We have been busy as ever, but managed to fit in this lovely letter porch extension with external cladding to either side, this modernised the whole look of this 1960s detached house.
We were commissioned to build the porch bay extension, but ended up changing the construction method to timber frame from block and brick for a few reasons which included.
Quicker to erect
More installation could be installed
Services would be easier to install
Better grounding for the triple glazed windows
We started by pouring the foundations but these had to be poured into a DMP because of nearby tree roots.
NOTE: If you are thinking of building and extension please be aware that any leylandii trees may need to be removed if they are within ten meters of you new build.
Then as we can see from the image below we build a cavity wall with 100mm thermalites up to damp course.

We then attached the damp course to the underside of the 180mm cls and fixed with sleeved fixings to create our sole plate.
Sole plate for timber frame
As we can see from the image above all the construction took place without the need to expose the inside of the building unnecessarily, we also used 180mm timber so we could reach the U values with 180mm celotex.
We then constructed the timber frame with is clad with sterling board and breathable membrane this is for the windows to sit on as we can see by the image below.
Foundation brickwork and timber frame
We then had to wait for the windows to be built and fitted, then we could continue with the build by erecting the roof which sits on a plate at the top and a 75 mm cls on the window frame.
Hand cut double hipped roof
We then have the basic construction of the roof which was then membraned and tiled we also clad the timber frame and the sides of the extension with hardiplank could sail cloth for the modern look, we also added a cant brick plinth with lead flashing which was not on the drawing as this looks better.
Completed bay with cladding
The existing windows inside were removed and the dwarf wall cut away to make the new bay inside the main front room.
We can now see the finished article apart from some tidying up and below is the inside where we were asked to install a brushed oak hardwood floor.
Finished inside with oak floor
This project came in on time and with budget although, as always we were asked to do lots of extra work which was not on the drawing which we are always happy to do.
Haven’t posted for a while as been extremely busy with a large flat roof dormer on a Victorian detached property in Foxhall Road Ipswich for an extremely pleasant client and there family below we can see the front of property.
We were commissioned to convert the current three bedroom home, into a four bed-roomed three storey loft conversion with stunning views over Ipswich.
As we can see from the picture the whole roof has been stripped of slate for the rear dormer and from the front to be membraned as there was no felt.
Rear of roof being stripped
The loft conversion will incompass a large bedroom with good sized en-suite and a custom built walk in wardrobe over 30 square meters of conversion with side and fold rear doors to a stylish glass Juliet balcony we have also installed three velux and reproofed the entire front of the property with the existing welsh slate.
Velux on slate roof
We have currently installed the new floor stairs, steel flat roof and clad the cheeks of the dormers with finer cent slate which can be vertically hung.
Below we can see the main room of the conversion from the bifold door postion
We have also insulated the flat cold roof with 160mm celotex and the exterior walls with 100mm and the internal walls with 70mm.
Complete loft conversion have started another conversion on a one hundred year old property for our new clients the loft will have three velux roof windows in the front and a huge dormer window at the back.
I haven’t posted for a while because we have had issues with the website and Talk Talk who were handling our business broad band (badly) I would not recommend them in a million years.
Anyway we are still converting lofts in and around the Ipswich Suffolk area along with other projects including Foxhall rd which we have installed new floor, stairs and steels ready for the massive 6 meters dormer clad with slate on the back of the property.
The floors concept of 8×2 C24 timbers sitting on the external walls and the internal load bearing walls to accept the 22mm caber floor.
As we can see from the images the loft is a hand cut roof with no felt so the whole of the roof is being membraned while the scaffold is up.

As the property is over 100 years old and the chimney stack is still in use we needed to provide a 90mm x 90mm post to hold the ridge beam up.
Nationaltradesmen.co.uk is a new website and app based service for the construction industry which provides a platform for construction operatives to find work and for companies to find tradesmen with specific skills and safety qualifications.
Nationaltradesmen has been built by tradesmen for tradesmen and the construction industry it has been engineered for construction workers and employers for building sites and larger construction projects which means the system works as a middle man between employers and employees.
Gregory Nelson founder of Nationaltradesmen.co.uk said: “As a tradesman I always struggled to find construction work in my local area so thought I would try to solve the problem by creating a website and app where tradesmen and companies can meet”
“Being a tradesmen I understood that if you were a tradesmen, you not only need to specify your trade, but the skills associated with that trade because not every carpenter does shuttering, and not every plumber is gas registered, that’s why we have put together a complete skills section for every construction job including what qualifications they hold and what CSCS card they have”.
“Workers can use Nationaltardesmen.co.uk to build a profile of skills and qualifications that be updated as the operative progresses through their career, employers who are registered can search for tradesmen who are registered with us for free and contact them for free”.
“We also offer to registered users free job postings for the first three jobs and thereafter it is only £5 a job”.
Nationaltradesmen.co.uk has also built apps to accompany the website these are available on Apples app store, Google play, Amazon Apps and the Windows store. Through our apps workers can search and apply for jobs in their area and employers can match workers with specialist skills and trades in specific areas.
Nationaltradesmen.co.uk also has also incorporated forums and blogs for those who are registered to post about tools, work or construction courses.
The site also has trade specific areas within the forum for all the different trades with instant messaging, member’s areas and a supplier’s directory for anyone involved in construction to upload their logo and link to their own website.
The website, mobile site and apps are being launched on 02/04/2016 to register you interest please visit our coming soon page here at Nationaltradesmen.co.uk.
Havent posted for a while but thought I would post up a couple of pictures of recent loft conversions the pictures below are of the I joists being installed I joists are a structural beam which negate the need for steels and can be installed by removing the first four rows of tiles and then being slid in to sit on the existing plate, also not the JES (joist end support) to give the joist riggidity when cut to fit in the eaves.
We can also see the gluelams before installation, gluelams are a structurally graded beam which come in standard and custom sizes the beauty of gluelams is they do the same job as a steel but are lighter stronger and easier to install and fix to and can also be cut on site to requirements.
glulams before install
With beams of this size and nature there is an issue with getting them up to the second floor so we usually hire in a crane and a banks man to help our team with the lifting as we can see below.
As we can see the creation of a new floor above the existing building has begun once the beams are in place the next of the work can continue the creation of the stair well with gluelams and hangers connecting the old and existing joists to support them around the stair well and the creation of the ashler walls and the ceiling ties to support the new structure before the old fink trusses can be removed as shown below.
After trusses removed
So the existing structure is removed the weight is transferred onto the ashler walls which are the small walls in the corner which then transfers the weight onto the new I joists and the gluelams onto the wall plate of the existing building so what next we need light.
Dormer under construction
As we can see we now need to create natural light by adding dormers by supporting the trusses either side with extra timbers for strength and remove the existing tiles battens and felt carefully before building the pitched roof dormer in this case there will be three so more to come when they are buit ok.

