New build in Bromley

Our client from Bromley wanted to build a new home. We designed a four-bedroom home with spacious interiors. On the ground floor we have designed a void which connects the kitchen to the basement space creating a connection between the main social areas of the house.

New Developments in North London

Our client was family property syndicate: Portman London Ltd. We have done many development proposals with them, and built a strong rapport based on trust and success. This project has probably been the largest one so far. This dynamic proposal is to add two storeys with eight luxury flats.

Planning Application Guidance

A new build home is a big deal for investors, not to mention owner-occupiers. It is very important to hire fully competent professionals to assist you throughout the process. Look for a new build architectural practice with experience of gaining planning approval for new developments across London from Haringey, to Hounslow and Muswell Hill to Mole Valley for your new build London proposal.


Find an architectural practice who can provide:

  • A full range of new build planning.
  • Pre-build and construction support services for Residential Planning Applications and Developments.
  • Can instruct technical services for you such as structural engineers.
  • You may need a Design and Access Statement (especially in Conservation Areas) or a Feasibility Report.
    • It will be more convenient for you if they have external report writers.

The Stages

It is good if they work in the 5 RIBA style stages to offer support all the way to construction. These follow the RIBA stage plan to simplify the process for you. If you book the complete route with us as far as project management and completion, they should offer generous block discounts when the stages are booked from the outset. That said, there should be an option to pick these up en route, so you can have relax and have the peace of mind to observe progress and enjoy the journey, leaving the details to a good architect.

The Benefits

One of the best things about planning new homes is to feel as if you have chosen and created all your ideas and finishes. You can design the room sizes as you wish, instead of reconfiguring the walls in houses for sale in London. If you are looking at plots with houses for sale in Central London, the changes and renovation can run to more expense than if you had levelled it and started over. If you need ideas and inspiration, your architects should have talented interior designers in-house.

Our Method for New Build Projects

There is a story behind each of the new builds we get asked about, yet new build architects: Extension Architecture can help with all of them. No project is too small or large. We organise technical services such as topographical surveys or structural calculations where needed. Our technicians can carry out detailed site surveys for planning and building regulations. Our team of architects and interior designers will come up with great scheme options for you, and our project managers will take over the construction phase.

New housing developments can tastefully change the face of London architecture – by contrasting a modern slant – in materials which are sympathetic to the surroundings. Good examples of this are two large London buildings which are true bastions of London Architecture, successfully mixing new and old within the same building. St Martins College of Art’s new home is a restored Granary building at Kings Cross. The architect for the original granary building – supplied bakers across London – had also designed Kings Cross Station. The other is the extension on the Natural History Museum on Exhibition Road, South Kensington.
