In-house Expertise

In-House Expertise

With unrivalled experience in both the design and construction of residential projects, including self-build houses, home extensions, and loft conversions, we have been providing a first-class service for the past five years to clients across the UK. Our team of experts delivers bespoke solutions tailored to your needs, ensuring quality and precision at every stage.

Why Get A New Build?

Building a new home offers a unique opportunity to design a space that perfectly fits your lifestyle from the ground up. With a custom build, you can choose every detail, from the layout to the finishes, ensuring the home is tailored to your needs and preferences.

A new-build also provides the benefit of modern construction standards, offering better energy efficiency, lower maintenance costs, and compliance with the latest building regulations.

In the UK, opting for a self-build can save you significantly compared to purchasing a developer-built home. Research shows that building your own home can cost 25–30% less than buying a comparable new property from a developer, thanks to savings on construction costs and the exclusion of developer profits. For example, the average cost of constructing a self-build home is around £2,200 per square metre, often yielding a higher-quality result for the same or lower price.

Our new-build service guides you through the entire process, delivering expertly crafted architectural designs and building regulation drawings to bring your dream home to life.

Types of Plots

Backland-plot

Backland Plot

Backland plots--often former gardens behind existing homes--offer great new build potential but require careful planning. We specialise in unlocking these hidden sites, managing the full process from feasibility and design to planning applications and structural engineering calculations. Whether you're considering a self-build or multiple units to sell, we maximise land value through tailored architectural solutions that meet local policy. Our team ensures every backland site is used efficiently, without compromising privacy or access.

Side-plot

Side Plot

Side plots--such as wide driveways, side gardens, or land next to existing homes--are ideal for compact new build projects. These often include space currently occupied by sheds or unused garages. We provide end-to-end services including feasibilty, design, planning, and structural engineering calculations. Whether it's a self-build home or a development to sell, we design smart, space-efficient solutions that meet planning requirements and optimise every square metre of your land.

Infill-plot

Infill Plot

Infill plots—gaps between properties often created by wide gardens or removed garages—offer excellent new build opportunities. These sites demand designs that respond well to their surroundings. We manage the full development process, including site assessments, design, planning submissions, and structural engineering calculations. Whether for a self build home or a multi-unit scheme, our solutions maximise space and align with local planning policy, helping you turn underused land into valuable property.

Frequently Asked Questions

Q. Can I build another house in my garden in the UK?

Yes, you can build another house in your garden in the UK, provided you secure planning permission from your local authority. This type of development, known as backland, side plot or infill development, is common. To move forward, it's essential to submit well-prepared plans that align with local policy.

Q. Can I build a house on my land in the UK?

Yes, you can build a house on your land, but you must obtain planning permission from your local council. The process will depend on the catergorisation of the land, especially if it's in a protected area like the Green Belt. However, with proper planning and design, building on your land is achievable.

Q. How much does it cost to build a new house in the UK?

The average cost of building a new house in the UK is between £1,750 and £3,000 per square metre. For a standard three-bedroom house, this typically amounts to £270,000 to £360,000, depending on location, materials, and finishes.

Q. How much does a traditional architect cost to design a house in the UK?

Traditional architect fees usually range between 5% to 15% of the total construction cost. For a typical house build, this means you can expect to pay between £5,000 and £30,000, depending on the project's complexity.

Q. Can you design your own house in the UK?

Yes, you can design your own house in the UK. While you can create the initial design yourself, you'll need the help of a qualified architectural designer or structural engineer to ensure that your plans comply with building regulations and are approved for construction.
