I have a new style house with lots of trusses in the roof can it be converted?

Yes, as we specialise in truss roof conversion we have a technical and innovative design package approved by the firms who provide the roof trusses so your NHBC guarantee is unaffected.

Is my loft tall enough for a conversion?

To comply to current building regulations you will need a minimum height from the top of the joist to the under -side of the ridge board of 2.1 metres - at this min height a dormer is advised

How long will it take to build?

Most of our loft conversions are ready to plaster within 4 weeks allowing 2-3 weeks for finishing such as carpentry, plumbing, tiling and electrics ready for you to decorate by week 8. Please allow an extra week or so for larger homes.

Is there much disruption during the works, do I have to move out?

The simple answer to this is no, as in most cases we use scaffolding with loading bays and cranes to lift all materials to roof level, this allows are construction crews to open a section of your roof to build your loft without coming through the inside of your property. It will only be necessary to enter your house at the beginning of week 4 to install your staircase, however at this time your roof will be weather tight and secure when we break through.

Do I have to get my architectural own drawings?

No, part of our service which is included in the price is to provide full architectural, design & structural calculations

Do I have to inform the council?

No, as part of our service we liaise with building control throughout the whole build and as part of the contract will make sure you obtain your approved final completion certificate.

How is the loft finished?

All our loft conversions are ready to decorate as we use a plaster finish, all the wood work is left natural ready for you to either a. fill prime and paint b. fill and varnish.

Is there much mess?

No, as the majority of the work is done outside the property, however once we break through for stair case (all done in one day) there will be disruption in this area for that day, however our crews use dust sheets and will tidy up afterwards.

Does a loft conversion add any value to my property?

Yes, provided it's done by a professional company with a creative design such as us and it adds the wow factor, as generally in England homes are valued by number of bedrooms and not square foot it is expected that you will get you money back and in most cases make a return.

Is there a guarantee?

Yes there is, we will offer a 5 year guarantee of which you can extend through the guild and master craftsman with insurance which will then become an insurance backed guarantee to give you piece of mind. However all of our loft conversions are approved and checked by your local authority showing that it is constructed in the proper manor.

How much is a loft conversion likely to cost on my property?

Usually most loft conversions start from £20.000 + VAT depending upon your requirements and the size of the property, for instance a mid-terraced house with a velux conversion giving one bedroom. If you require dormers add between £4,000 & £5,000 and if you are having a bathroom add approx. £2,500 with you supplying the suite but part of our service is to offer you a free feasibility survey and at this point we can be more specific on the price range.

Does a loft conversion require planning permission?

Generally unless you are in a conservation area, a listed building or a maisonette providing you're not projecting out of the roof space which faces the principle elevation i.e. usually your front door you will be exempt from planning permission and providing is does not exceed the required cubic capacity i.e. a. Terrace House 40 cubic metres, b. semi & detached 50 cubic metres. But please check our planning tab for more information.

Do I need to inform my insurance company?

It is advisable to let your insurance company know that you are having construction work done to the roof of your property and that you have scaffold erected for this. However we as a company have public liability which also covers for our workforce.
