How much will it cost?

Armstrong Architects can project manage your build from concept to completion or simply get your project through to the planning stage. We  undertake a wide range of projects from large new build developments to small kitchen extensions. We are a friendly practice who will complete your project with great professionalism and expertise. Please call to arrange for a free initial consultation at your property, which will be followed up with a fee quotation. In order to give you an example of our affordability, we provide some fees for straightforward projects below. Application fees, payable to your Local Authority and Fees for a Structural Engineer and/or other Consultants are not included in our prices.
If you simply wish to extend your home and have a clear idea of what you wish to achieve, then we can provide ‘as existing’ and ‘as proposed’ floor plans and elevations and make a planning application on your behalf. A simple single storey extension costs from £650, and a two storey extension costs from £750.



Alternatively, if you are unsure what you want and how to achieve the additional space you require then we offer a more detailed design service, with a sketch scheme stage including meeting(s) as necessary and a Budget Estimate. Typically a single storey extension costs from £800 for a detailed design service, and a two storey extension from £950 for a detailed design service, 

including making the Planning Application on your behalf.


The next stage is for more detailed drawings and specification. We would charge from £750 for a single storey extension and from £850 for a two storey extension.




New houses, barn conversions, large residential extensions and listed buildings are more complicated and we would quote following our initial consultation.




We would quote for Tender Packages, and Construction Packages following our initial consultation, as we would for Site Supervision, Project Management etc.
