  The archetypal room over the garage side extension in Seaton Sluice

We offer a start-off consultation for home owners thinking of extending or altering their property.  For a set fee of only £90.00^* we will come and see you at your house, offer advice on what can and cannot be done, give you ideas of how to achieve what you want, and talk you through the entire process of having drawings prepared, obtaining Planning Permission and Building Regulations Approval, and finally selecting and appointing a contractor.

There is no time limit on these initial consultations, but most take between 45 and 90 minutes.  We can come out to see you after normal office hours so that you do not need to take time off work.

You are under no obligations to employ us further after this initial consultation but obviously we would like to think that our advice is such that you will.

*   Set fee of 90.00 applies to all locations within a 25 mile radius of our offices. Locations over this distance may have an additional mileage surcharge applied. Contact us for details.

Domestic Projects

Design Lines is one of only a handful of architects practices in the North East of England that are active in the domestic house alteration market.  We have done so many small alterations and additions to private houses that you could say that we specialise in it.

No job is too small for us ; we have undertaken domestic projects ranging from several extra room extensions right down to interior remodelling without needing to extend.  In fact we pride ourselves on being able to get the most out of the house you already have before or after extension.
