If you are calling a cell phone in a Mexican area code different from your own, you need to include the prefix 045. e.g. For a call from Guadalajara to a Mexico City mobile phone, dial 045-55-xxxx-xxxx.International calls to Mexican cell phones are dialed like regular international calls. e.g. To call a Mexico City mobile phone from the U.S., dial 011 + 52 + 1 + area code + number.TEP 2: Dial 52, Mexico's country calling code. STEP 3: Dial the 2-3-digit area code for the city you wish to call. STEP 4: Dial the 7-8-digit local subscriber number you wish to call. If you are having a hard time connecting, dial 00 for an international operator.
Rules of thumb to take into account when looking at the cost of building a house: 1  You should work towards a price of between $1200 and $1700 per m2. 2  The larger the home the cheaper the price per m2. 3  Its cheaper to build a single story home than it is to build a double story home.
As a rule of thumb you can add 50% extra to the build cost of a single storey extension. So, Â£24,000 +50% = Â£36,000. + Add on 10-15% for professional fees (architect, planning application, building regs, structural engineer).+ VAT.ou may have heard that the rule of thumb is Â£1,000 per m2. However, this figure has been bandied about for rather a long time now! From experience, Â£1,200 per m2 is a now a more realistic estimate for a house extension cost in 2015 and reflects price increases over the last few years.
