An easy, quick self build extension kit

Perfect Solution

If you are looking to improve your home but have previously been put off due to high costs or legal restrictions, our timber frame extension kit is the perfect solution to add extra space and added value

Our single-story extension kit can be assembled in just one day. The structure comprises of a flat roof and two walls, as well as bi-fold doors from our external supplier – everything you need to create additional space which brings the outdoors in.

Our self build extension kit is manufactured from aesthetically pleasing and sustainable timber. The carbon footprint of the extension will be very small without compromising the structure’s performance or functionality.

Sustainable Construction

Once built, a timber extension can also offer a high level of insulation and airtightness, making it a great choice for a project with sustainability at its core.

Thanks to a one-load delivery and one-day construction time, disruption to the homeowner is minimal. Also, the extension does not require deep foundations, so less preparation time and work is required on-site. When constructing, the weather-tight stage can be met in hours rather than weeks, which also means your project can be less dependent on good weather conditions. Again, minimising the level of disruption.

When incorporating a timber frame extension into your self build project, consider what exterior finish you will need, whether you require planning permission and what is achievable within your budget.

Advantages of Timber Frame Construction. Low embodied energy if constructed in local timber. Reduced construction waste through efficient controlled manufacturing. Low volume of waste on site requiring removal. Quick build time.Read our ‘How Much Do Different Types of Roof Trusses Cost?’ article for more information.

A timber frame weighs much less than bricks and blocks, so less of a foundation is required and, therefore, making it less expensive to begin with.

As the timber extension kits only require a one-day build time, there are less/almost no on-site costs such as project management, rent of equipment or multiple builders to pay for construction.

Work inside your timber extension can be started as soon as the frame is up and the outside walls are complete. As it is mainly a ‘dry’ process and can be watertight pretty much straight away, you avoid waiting for the drying out of the ‘wet’ structure of bricks and mortar.

Yes, all of our designs are bespoke to each individual client’s requirements.

At the time of your enquiry we will discuss with you the extent of the package you want from us. This can be just the structural wall panels, floor joists and roof timbers or we can add in insulation, vapour control layer (VCL), battens, brick ties and more, we will tailor the package to suit you.

The permitted development rules have recently been relaxed, allowing you to build an extension without planning permission of up to six metres (or eight metres if your house is detached) in England.

No – you will need to employ a local architect to prepare your drawings and carry out your submission.

Yes, Pasquill are nationwide, covering the whole of the United Kingdom.

Yes, once an order is placed we will send you fully detailed and dimensioned drawings that show the overall wall lengths and heights so that both your builder and architect can view, check and confirm to us that these are correct before we start manufacture.

The foundation specification will be site dependent and will be designed and inspected as part of the Building Control/Regulation process.

Yes, the external finish is decorative and can be either timber or masonry.

Yes, it is likely that timber frame will be significantly faster than traditional method. All walls are built and partially assembled in our factory, they are then joined together when they arrive at your site. In some cases this can take a matter of hours.

As long as the construction is being carried out safely, timber frame can be installed in the rain. With the off-site manufacturing of our kits and the installation time of just one day, this means  less worrying about weather conditions delaying the job.
