It's a wonderful scheme...IF you are already wealthy or already have a large pension pot. The rules are complicated and exhaustive. Basically you have to have a SIPP, self invested personal pension which is a personal pension plan that allows a lot of flexibility as to where the pension funds are invested. Most Sipps have a very high initial investment limit, 100K is not unusual. They are also subject to high management and annual charges.
The way it will work is this. From 6 April 2006, investors can buy a new property from existing funds in their Sipp or by using their annual contribution limit (set at the lower of £215,000 or their earnings for 2006/07). The property could be one they already own as a buy-to-let or holiday home, for instance - although there would be fees to pay such as stamp duty, land tax and conveyancing costs. The Sipp will be able to borrow up to 50 per cent of its assets, so if the Sipp has £200,000 in it, it could borrow another £100,000. This borrowing could be used to help buy the property, and the loan interest and repayments would be costs of the Sipp. Users of the property (whether buy-to-let tenants or the Sipp-plan holder living in his or her own home or visiting a holiday home) need to pay a commercial rent. The rental goes into the Sipp as non-taxable income.
If the Sipp holder uses their own property they will have to pay a commercial rent otherwise they forfeit their tax advantages.

In the short term I cannot see it having much effect on house prices in the UK or abroad. In the long term, I think if the government were seeing their scheme being taken advantage of and it having a negative effect on markets, then they would probably withdraw the scheme.
It really is for the rich at present but then they already get all the tax breaks so what is one more?
