The larch rainscreen cladding is looking fantastic and really emphasis the window liners. The larch is untreated and will naturally silver grey over the next year or so.

The dark grey zinc with variable panel width now clads the link and the battens (all to be painted black) are being installed on the rotunda to receive the timber cladding. The one piece metal liners are also visible to the rotunda windows.

The Warmcel insulation was pumped into the walls this week. It’s always great to see a mountain of insulation on site especially as it’s recycled newspaper and will sequester carbon for decades to come. Devana insulation were great and even took a core sample to check the insulation density to avoid any risk of slump.

Works have started back on site and the airtightness layer is now complete. Above ground the taped OSB forms the airtightness layer including airtight boxes to house the lighting in the ceiling and battens to the wall to provide a service void and safeguard the airtightness layer. It was impossible to extend the airtightness on the ground floor with the airtightness on the first floor (i.e. through the intermediate floor) due to complicated structure and steelwork so instead, each room (on the ground and the first floors) are separate airtight ‘boxes’ but it does make detailing complicated! Below ground (in the basement) the foil face of the wall insulation acts as the air and vapour control layer and is taped to the Foamglas to the ceiling. The wall insulation is mechanically restrained by simple timber offcuts to prevent the insulation moving and straining the airtightness tapes.

The tour of the lodge on Saturday was very well received with lots of interest in the Internorm HV350 windows with integral blinds for solar control which are a fantastic piece of kit. If you missed it and want to be on the tour once works are complete later in the year, then get in touch

The tour this Saturday (14th) has been extended to include the Listed Lodge itself, which has exemplar secondary glazing and MVHR. Checkout the blog so far. Booking essential through jim@jimmillerdesign.co.uk

In the basement the timber studwork is being installed which supports the wall coverings and services but also provides an additional mechanical restraint to the insulation (which has been fitted without mechanical fixings to reduce cold bridging and condensation risk). Above ground the twin wall timber studwork is now complete with an external layer of woodfibre board which is fully breathable (making the wall build up robust and low risk) and will restrain the pumped insulation in due course.

We’re now about half way through the deep retrofit to the Listed Lodge to Passivhaus principles and it’s a great opportunity to look at the construction before everything gets covered up. Above ground there’s a twin stud wall with a cellulose based breathable build up, Internorm triple plus 1 fenestration with integral solar control and discussion on airtightness & overheating strategy. In the basement there’s an interesting solution to wall insulation, Foamglas to the soffit and MVHR ventilation throughout. Checkout the blog so far. The tour will take place Saturday 14th March at 11am. Booking essential through jim@jimmillerdesign.co.uk

Above ground the rotunda walls are being formed with a twin wall timber studwork creating a 350mm wide cavity ready for insulating, and plywood lines for the windows
Below ground in the basement the insulation is being bonded to the waterproofing membrane rather than being screwed to remove the fixings altogether and so eliminate the cold bridging (& simplify the works). Any risk of the insulation moving or will be negated once the free standing timber studwork is installed. Obviously a shame to use oil based insulation, but below ground it is perhaps more robust as the waterprofing membrane is fairly air and vapour tight, definitely cheaper, provides an integral vapour control layer and thermal mass is not a benefit in this situation.

Works have commenced above ground by stripping out the two storey rotunda, which was only built in 2012 but was so poorly designed and detailed it couldn’t reach a comfortable temperature in winter, massively overheated for the rest of the year (sometimes both on the same day!), and was totally unusable as bedroom due to the 360 degree glazing and no openable windows. The airtightness was an almost criminal 17 ACH but being an extension means this doesn’t contravene the Building Regulations. The world can’t keep building rubbish like this if we want to have any hope of mitigating the climate crisis.

I’m planning a tour of the deep retrofit of a Listed Building in Hove sometime in the New Year when there should be lots to see before all the works are covered up. Period secondary glazing and MVHR to the Lodge, retrofit waterproofing and insulation to the basement, rebuild of the link and rotunda with MVHR throughout and all to Passivhaus principles. Can you let me if you’d be interested and if a weekday lunchtime tour would make sense.

The listed Lodge was remodelled in 2012 along with a massive extension including glazed link, rotunda, basement, garage and indoor and outdoor pools. Although works were only completed around 2012 there were so many issues with the oringinal design and implementation that Jim Miller Design were appointed to rethink the entire project from scratch. The lodge itself has already benefitted from secondary glazing and a whole house ventilation system (MVHR) but It’s taken 4 years of painstaking investigation and planning to get to a position to be able to commence with rebuilding the extension.
The basement alone is 100m2 and was built without adequate waterproofing or insulation to the walls! The photos show the cavity drain membrane system applied to the walls and the Foamglas insulation to the soffit (ceiling). Foamglas is installed with bitumen creating a completely impervious layer, which is critical in this unusual situation and will last for decades so meeting the ‘Do it once and do it right’ mantra.

My favourite builders go that extra mile to gain access!
