Our prices
Our prices are detailed and transparent. We aim to save you money at every stage of a build.
For instance, we offer a design to planning consent service at £4800 flat fee, which is probably the best investment you could ever make, especially if you already own the land. We have a panel of architects nationwide and in France at varying prices who will work with you.
We also work with a number of regional partners such as project managers, structural engineers, renewable energy consultants and contractors who we can put you in touch with at good rates.
Our AvalonTM SIPS technology allows us to build the walls, floor and roof in the factory, complete with service conduits and electrical fittings, meaning that your home can be erected by 3 people in 2 weeks. The resulting structure is weather-proof, so it can be finished even in winter under rain.
This process, which we developed in Sweden, means that time to sale (if you are a developer), interest payments, site labour costs and management, can be far less than other construction techniques. As a rule of thumb, our price for a finished weather-proof structure with walls ready to plaster, triple glazed wood or composite windows and matching internal joinery (doors) is typically around £50 per square foot (£500 per square meter).
Be careful when comparing costs of 'timber frames' and check to see:
-
exactly what is included in the package - for instance, is it closed or open panel, or even just a pile of sticks? If you do buy a pile of sticks and build it entirely yourself, you might save some money, although the time, labour and mistakes onsite will usually mean the total cost of the finished build will be more than an advanced closed panel SIPS construction.
-
its quality and precise specification
-
exactly what is performed onsite and in the factory - most problems in construction are made by onsite, so the more done in the factory, the better.

TotalBuild
Our TotalBuild package is an all in price of £185 per square foot for a very high specification house - compare this with Huf - where we help you brief one of our architects of your choice and we give you the keys around 6 months after planning consent is granted. A stated amount is allowed for each item, for example, kitchens, bathrooms, floors, tiles, etc., and you can spend more or less than this on any item with the appropriate adjustments. TotalBuild puts the entire build responsibility on our shoulders.
ManagedBuild
Our ManagedBuild package puts you in charge of the cheque book, rather than us. It's a kind of halfway house between true self build and the traditional architect managed build. We will manage any and all parts of the build, depending on your wishes. If we manage everything, including project and site management, we charge flat fee of 15% of the build cost - which we would aim to more than save you in terms of time, hassle, and costs. Alternatively, an hourly rate can be arranged.
Stage Payments
We work to a general principle to break all payments into many smaller parts triggered against delivery and performance, so that your cash-flow is improved and your (and our) exposure is minimised.
Warranty
As we use rather clever technology in our Über SIPS, so we guarantee the frame for 50 years.
In general, Avalon™ SIPS packages will last as long as the best houses built in Elizabethan times that are still standing. The existence of thousands of timber buildings dating from the Middle Ages is testament to the durability of timber as a means of structural support.
Apparently, there’s still a bit of ‘Wood Henge’ in the ground today!
For Avalon™ Hempcrete and StrawBale SIPS packages, we guarantee these for 25 years, but once we get more familiar with the technology, we expect to provide the same 50 year warranty as for the Über SIPS.
