Modern Extensions

The modern way to extend your home is with a flat roof (GRP Warm Roof) extension.

Couple this with bifold or sliding patio doors and you create a lovely bright living space.

Classic Style Extensions

Ultraroof is our favorite! It is the ultimate extension in Cornwall with the thermal properties of brick or super-insulated columns (depending on your choice) and the ultimate in lightweight tiled roof solutions.
Due to the strength of the Ultraroof beautiful vaulted ceilings can be created without the need for a tiebar.

Durabase Modern Builds

Building an Extension in Cornwall can be a messy experience, digging footings creating a mess in the garden, and on the drive. Older methods of base building are often messy and take a considerable amount of time. With Durabase there is very little mess, no waste to get rid of and the build is extremely quick. A complete base with walls and frames can be fitted in only two days.

Fast, Clean, Efficient

Older methods of extension building seem to be falling out of favor, largely due to the mess involved & the time that conventional builds take to erect. This is one of the reasons why we recommend a modular extension built using the Durabase and Ultraframe combination. Imagine a hassle-free option of building your dream living space! Everybody lives a busy lifestyle these days so any lengthy interruption to their daily life that a full construction project will inevitably bring is not good. With an Ultraframe and Durabase build, disruption is minimal, largely due to the ‘easy install’ nature of a modular build, therefore, time spent on site-building is much less.



Top Quality Products

The combination of the Ultraframe / Durabase product is easier to deliver and as an added bonus comes with many parts pre-installed which saves time cutting, measuring, and drilling on-site. The product is Pre-built in Ultraframes manufacturing facilities, the materials are all carefully chosen to suit your home. When designing a build they consider factors such as property types, property location, and snow load are all taken into consideration. The whole build is tailored to suit you and your home. Durabase and Ultraframe are the best products for any modular built extension and can be used for builds where access is a problem.

Will I need planning permission for a modular extension?

Can I customise my modular extension?

YES! The modular extensions can be customised in almost any way that you can think of. You can choose from a variety of materials such as uPVC or maybe you prefer the slimmer lines of the latest aluminium products. Colours and finishes are also largely customisable and allow you to design a modular extension into a bespoke build.

No servcies will need to be moved when installing one of our modular extensions.

Are Ultraframe products mass produced?

Ultraframe products are not mass-produced in the sense that the products are all the same. Modular extensions are of course far easier to create and set up thanks to their pre-fab design, however, every single design is a bespoke product that has been designed specifically for your property.
