We offer an obligation and cost-free evaluation and consultation. This involves a site visit so we can understand your vision for your house extension project. You can let us know exactly what you want in terms of function, layout, features and finishes. You will be invited to browse our portfolio of completed house extensions and house remodelling projects in London to help your ideas take shape. We’ll go over any relevant planning laws, discuss your budget and talk you through what’s involved so you can make an informed decision on whether to go ahead with the project.
If you don’t have a concrete idea of exactly what you want or you simply want to assess your options, our comprehensive feasibility analysis is here to help. It will outline which of the many house extension options are open to you for your particular property. This allows you to see exactly how much additional space you can create, and how you can optimise the use of space you already have. You can compare benefits and costs of the different house extension options and make the right choice for what will work best for you.
Certain information will be needed to inform the technical and practical aspects of your planned house extension design and construction. Usually, this will be collected through surveys to establish things like: precise dimensions of the site; ease of access for equipment and tools; soil structure; location of load-bearing walls if these are to be remodelled, and the position of any trees and drains which might influence or affect the design. These surveys may need to be included with any planning application.
Our architect will begin creating sketches and concept designs to bring your ideas alive. You can decide on fixtures, fittings materials and finishes. You can experience what your house extension design will look like in 3D and what the space will feel like in a virtual 3D walkthrough. If you see something you would like to change – no problem! We’ll work on the designs with you until you’re 100% delighted.
We understand the planning process in London and the Greater London area inside-out. We can advise you of any restrictions relating to your house or area at the initial stages so that they can inform the design of your house extension. We’ll draw up and submit all necessary drawings and documents to the relevant authorities on your behalf.
Estimation and Budgeting
With design and finishes agreed, our architect can now produce the technical drawings for your house extension for our quantity surveyor to cost up for you. You’ll receive a fully itemised, guaranteed, fixed-price quote.

- any structural changes to existing walls may involve additional costs
- if gas meters, pipework, drains, etc have to be moved
CASE STUDY – SHOREDITCH
The client was keen for this apartment within an industrial building once used as a furniture factory to reflect the industrial character and scale of the space. The project saw removal of earlier divisions to allow shafts of sunlight from the large, light-feeding windows in the South and West walls to flood the area which faces the courtyard of the building. The large amount of lateral space supplies zones for relaxing, dining, exercise, and utility. The period charm of the former furniture factory has been retained and the rare character of the building survives in beautiful areas of exposed brickwork, salvaged oak floors and an expansive open-plan layout.
