Architectural Design and Planning

We take great passion in architectural design. Our experienced designers work closely on each project to meet the requirement and relevant approvals from planning. Our designers will listen carefully to your objectives, aims and dreams for the end result of your new space. For example finding out what your storage needs are so that these can be incorporated into the design. "Recognizing the need is the primary condition for design" - Charles Eames

Our design phase has a fixed fee solution so that you have clarity of the costs from the outset. Our architecture services online are nationwide in the United Kingdom.


During the design phase you will have a few stages and we will be there with you for all of them. We attend your property and survey with detail and accuracy for all the required measurements. This is called the site measured survey and ensures that your plans will be accurate. We believe that it is preferable for us to complete this for you so that you have the peace of mind that all the measurements and drawings are correct. 


The first step for all of our clients is a free consultation call, from this we will produce you a quote. If you are happy with this and ready to go ahead we will come to your property and do a full site survey. From this we will produce planning permission drawings, building regulation drawings, structural calculation drawings and party wall agreements.
