Our DIY build kits - What our customers say :

......I would just like to thank you for all your help and co-operation with the planning of our conservatory.....The whole project was a delight to build and we are totally thrilled with the end result.....

M Clark, Clacton.

Just a quick note to say the conservatory was of excellent quality and the installation went perfect with the help of the installation guide which was very easy to understand. Myself and the wife are very pleased with it, so would just like to thank you for your excellent service......

The Best Prefabricated Alternative to Conventional House Extensions

We are excited that there has been an increased demand for our building regs compliant prefabricated house extensions for diy builds, and for our supply and fitted option. Perfect for kitchen extensions , dining rooms , bedrooms or lounges . Our single storey extension kits are an excellent permanent alternative to conventional builds, with 20 year structural guarantees, and with various roof and footprint shapes. Much reduced build times (around 6-8 days) and considerably less ground works, are a huge benefit to busy households, removing weeks of mess and hassle. Garden access problems, drain bridging and sloping ground also make our kit a more viable and cost effective alternative to bricks and mortar home extensions requiring deep strip foundations and suspended block and lintel construction.

We would like to stress that our house extensions are a substantial alternative build comprising of : heavy gauge large box section coated steel for the base; galvanised heavy gauge formed steel box sections for the walls with real fired brick facings, in various colour options, or with a galvanised mesh for render coats; finally an aluminium eaves and deep rafters for the roof structure . We do not supply what we call timber 'sheds', with walls and roofs built out of lots of cheap, quick grown green timber with insulation sandwiched between exterior particle board sheets , which seems acceptable to joinery companies promoting timber frame extension systems

We offer real brick slip faced or stone faced walls in a large choice of colours and textures as well as a for render and timber cladding option . There is also a good range of roof tile and slate options and colours. Every extension is built to order, so there is a wide range of configurations available, with our extensive ranges of windows, doors and roofs either pitched or flat, combined with our Durabase Plus building regs compliant steel base and wall systems.Frankly you will be amazed at the number of house extension ideas we have.

Planning and building regulations - no problem

We are able to organise the building regulation application and inspections of our extension kit installations throughout the country with JHAI ( An independant building regs inspection company ) , for supply only projects or supply and build . We can also advise you on planning regulations requirements and refer you to our fixed price planning service we have organised with TCDS Plans - so give us a ring on 01452226290 if you are unsure what is required for your build and need good solid advise.

A more solid durable solution

Our prefabricated extensions, with their more solid build construction compared to conservatories and orangeries, provide a more private space for your living room, kitchen, bedroom , bathroom or home office. There are much higher levels of insulation, noise reduction and protection from the sun and elements, providing all year round comfort. Another very relevant point is there durability which outlasts conservatories, orangeries and timber only buildings by decades.

Durabase Plus steel bases with real brick faced or rendered walls

We use a Durabase Plus (regs approved) real brick faced modular base and wall system in our home extension kits to speed up your base and wall build - typically 2 days. These are multi-layered wall systems with galvanised heavy guage steel box formed construction - not cheap green timber, like many other external wall cladded SIP's systems. Durabases steel base and wall system has been established for over 20 years, so there is no better steel base and cladded wall system available. Please access our Durabase dedicated page above with installation video and extra information .

A typical build timescale is 5 - 7 days.
