Planning an Extension

Planning an extension represents the single most important part of the process. Whatever your home extension plans, it pays to work with a trusted local contractor who understands the importance of comprehensive planning. With more than 22 years’ designing and installing home extensions across the region, Bluestone knows exactly what it means to provide outstanding extension planning services.

Planning an extension typically begins by working with an experienced architect to explore every available possibility. After which, planning permission may be required for the project to go ahead. Obtaining planning permission means providing the relevant council office with a detailed and complete copy of the extension plans, so as to illustrate its compliance with all relevant regulations.

After which, it is simply a case of agreeing on a final estimate or quote, before the installation process can begin.

Given the importance and complexities involved in planning an extension, it pays to have the professionals in your corner, every step of the way. As a customer committed contractor with unrivalled expertise, we insist on delivering the total service package from start to finish. Quite simply, you will not find a builder in the area with the same pride, passion and proven capabilities as Bluestone.

Cost of building an extension

Here at Bluestone, we understand that the cost of building an extension can be a point of concern. Particularly for those working with a limited budget, for whom price alone could determine whether or not the project goes ahead. By working with a dynamic price structure, we calculate each extension price in direct accordance with both the requirements and the available budgets of our customers. Which means that regardless of how much or how little you wish to spend, no builder in the area can deliver more for your money than Bluestone!

We firmly stand by every estimate we provide in terms of both fairness and value for money. In order to offer a final quote on any home extension service, we first need to complete a full evaluation and produce a detailed proposal. Nevertheless, as a customer-focused local contractor with a flawless reputation, we always do everything we can to keep every extension price as low as possible.

Our 100% bespoke services can be tailored to suit absolutely any budget whatsoever. Unlike others, we exclusively offer custom solutions that maximise value for money for every customer we work with.