Converting your loft is the best way to maximise the value of a house, adding a further bedroom or bathroom with a loft conversion remains one of the best ways to bring in an extra return when adding value and space to your property.
One of the biggest decisions loft conversion companies face when carrying out a conversion is which insulation to use,as this can not only affect compliance with the Building Regulations, but can also have a big impact on the living space within the room so it pays when doing a loft conversion to do your research.
Underthe new U values and the latest version the U-value for pitched roofs insulated at rafter level remains at 0.18 W/m².K, whilst for flat ceilings the minimum is 0.16 W/m².K.
A well-insulated loft conversion can also reduce heating bills and CO2 emissions. This means home owners should not only see the financial benefit o, but also indirectly with an improved Energy Performance Certificate (EPC). Recent research suggests that this can significantly raise the value of a house when home owners are looking to resell.
Insulating to the Building Regulations with traditional products such as mineral fibre can be a pain, with the thicknesses required to achieve the desired performance often exceeding the rafter depth and seriously cutting into the headroom space that’s why many opt for Celotex or a rigid insulation board .
Which is less likely to sag or slump, resulting in un-insulated pockets, which can in turn lead to thermal bridging, surface condensation and mould growth.
Rigid boards has a fibre-free core, is unaffected by air-infiltration and is resistant to ingress from moisture or water vapour and many other environmental conditions. This allows it to maintain its thermal performance throughout the life of the building when correctly installed.
Many loft conversion companies are also using space blankets which have come down in costs considerably and can be used in conjunction with rigid insulation to achieve very high U values when installed properly, some loft conversions are using rigid board inside the rafter space blanket and the plasterboard with further insulation behind.
Loft conversion u regs
Kingspan Kooltherm have released the following guidelines to help loft conversion companies and builders reach these new guidelines which are as follows.
For houses with shared roofs and when the roof covering is not being replaced, the best approach is to install insulation between the rafters with a further layer of insulated plasterboard below. This ‘between and under’ approach helps to reduce thermal bridging through the rafters.
The Building Regulation requirements can be met by installing 100mm Kingspan Kooltherm K7 Pitched Roof Board between rafters and 39.5mm Kooltherm K14 Insulated Plasterboard below. As the space between rafters may vary it is essential to measure each gap before cutting to ensure a tight fit. Any gaps are filled with an expanding insulated foam and / or flexible sealant.
Where a non-breathable sarking material such as felt is used, a ventilation gap of 50mm is required above the Kooltherm K7. To maintain this gap and ensure the board is flush with the bottom of the rafters, timber stop battens can be nailed to the rafters at the appropriate depth.
The plasterboard is then fitted with the long edge running horizontally across the rafters, lapping by at least 20mm at joints. The boards are fixed in place with drywall screws at a maximum of 200mm centres, and no less than 10mm from the edge of the board at bound edges (paper bound) or 13mm from non-bound edge. Screws should be long enough to penetrate at least 25mm into the joist without being overdriven.
To meet the U-value requirement of 0.16 for areas of flat ceiling, 75mm Kooltherm K7 is fitted between joists and 69.5mm Kingspan Kooltherm K14 is added below using the same installation approach.
For dwarf walls 50mm Kooltherm K12 Framing Board is installed between timber studs and 29.5mm of Kooltherm K14 on their inner face.
When re-roofing a detatched property it is best to insulate using a “between and over” approach. For pitched roofs 50mm Kooltherm K7 Pitched Roof Board is installed between the rafters using sarking clips driven into the top of the timber at 1 meter centres to hold them in place.
A further 60mm of Kooltherm K7 is then installed over the rafters with care taken to ensure that any joints on boards running from the eaves to ridge occur over rafters. A breathable sarking membrane such as the company’s Nilvent is then overlaid and the boards can then be held in place with counter battens (38mm x 38 mm).
For enhanced airtightness with this arrangement a further breather membrane can be added between the two layers of Kingspan Koolthem K7, with all joints or gaps sealed using airtight tape.
