If you are building an extension within 3 metres of a neighbouring property you will most likley require a Party Wall Agreement with your neighbour.
Most extension projects require Party Wall Agreements. Depending on the layout you may need a PWA with more than one neighbour. You should also note that the neighbours are entitled to instruct their own surveyor and if they do, you would be expected to pay their costs also.

07: SAP Calculations
Sap Calculations may be required if your extension design includes excessive amount of glass. Under the building regs you are allowed up to 25% of the floor area to be used for glazing to the walls and ceiling.
If you exceed 25% you may have to have SAP Calculations carried out which will allow you to use more glass in return for upgrading existing elements within the original part of the house.
Draw Plans SAP Calc Costs From £ 350 Plus Vat
08: Specification & Schedule of Works / OPTIONAL
Having a costed Specification & Schedule of works done for your project is a great way of finding out at the early stages what the project is going to cost.
The schedule is also a big help when it comes to getting quotes as you can provide builders with an un-costed schedule and plans which means everyone is pricing the exact same job.
It is also a great negotiation tool because you will know if you are being overcharged on any of the works.

12: Cost v Value - Choosing a Designer
It all sounds easy enough, just place an enquiry online and wait for the quotes to come in and then pick the cheapest quote. You might save £100/£200 or even £300.
But before you do that you really should consider a few other factors and ask yourself:
Do you really want to choose the cheapest designer to work with on what is probably one of the biggest projects that most homeowners do in a lifetime?
Do you really want to choose a designer with little or no experience?
Do you really want to choose a starving designer that doesn't know how to submit a planning application or deal with the planners?
Do you really want to choose a designer that doesn't know how to create your building plans for building control?
What about adding value to your home? Do you really want to try and save £200/£300 on the cost of your plans and miss out on the potential to add the most value to your home? In effect save a few hundred on the design plans whilst possibly missing out on £50k in added value.
Extending your home is one of the biggest investments you are likely to make so don't make the crucial error of hiring the cheapest designer that won't have the knowledge and experience to ensure that your project is a complete success.
An experienced designer will know exactly how to add kerb appeal to your property and how to add the most value. They will also be able to guide and support you throughout the entire process.
An experienced designer will know exactly how to reduce your build costs, locate the various trades, source the best deals on double glazing, kitchens, flooring and save you several thousand during the process.
Experience is crucial to the success of the build as is a designer that can provide a full range of architectural services to support you throughout the project.
