked out the roof to cover new external wall insulation (EWI) all the way up to the wall plate 👊. Then we:
🪵 Packed the roof with insulation
🌱 Added rigid wood fibre boards (natural + breathable)
🎨 Finished with lime render for a timeless look
💧 Installed sleek Lindab guttering + a rainwater harvesting fitting — so every drop of rain can be put to good use!

This means:
✔️ No cold bridging
✔️ Walls + roof fully protected
✔️ A breathable, long-lasting envelope
✔️ Rainwater ready for reuse 🌍

Retrofit done the right way = efficiency + durability + beauty.
